-# Theodosius - Jit linker, Mapper, Mutator, and Obfuscator
-
-Theodosius (Theo for short) is a jit linker created entirely for obfuscation and mutation of both code, and code flow. The project is extremely modular in design and supports
-both kernel and usermode projects. Since Theo inherits HMDM (highly modular driver mapper), any vulnerable driver that exposes arbitrary MSR writes, or physical memory read/write can be used with this framework to map unsigned code into the kernel. This is possible since HMDM inherits VDM (vulnerable driver manipulation), and MSREXEC (elevation of arbitrary MSR writes to kernel execution).
-
-Theo can be used for many projects. The modularity of the code allows for a programmer to use this framework however they please. A few example usages of Theo would be, streaming code and data from a .lib over a network directly into memory, resolving unexported symbols via PDB, allocating each instruction of a function inside of code caves, and much more.

-## Linking - Dynamic And Static
-
-#### What Is A Linker
-
-A linker is a program which takes object files produces by a compiler and generates a final executable native to the operating system. A linker interfaces with not only object files but also static libraries, "lib" files. What is a "lib" file? Well a lib file is just an archive of obj's. You can invision it as a zip/rar without any compression, just concatination of said object files.
-
-Theo is a jit linker, which means it will link objs together and map them into memory all at once. For usability however, instead of handling object files, Theo can parse entire lib files and extract the objects out of the lib.
-
-#### Object Files
-
-If you define a c++ file called "main.cpp" the compiler will generate an object file by the name of "main.obj". When you refer to data or code defined in another c/c++ file, the linker uses a symbol table to resolve the address of said code/data. In this situation I am the linker and I resolve all of your symbols :).
-
-#### Static Linking
-
-Static linking is when the linker links entire routines not created by you, into your code. Say `memcpy` (if its not inlined), will be staticlly linked with the CRT. Static linking also allows for your code to be more independant as all the code you need you bring with you. However, with Theo, you cannot link static libraries which are not compiled with `mcmodel=large`. Theo supports actual static linking, in other words, using multiple static libraries at the same time.
-
-#### Dynamic Linking
-
-Dynamic linking is when external symbols are resolved at runtime. This is done by imports and exports in DLL's (dynamiclly linked libraries). Theo supports "dynamic linking", or in better terms, linking against exported routines. You can see examples of this inside of both usermode and kernelmode examples.
-
-# Usage - Using Theodosius
-
-## Integrating Clang
-
-For integration with visual studios please open install [llvm2019](https://marketplace.visualstudio.com/items?itemName=MarekAniola.mangh-llvm2019) extension, or [llvm2017](https://marketplace.visualstudio.com/items?itemName=LLVMExtensions.llvm-toolchain) extension. Once installed, create or open a visual studio project which you want to use with LLVM-Obfuscator and Theo. Open ***Properties*** --> ***Configuration Properties*** ---> ***General***, then set ***Platform Toolset*** to ***LLVM***.
-
-Once LLVM is selected, under the ***LLVM*** tab change the clang-cl location to the place where you extracted [clang-cl.rar](https://githacks.org/_xeroxz/theodosius/-/blob/cc9496ccceba3d1f0916859ddb2583be9362c908/resources/clang-cl.rar). Finally under ***Additional Compiler Options*** (same LLVM tab), set the following: `-Xclang -std=c++1z -Xclang -mcode-model -Xclang large -Xclang -fno-jump-tables -mllvm -split -mllvm -split_num=4 -mllvm -sub_loop=4`.
-
-Please refer to the [LLVM-Obfuscator Wiki](https://github.com/obfuscator-llvm/obfuscator/wiki) for more information on commandline arguments.
-
-#### Requirements
-
-* No SEH support, do not add `__try/__except` in your code.
-* No CFG (control flow guard) support. Please disable this in C/C++ ---> Code Generation ---> Control Flow Guard
-* No Stack Security Check Support. Please disablel this in C/C++ ---> Code Generation ---> Security Check (/GS-)
-* Your project must be set to produce a .lib file.
-* Your project must not link with other static libraries which are not compiled with `-Xclang -mcmodel-large`.
-* Project must be compiled with the following flags
- * `-Xclang -mcmodel=large`, removes RIP relative addressing besides JCC's.
- * `-Xclang -fno-jump-tables`, removes jump tables created by switch cases.
- * `/Zc:threadSafeInit-`, static will not use TLS (thread local storage).
-
-## Lambdas For Explicit Constructor
-
-Theodosius uses the same class structure as HMDM does. Its a highly modular format which allows for extreme usage, supporting almost every idea one might have. In order to use Theo, you must first define three lambdas, `theo::memcpy_t` a method of copying memory, `theo::malloc_t` a method to allocate executable memory, and lastely `theo::resolve_symbol_t` a lamdba to resolve external symbols.
-
-### `theo::memcpy_t` - copy memory lambda
-
-This is used to write memory, it is never used to read memory. An example of this lambda using VDM could be:
-
-```cpp
-theo::memcpy_t _kmemcpy =
-[&](void* dest, const void* src, std::size_t size) -> void*
-{
- static const auto kmemcpy =
- reinterpret_cast(
- utils::kmodule::get_export(
- "ntoskrnl.exe", "memcpy"));
-
- return vdm.syscall(kmemcpy, dest, src, size);
-};
-```
-
-This uses VDM to syscall into memcpy exported by ntoskrnl... If you want to do something in usermode you can proxy memcpy to `WriteProcessMemory` or any other method of writing memory.
-
-```cpp
-theo::memcpy_t _memcpy =
-[&](void* dest, const void* src, std::size_t size) -> void*
-{
- SIZE_T bytes_handled;
- if (!WriteProcessMemory(phandle, dest, src, size, &bytes_handled))
- {
- std::printf("[!] failed to write process memory...\n");
- exit(-1);
- }
- return dest;
-};
-```
-
-### `theo::malloc_t` - allocate executable memory
-
-This lambda is used to allocate executable memory. Any method will do as long as the memcpy lambda can write to the allocated memory. An MSREXEC example for this lambda is defined below.
-
-```cpp
-theo::malloc_t _kalloc = [&](std::size_t size) -> void*
-{
- void* alloc_base;
- msrexec.exec
- (
- [&](void* krnl_base, get_system_routine_t get_kroutine) -> void
- {
- using ex_alloc_pool_t =
- void* (*)(std::uint32_t, std::size_t);
-
- const auto ex_alloc_pool =
- reinterpret_cast(
- get_kroutine(krnl_base, "ExAllocatePool"));
-
- alloc_base = ex_alloc_pool(NULL, size);
- }
- );
- return alloc_base;
-};
-```
-
-This lambda uses MSREXEC to allocate kernel memory via ExAllocatePool. However this is completely open ended on how you want to do it, you can allocate your memory into discarded
-sections, you can allocate your memory in another address space, etc... Its extremely modular.
-
-
-Another, yet simple, usermode example for this lambda is defined below.
-
-```cpp
-theo::malloc_t _alloc = [&](std::size_t size) -> void*
-{
- return VirtualAllocEx
- (
- phandle,
- nullptr,
- size,
- MEM_COMMIT | MEM_RESERVE,
- PAGE_EXECUTE_READWRITE
- );
-};
-```
-
-### `theo::resolve_symbol_t` - resolve external symbol
-
-This lambda will try and resolve external symbols. Symbols which are not defined inside of any object files. For example `PiddbCacheTable`, an unexported ntoskrnl symbol, which normally people sig scan for, can now be jit linked. This is possible by parsing a MAP file, however you can recode this to support PDB's, etc. Again its completely opened ended on how you want to resolve symbols.
-
-```cpp
-theo::resolve_symbol_t resolve_symbol =
-[&, &extern_symbols = extern_symbols](const char* symbol_name) -> std::uintptr_t
-{
- std::uintptr_t result = 0u;
- for (auto& [drv_name, drv_symbols] : extern_symbols)
- {
- // each kernel module... find a driver with a matching map file name...
- // I.E ntoskrnl.exe.map == ntoskrnl.exe...
- utils::kmodule::each_module
- (
- [&, &drv_name = drv_name, &drv_symbols = drv_symbols]
- (PRTL_PROCESS_MODULE_INFORMATION drv_info, const char* drv_path) -> bool
- {
- const auto _drv_name =
- reinterpret_cast(
- drv_info->OffsetToFileName + drv_info->FullPathName);
-
- // if this is the driver, load it, loop over its sections
- // calc the absolute virtual address of the symbol...
- if (!strcmp(_drv_name, drv_name.c_str()))
- {
- const auto drv_load_addr =
- reinterpret_cast(
- LoadLibraryExA(drv_path, NULL, DONT_RESOLVE_DLL_REFERENCES));
-
- std::uint32_t section_count = 1u;
- utils::pe::each_section
- (
- [&, &drv_symbols = drv_symbols]
- (PIMAGE_SECTION_HEADER section_header, std::uintptr_t img_base) -> bool
- {
- if (section_count == drv_symbols[symbol_name].first)
- {
- result = reinterpret_cast(drv_info->ImageBase) +
- section_header->VirtualAddress + drv_symbols[symbol_name].second;
-
- // we found the symbol...
- return false;
- }
-
- ++section_count;
- // keep going over sections...
- return true;
- }, drv_load_addr
- );
- }
-
- // keep looping over modules until we resolve the symbol...
- return !result;
- }
- );
- }
-
- // if the symbol was not resolved in any of the map files then try
- // to see if its an export from any other drivers...
- if (!result)
- {
- utils::kmodule::each_module
- (
- [&](PRTL_PROCESS_MODULE_INFORMATION drv_info, const char* drv_path) -> bool
- {
- const auto drv_name =
- reinterpret_cast(
- drv_info->OffsetToFileName + drv_info->FullPathName);
-
- // false if we found the symbol...
- return (!(result = utils::kmodule::get_export(drv_name, symbol_name)));
- }
- );
- }
-
- return result;
-};
-```
-
-Another example of this lambda can be viewed in the usermode examples. This routine simply loops over every single module mapped into the specific process you want to map/link with.
-
-```cpp
-theo::resolve_symbol_t _resolver =
- [&, &extern_symbols = extern_symbols](const char* symbol_name) -> std::uintptr_t
-{
- auto loaded_modules = std::make_unique(64);
- std::uintptr_t result = 0u, loaded_module_sz = 0u;
-
- if (!EnumProcessModules(phandle,
- loaded_modules.get(), 512, (PDWORD)&loaded_module_sz))
- return {};
-
- for (auto i = 0u; i < loaded_module_sz / 8u; i++)
- {
- wchar_t file_name[MAX_PATH] = L"";
- if (!GetModuleFileNameExW(phandle,
- loaded_modules.get()[i], file_name, _countof(file_name)))
- continue;
-
- if ((result = reinterpret_cast(
- GetProcAddress(LoadLibrary(file_name), symbol_name))))
- break;
- }
-
- return result;
-};
-```
-
-### Creating Instance
-
-Once all three lambdas are defined, you can then create a `theo::hmm_ctx` (highly modular mapper context). This class is like the one from HMDM however it requires an extra lambda to resolve external symbols.
-
-```cpp
-theo::hmm_ctx drv_mapper({ _alloc, _memcpy, _resolver });
-
-const auto drv_entry =
- reinterpret_cast(
- drv_mapper.map_objs(image_objs));
-```
-
-### Calling Entry
-
-#### MSREXEC - Call Entry Example
-
-The entry point of the mapped code is not invoked by `hmm_ctx`, but rather its left up to you to call. An example of calling the entry point can be seen below.
-
-```cpp
-int result;
-msrexec.exec([&result, drv_entry = drv_entry]
- (void* krnl_base, get_system_routine_t get_kroutine) -> void
-{
- using drv_entry_t = int(*)();
- result = reinterpret_cast(drv_entry)();
-});
-```
-
-#### VDM - Call Entry Example
-
-Another example, this one using VDM, can be seen below.
-
-```cpp
-const auto entry_result =
- vdm.syscall(
- reinterpret_cast(drv_entry));
-```
-
-#### WinAPI - Call Entry Example
-
-Another example, this one using WinAPI's, can be seen below.
-
-```cpp
-std::uint32_t tid = 0u;
-CreateRemoteThread
-(
- phandle, NULL,
- NULL, drv_entry,
- NULL, NULL,
- (LPDWORD)&tid
-);
-```
-
-## RIP Relative Addressing
-
-In order to allow for a routine to be scattered throughout a 64bit address space, RIP relative addressing must not be used. In order to facilitate this, a very special version
-of clang-cl is used which can use `mcmodel=large`. This will generate instructions which do not use RIP relative addressing when referencing symbols outside of the routine in which the
-instruction itself resides. The only exception to this is JCC instructions, (besides call) also known as branching instructions. Take this c++ code for an example:
-
-```cpp
-ObfuscateRoutine
-extern "C" int ModuleEntry()
-{
- MessageBoxA(0, "Demo", "Hello From Obfuscated Routine!", 0);
- UsermodeMutateDemo();
- UsermodeNoObfuscation();
-}
-```
-
-This c++ function, compiled by clang-cl with `mcmodel=large`, will generate a routine with the following instructions:
-
-```
-0x00: ; void UsermodeNoObfuscation(void)
-0x00: public ?UsermodeNoObfuscation@@YAXXZ
-0x00: ?UsermodeNoObfuscation@@YAXXZ proc near ; CODE XREF: ModuleEntry+42↓p
-0x00: var_4 = dword ptr -4
-0x00: 48 83 EC 28 sub rsp, 28h
-0x04: C7 44 24 24 00 00 00 00 mov [rsp+28h+var_4], 0
-0x0C: loc_C:
-0x0C: 83 7C 24 24 05 cmp [rsp+28h+var_4], 5
-0x11: 0F 83 38 00 00 00 jnb loc_4F
-0x17: 31 C0 xor eax, eax
-0x19: 48 BA 28 01 00 00 00 00 00 00 mov rdx, offset ??_C@_04DKDMNOEB@Demo?$AA@ ; "Demo"
-0x23: 49 B8 00 01 00 00 00 00 00 00 mov r8, offset ??_C@_0CD@JEJKPGNA@Hello?5... ; "Hello From Non-Obfuscated Routine!"
-0x2D: 48 B8 A0 01 00 00 00 00 00 00 mov rax, offset MessageBoxA
-0x37: 45 31 C9 xor r9d, r9d ; uType
-0x3A: 44 89 C9 mov ecx, r9d ; hWnd
-0x3D: FF D0 call rax ; MessageBoxA
-0x3F: 8B 44 24 24 mov eax, [rsp+28h+var_4]
-0x43: 83 C0 01 add eax, 1
-0x46: 89 44 24 24 mov [rsp+28h+var_4], eax
-0x4A: E9 BD FF FF FF jmp loc_C
-0x4F: loc_4F:
-0x4F: 48 83 C4 28 add rsp, 28h
-0x53: C3 retn
-0x53: ?UsermodeNoObfuscation@@YAXXZ endp
-```
-
-As you can see from the code above, (sorry for the terrible syntax highlighting), references to strings and calls to functions are done by first loading the address of the symbol into a register and then interfacing with the symbol.
-
-```
-0x2D: 48 B8 A0 01 00 00 00 00 00 00 mov rax, offset MessageBoxA
-; ...
-0x3D: FF D0 call rax ; MessageBoxA
-```
-
-Each of these instructions can be anywhere in virtual memory and it would not effect code execution one bit. However this is not the case with routines which have conditional branches. Take the following c++ code for example.
-
-## JCC - RIP Relative
-
-```cpp
-ObfuscateRoutine
-void LoopDemo()
-{
- for (auto idx = 0u; idx < 10; ++idx)
- DbgPrint("> Loop Demo: %d\n", idx);
-}
-```
-
-This c++ function, compiled by clang-cl with `mcmodel=large`, will generate a routine with the following instructions:
-
-```
-0x58 ; void LoopDemo(void)
-0x58 public ?LoopDemo@@YAXXZ
-0x58 ?LoopDemo@@YAXXZ proc near
-0x58 var_4 = dword ptr -4
-0x58
-0x58 48 83 EC 28 sub rsp, 28h
-0x5C C7 44 24 24 00 00 00 00 mov [rsp+28h+var_4], 0
-0x64 loc_64:
-0x64 83 7C 24 24 0A cmp [rsp+28h+var_4], 0Ah
-0x69 0F 83 2A 00 00 00 jnb loc_99
-0x6F 8B 54 24 24 mov edx, [rsp+28h+var_4]
-0x73 48 B9 60 01 00 00 00 00 00 00 mov rcx, offset ??_C@_0BB@HGKDPLMC@?$.... ; "> Loop Demo: %d\n"
-0x7D 48 B8 38 02 00 00 00 00 00 00 mov rax, offset DbgPrint
-0x87 FF D0 call rax ; DbgPrint
-0x89 8B 44 24 24 mov eax, [rsp+28h+var_4]
-0x8D 83 C0 01 add eax, 1

-0x9D ?LoopDemo@@YAXXZ endp
-```
-
-Uh oh, `jnb loc_99`?, thats RIP relative! In order to handle branching operations, a "jump table" is generated by `obfuscation::obfuscate` explicit default constructor. Instead of branching to the RIP relative code, it will instead branch to an inline jump (`JMP [RIP+0x0]`). As demonstrated below, the branching operation is altered to branch to an asbolute jump.
-
-```
-ffff998b`c5369e60 0f830e000000 jnb ffff998b`c5369e74
-ffff998b`c5369e66 ff2500000000 jmp qword ptr [ffff998b`c5369e6c]
-...
-ffff998b`c5369e74 ff2500000000 jmp qword ptr [ffff998b`c5369e7a]
-```
-
-The linker is able to get the address of the branching code by taking the rip relative virtual address of the branching operation, which is a signed number, and adding it to the current byte offset into the current routine, plus the size of the branching instruction. For example `LoopDemo@17` + size of the branching instruction, which is six bytes, then adding the signed relative virtual address (0x2A). The result of this simple calculation gives us `LoopDemo@65`, which is correct, the branch goes to `add rsp, 28h` in the above example.
-
-## Obfuscation
-
-The usage of the word obfuscation in this project is use to define any changes made to code, this includes code flow. `obfuscation::obfuscate`, a base class, which is inherited and expanded upon by `obfuscation::mutation`, obfuscates code flow by inserting `JMP [RIP+0x0]` instructions after every single instruction. This allows for a routine to be broken up into unique allocations of memory and thus provides more canvas room for creative ideas.
-
-### Obfuscate - Base Class
-
-The base class, as described in the above section, contains a handful of util routines and a single explicit constructor which is the corner stone of the class. The constructor fixes JCC relative virtual addresses so that if the condition is met, instead of jumping instruction pointer relativitly, it will jump to an addition jmp (`JMP [RIP+0x0]`).
-
-
-LEA's, nor CALL's are rip relative, even for symbols defined inside of the routine in which the instruction is compiled into. In other words JCC instructions are the only instruction pointer relative instructions that are generated.
-
-
-```
-instruction
-jmp next instruction
-
-
-instruction
-jmp next instruction
-
-
-instruction
-jmp next instruction
-```
-
-### Mutation - Inherts Obfuscation
-
-This class inherits from `obfuscate` and adds additional code, or "mutation". This class is a small example of how to use inheritance with `obfuscate` base class. It generates a stack push/pop palindrome. The state of the stack is restored before the routines actual instruction is executed. The assembly will now look like this in memory:
-
-```
-push gp
-push gp
-push gp
-...
-pop gp
-pop gp
-pop gp
-exec routine instruction
-jmp next instruction
-
-push gp
-push gp
-push gp
-push gp
-push gp
-...
-pop gp
-pop gp
-pop gp
-pop gp
-pop gp
-exec routine instruction
-jmp next instruction
-
-push gp
-push gp
-push gp
-...
-pop gp
-pop gp
-pop gp
-exec routine instruction
-jmp next instruction
-```
-
-Again this is just a demo/POC on how you can inherit `obfuscate`. This also shows an example of how to use `asmjit`.
-
-# Examples
-
-### Kernel Example
-
-
-
-This example uses MSREXEC and Theodosius to map unsigned code into the kernel. This example is inside of the "Examples" folder. I would also like to note that in this demo external unexported ntoskrnl symbols are resolved by using a MAP file. This map file looks like this:
-
-```
- 00000001:0000000000000F10 KiOpTwoByteTable
- 00000001:0000000000001168 SeSubsystemName
- 00000001:0000000000001180 PlugPlayHandlerTable
- 00000001:00000000000013E0 PiDmAggregatedBooleanDefs
- 00000001:0000000000001490 PiDmCachedDeviceKeys
- 00000001:0000000000001580 PiDmCachedDeviceInterfaceKeys
- 00000001:00000000000015F0 AllowedCachedObjectNames
- 00000001:0000000000001640 EmptyUnicodeString
-```
-
-Mind the space at the beginning of each line. If you want to generate a file like this, put ntoskrnl.exe into IDA Pro and then click File ---> Produce File ---> Create MAP File, dont select "Segment Information", but do select "Demangled Names". After the MAP file is generate, please delete all of the garbage at the beginning of the file. I.E delete all spaces and "Address, Public By Value" stuff.
-
-```
-
-
- Address Publics by Value
-
- 00000001:0000000000000000 VrpRegistryString
- ....
-```
-
-Once you have generated a map file for ntoskrnl.exe, or any other binary you want to link with, you can then use it to resolve external symbols. In the `DemoDrv` project, I reference two external symbols. One being `PiddbCacheTable`, and the other being a win32kfull.sys export.
-
-```cpp
-// this is a demo of resolving non-exported symbols...
-// win32kfull.sys export example...
-extern "C" void NtUserRegisterShellPTPListener();
-extern "C" void* PiDDBCacheTable;
-
-```
-
-These two symbols are simply printed out via DbgPrint.
-
-```cpp
-MutateRoutine extern "C" void DrvEntry()
-{
- DbgPrint("> Hello World!\n");
-
- // non-exported symbols being resolved by jit linker...
- DbgPrint("> PiDDBCacheTable = 0x%p\n", &PiDDBCacheTable);
- DbgPrint("> win32kfull!NtUserRegisterShellPTPListener = 0x%p\n", &NtUserRegisterShellPTPListener);
-
- // example of referencing itself...
- DbgPrint("> DrvEntry = 0x%p\n", &DrvEntry);
-
- // example of calling other obfuscated/non obfuscated routines...
- PrintCR3();
- LoopDemo();
-}
-```
-
-Once compiled the assembly will look like this. Note that each reference to symbols is done via a relocation to an absolute address. This means strings can (and will) be mapped into their own allocation of memory.
-
-```

-
-Theo calculates the size of each symbol by subtracting the address of the next symbol (in the same section), from the address of the symbol itself. If the symbol is the last one in a section, the distance between the start of the symbol and the end of the section is used. Now lets take a look at what happens when we link/map this routine. Theo starts by allocating space for all non-obfuscated symbols.
-
-```
-[+] allocating space for symbols...
- > ??_C@_0BG@GFEIGDHO@?$DO?5Current?5CR3?5?$DN?50x?$CFp?6?$AA@ allocated at = 0xFFFF998BC5361FB0, size = 22
- > ??_C@_0BB@HGKDPLMC@?$DO?5Loop?5Demo?3?5?$CFd?6?$AA@ allocated at = 0xFFFF998BC5364FA0, size = 17

- > ?PrintCR3@@YAXXZ allocated at = 0xFFFF998BC5366F80, size = 58
-```
-
-As you can see, each string gets its own pool, each global variable does too, and every non-obfuscated routine is mapped into its own pool. The memory however, has not been copied yet since there are relocations that need to happen before they are copied into memory (in PrintCr3).
-
-The next thing Theo does is allocate space for obfuscated routines. In the `DemoDrv`, there is a demo for each type of obfuscation (just mutation and control flow obfuscation for now).
-
-```
-[+] allocating space for obfuscated symbols...
- > ?LoopDemo@@YAXXZ allocated = 0xFFFF998BC5369DA0, size = 18
- > ?LoopDemo@@YAXXZ@4 allocated = 0xFFFF998BC5369DE0, size = 22
- > ?LoopDemo@@YAXXZ@12 allocated = 0xFFFF998BC5369E20, size = 19

- > ?LoopDemo@@YAXXZ@69 allocated = 0xFFFF998BC5368C90, size = 15
-```
-
-As you can see, Theo uses Zydis to go over all routines marked for obfuscation and generates new symbols for each instruction inside of the routine. The symbol goes by `[RoutineName]@[Instruction Offset]`. Note that JCC's are indeed rip relative, these need to be fixed.
-
-```
-> fixing JCC rva...
- > new rva = 0xe
- > old rva = 0x2a
-> ?LoopDemo@@YAXXZ@17 allocated = 0xFFFF998BC5369E60, size = 34
-```
-
-Note that in DemoDrv there is a function called "LoopDemo" which is obfuscated. Instead of the JCC instruction branching to the conditional code, it instead branches to an inline jmp. If it doesnt branch, then it simply jumps to the next instruction like normal.
-
-```
-ffff998b`c5369e60 0f830e000000 jae ffff998b`c5369e74
-ffff998b`c5369e66 ff2500000000 jmp qword ptr [ffff998b`c5369e6c]
-ffff998b`c5369e74 ff2500000000 jmp qword ptr [ffff998b`c5369e7a]
-```
-
-As you can see above, this is what Theo generates for JCC's. Also note that this clang compiler does not generate RIP relative LEA's or CALL's. The only RIP relative stuff Theo deals with are JCC's.
-
-#### Memory View Of Obfuscation

-// dear imgui: Renderer Backend for DirectX11
-// This needs to be used along with a Platform Backend (e.g. Win32)
-
-// Implemented features:
-// [X] Renderer: User texture binding. Use 'ID3D11ShaderResourceView*' as ImTextureID. Read the FAQ about ImTextureID!
-// [X] Renderer: Support for large meshes (64k+ vertices) with 16-bit indices.
-
-// You can copy and use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
-// If you are new to Dear ImGui, read documentation from the docs/ folder + read the top of imgui.cpp.
-// Read online: https://github.com/ocornut/imgui/tree/master/docs
-
-// CHANGELOG
-// (minor and older changes stripped away, please see git history for details)
-// 2021-02-18: DirectX11: Change blending equation to preserve alpha in output buffer.
-// 2019-08-01: DirectX11: Fixed code querying the Geometry Shader state (would generally error with Debug layer enabled).
-// 2019-07-21: DirectX11: Backup, clear and restore Geometry Shader is any is bound when calling ImGui_ImplDX10_RenderDrawData. Clearing Hull/Domain/Compute shaders without backup/restore.
-// 2019-05-29: DirectX11: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
-// 2019-04-30: DirectX11: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
-// 2018-12-03: Misc: Added #pragma comment statement to automatically link with d3dcompiler.lib when using D3DCompile().
-// 2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
-// 2018-08-01: DirectX11: Querying for IDXGIFactory instead of IDXGIFactory1 to increase compatibility.
-// 2018-07-13: DirectX11: Fixed unreleased resources in Init and Shutdown functions.
-// 2018-06-08: Misc: Extracted imgui_impl_dx11.cpp/.h away from the old combined DX11+Win32 example.
-// 2018-06-08: DirectX11: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
-// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplDX11_RenderDrawData() in the .h file so you can call it yourself.
-// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
-// 2016-05-07: DirectX11: Disabling depth-write.

-// dear imgui: Renderer Backend for DirectX11
-// This needs to be used along with a Platform Backend (e.g. Win32)
-
-// Implemented features:
-// [X] Renderer: User texture binding. Use 'ID3D11ShaderResourceView*' as ImTextureID. Read the FAQ about ImTextureID!
-// [X] Renderer: Support for large meshes (64k+ vertices) with 16-bit indices.
-
-// You can copy and use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
-// If you are new to Dear ImGui, read documentation from the docs/ folder + read the top of imgui.cpp.

-// CHANGELOG
-// (minor and older changes stripped away, please see git history for details)
-// 2021-02-18: Added ImGui_ImplWin32_EnableAlphaCompositing(). Non Visual Studio users will need to link with dwmapi.lib (MinGW/gcc: use -ldwmapi).
-// 2021-02-17: Fixed ImGui_ImplWin32_EnableDpiAwareness() attempting to get SetProcessDpiAwareness from shcore.dll on Windows 8 whereas it is only supported on Windows 8.1.
-// 2021-01-25: Inputs: Dynamically loading XInput DLL.
-// 2020-12-04: Misc: Fixed setting of io.DisplaySize to invalid/uninitialized data when after hwnd has been closed.
-// 2020-03-03: Inputs: Calling AddInputCharacterUTF16() to support surrogate pairs leading to codepoint >= 0x10000 (for more complete CJK inputs)
-// 2020-02-17: Added ImGui_ImplWin32_EnableDpiAwareness(), ImGui_ImplWin32_GetDpiScaleForHwnd(), ImGui_ImplWin32_GetDpiScaleForMonitor() helper functions.

-// 2019-05-11: Inputs: Don't filter value from WM_CHAR before calling AddInputCharacter().
-// 2019-01-17: Misc: Using GetForegroundWindow()+IsChild() instead of GetActiveWindow() to be compatible with windows created in a different thread or parent.
-// 2019-01-17: Inputs: Added support for mouse buttons 4 and 5 via WM_XBUTTON* messages.
-// 2019-01-15: Inputs: Added support for XInput gamepads (if ImGuiConfigFlags_NavEnableGamepad is set by user application).
-// 2018-11-30: Misc: Setting up io.BackendPlatformName so it can be displayed in the About Window.
-// 2018-06-29: Inputs: Added support for the ImGuiMouseCursor_Hand cursor.
-// 2018-06-10: Inputs: Fixed handling of mouse wheel messages to support fine position messages (typically sent by track-pads).
-// 2018-06-08: Misc: Extracted imgui_impl_win32.cpp/.h away from the old combined DX9/DX10/DX11/DX12 examples.
-// 2018-03-20: Misc: Setup io.BackendFlags ImGuiBackendFlags_HasMouseCursors and ImGuiBackendFlags_HasSetMousePos flags + honor ImGuiConfigFlags_NoMouseCursorChange flag.

-// 2018-02-06: Inputs: Added mapping for ImGuiKey_Space.
-// 2018-02-06: Inputs: Honoring the io.WantSetMousePos by repositioning the mouse (when using navigation and ImGuiConfigFlags_NavMoveMouse is set).
-// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
-// 2018-01-20: Inputs: Added Horizontal Mouse Wheel support.
-// 2018-01-08: Inputs: Added mapping for ImGuiKey_Insert.
-// 2018-01-05: Inputs: Added WM_LBUTTONDBLCLK double-click handlers for window classes with the CS_DBLCLKS flag.
-// 2017-10-23: Inputs: Added WM_SYSKEYDOWN / WM_SYSKEYUP handlers so e.g. the VK_MENU key can be read.

-//#define IMGUI_API __declspec( dllexport )
-//#define IMGUI_API __declspec( dllimport )
-
-//---- Don't define obsolete functions/enums/behaviors. Consider enabling from time to time after updating to avoid using soon-to-be obsolete function/names.
-//#define IMGUI_DISABLE_OBSOLETE_FUNCTIONS
-
-//---- Disable all of Dear ImGui or don't implement standard windows.
-// It is very strongly recommended to NOT disable the demo windows during development. Please read comments in imgui_demo.cpp.
-//#define IMGUI_DISABLE // Disable everything: all headers and source files will be empty.
-//#define IMGUI_DISABLE_DEMO_WINDOWS // Disable demo windows: ShowDemoWindow()/ShowStyleEditor() will be empty. Not recommended.
-//#define IMGUI_DISABLE_METRICS_WINDOW // Disable metrics/debugger window: ShowMetricsWindow() will be empty.
-
-//---- Don't implement some functions to reduce linkage requirements.
-//#define IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCTIONS // [Win32] Don't implement default clipboard handler. Won't use and link with OpenClipboard/GetClipboardData/CloseClipboard etc. (user32.lib/.a, kernel32.lib/.a)
-//#define IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS // [Win32] Don't implement default IME handler. Won't use and link with ImmGetContext/ImmSetCompositionWindow. (imm32.lib/.a)
-//#define IMGUI_DISABLE_WIN32_FUNCTIONS // [Win32] Won't use and link with any Win32 function (clipboard, ime).
-//#define IMGUI_ENABLE_OSX_DEFAULT_CLIPBOARD_FUNCTIONS // [OSX] Implement default OSX clipboard handler (need to link with '-framework ApplicationServices', this is why this is not the default).
-//#define IMGUI_DISABLE_DEFAULT_FORMAT_FUNCTIONS // Don't implement ImFormatString/ImFormatStringV so you can implement them yourself (e.g. if you don't want to link with vsnprintf)
-//#define IMGUI_DISABLE_DEFAULT_MATH_FUNCTIONS // Don't implement ImFabs/ImSqrt/ImPow/ImFmod/ImCos/ImSin/ImAcos/ImAtan2 so you can implement them yourself.
-//#define IMGUI_DISABLE_DEFAULT_FILE_FUNCTIONS // Don't implement ImFileOpen/ImFileClose/ImFileRead/ImFileWrite so you can implement them yourself if you don't want to link with fopen/fclose/fread/fwrite. This will also disable the LogToTTY() function.
-//#define IMGUI_DISABLE_DEFAULT_ALLOCATORS // Don't implement default allocators calling malloc()/free() to avoid linking with them. You will need to call ImGui::SetAllocatorFunctions().
-
-//---- Include imgui_user.h at the end of imgui.h as a convenience
-//#define IMGUI_INCLUDE_IMGUI_USER_H
-
-//---- Pack colors to BGRA8 instead of RGBA8 (to avoid converting from one to another)
-//#define IMGUI_USE_BGRA_PACKED_COLOR
-
-//---- Use 32-bit for ImWchar (default is 16-bit) to support unicode planes 1-16. (e.g. point beyond 0xFFFF like emoticons, dingbats, symbols, shapes, ancient languages, etc...)
-//#define IMGUI_USE_WCHAR32
-
-//---- Avoid multiple STB libraries implementations, or redefine path/filenames to prioritize another version
-// By default the embedded implementations are declared static and not available outside of Dear ImGui sources files.
-//#define IMGUI_STB_TRUETYPE_FILENAME "my_folder/stb_truetype.h"
-//#define IMGUI_STB_RECT_PACK_FILENAME "my_folder/stb_rect_pack.h"
-//#define IMGUI_DISABLE_STB_TRUETYPE_IMPLEMENTATION
-//#define IMGUI_DISABLE_STB_RECT_PACK_IMPLEMENTATION
-
-//---- Use stb_printf's faster implementation of vsnprintf instead of the one from libc (unless IMGUI_DISABLE_DEFAULT_FORMAT_FUNCTIONS is defined)
-// Requires 'stb_sprintf.h' to be available in the include path. Compatibility checks of arguments and formats done by clang and GCC will be disabled in order to support the extra formats provided by STB sprintf.
-// #define IMGUI_USE_STB_SPRINTF
-
-//---- Use FreeType to build and rasterize the font atlas (instead of stb_truetype which is embedded by default in Dear ImGui)
-// Requires FreeType headers to be available in the include path. Requires program to be compiled with 'misc/freetype/imgui_freetype.cpp' (in this repository) + the FreeType library (not provided).
-// On Windows you may use vcpkg with 'vcpkg install freetype' + 'vcpkg integrate install'.
-//#define IMGUI_ENABLE_FREETYPE
-
-//---- Use stb_truetype to build and rasterize the font atlas (default)
-// The only purpose of this define is if you want force compilation of the stb_truetype backend ALONG with the FreeType backend.
-//#define IMGUI_ENABLE_STB_TRUETYPE
-
-//---- Define constructor and implicit cast operators to convert back<>forth between your math types and ImVec2/ImVec4.
-// This will be inlined as part of ImVec2 and ImVec4 class declarations.
-/*
-#define IM_VEC2_CLASS_EXTRA \
- ImVec2(const MyVec2& f) { x = f.x; y = f.y; } \

- ImVec4(const MyVec4& f) { x = f.x; y = f.y; z = f.z; w = f.w; } \
- operator MyVec4() const { return MyVec4(x,y,z,w); }
-*/
-
-//---- Use 32-bit vertex indices (default is 16-bit) is one way to allow large meshes with more than 64K vertices.
-// Your renderer backend will need to support it (most example renderer backends support both 16/32-bit indices).
-// Another way to allow large meshes while keeping 16-bit indices is to handle ImDrawCmd::VtxOffset in your renderer.
-// Read about ImGuiBackendFlags_RendererHasVtxOffset for details.
-//#define ImDrawIdx unsigned int
-
-//---- Override ImDrawCallback signature (will need to modify renderer backends accordingly)
-//struct ImDrawList;
-//struct ImDrawCmd;
-//typedef void (*MyImDrawCallback)(const ImDrawList* draw_list, const ImDrawCmd* cmd, void* my_renderer_user_data);
-//#define ImDrawCallback MyImDrawCallback
-
-//---- Debug Tools: Macro to break in Debugger
-// (use 'Metrics->Tools->Item Picker' to pick widgets with the mouse and break into them for easy debugging.)
-//#define IM_DEBUG_BREAK IM_ASSERT(0)
-//#define IM_DEBUG_BREAK __debugbreak()
-
-//---- Debug Tools: Have the Item Picker break in the ItemAdd() function instead of ItemHoverable(),
-// (which comes earlier in the code, will catch a few extra items, allow picking items other than Hovered one.)
-// This adds a small runtime cost which is why it is not enabled by default.
-//#define IMGUI_DEBUG_TOOL_ITEM_PICKER_EX
-
-//---- Debug Tools: Enable slower asserts
-//#define IMGUI_DEBUG_PARANOID
-
-//---- Tip: You can add extra functions within the ImGui:: namespace, here or in your own headers files.

- MISSION STATEMENT
- =================
-
- - Easy to use to create code-driven and data-driven tools.
- - Easy to use to create ad hoc short-lived tools and long-lived, more elaborate tools.
- - Easy to hack and improve.
- - Minimize setup and maintenance.
- - Minimize state storage on user side.
- - Portable, minimize dependencies, run on target (consoles, phones, etc.).
- - Efficient runtime and memory consumption.
-
- Designed for developers and content-creators, not the typical end-user! Some of the current weaknesses includes:
-
- - Doesn't look fancy, doesn't animate.
- - Limited layout features, intricate layouts are typically crafted in code.
-
-
- END-USER GUIDE
- ==============
-
- - Double-click on title bar to collapse window.
- - Click upper right corner to close a window, available when 'bool* p_open' is passed to ImGui::Begin().
- - Click and drag on lower right corner to resize window (double-click to auto fit window to its contents).
- - Click and drag on any empty space to move window.
- - TAB/SHIFT+TAB to cycle through keyboard editable fields.
- - CTRL+Click on a slider or drag box to input value as text.
- - Use mouse wheel to scroll.
- - Text editor:
- - Hold SHIFT or use mouse to select text.
- - CTRL+Left/Right to word jump.
- - CTRL+Shift+Left/Right to select words.
- - CTRL+A our Double-Click to select all.
- - CTRL+X,CTRL+C,CTRL+V to use OS clipboard/
- - CTRL+Z,CTRL+Y to undo/redo.
- - ESCAPE to revert text to its original value.
- - You can apply arithmetic operators +,*,/ on numerical values. Use +- to subtract (because - would set a negative value!)
- - Controls are automatically adjusted for OSX to match standard OSX text editing operations.
- - General Keyboard controls: enable with ImGuiConfigFlags_NavEnableKeyboard.
- - General Gamepad controls: enable with ImGuiConfigFlags_NavEnableGamepad. See suggested mappings in imgui.h ImGuiNavInput_ + download PNG/PSD at http://dearimgui.org/controls_sheets

- PROGRAMMER GUIDE
- ================
-
- READ FIRST
- ----------
- - Remember to read the FAQ (https://www.dearimgui.org/faq)
- - Your code creates the UI, if your code doesn't run the UI is gone! The UI can be highly dynamic, there are no construction
- or destruction steps, less superfluous data retention on your side, less state duplication, less state synchronization, less bugs.
- - Call and read ImGui::ShowDemoWindow() for demo code demonstrating most features.
- - The library is designed to be built from sources. Avoid pre-compiled binaries and packaged versions. See imconfig.h to configure your build.
- - Dear ImGui is an implementation of the IMGUI paradigm (immediate-mode graphical user interface, a term coined by Casey Muratori).
- You can learn about IMGUI principles at http://www.johno.se/book/imgui.html, http://mollyrocket.com/861 & more links in the FAQ.
- - Dear ImGui is a "single pass" rasterizing implementation of the IMGUI paradigm, aimed at ease of use and high-performances.
- For every application frame your UI code will be called only once. This is in contrast to e.g. Unity's own implementation of an IMGUI,
- where the UI code is called multiple times ("multiple passes") from a single entry point. There are pros and cons to both approaches.
- - Our origin are on the top-left. In axis aligned bounding boxes, Min = top-left, Max = bottom-right.
- - This codebase is also optimized to yield decent performances with typical "Debug" builds settings.
- - Please make sure you have asserts enabled (IM_ASSERT redirects to assert() by default, but can be redirected).
- If you get an assert, read the messages and comments around the assert.
- - C++: this is a very C-ish codebase: we don't rely on C++11, we don't include any C++ headers, and ImGui:: is a namespace.
- - C++: ImVec2/ImVec4 do not expose math operators by default, because it is expected that you use your own math types.
- See FAQ "How can I use my own math types instead of ImVec2/ImVec4?" for details about setting up imconfig.h for that.
- However, imgui_internal.h can optionally export math operators for ImVec2/ImVec4, which we use in this codebase.
- - C++: pay attention that ImVector<> manipulates plain-old-data and does not honor construction/destruction (avoid using it in your code!).
-
-
- HOW TO UPDATE TO A NEWER VERSION OF DEAR IMGUI
- ----------------------------------------------
- - Overwrite all the sources files except for imconfig.h (if you have made modification to your copy of imconfig.h)
- - Or maintain your own branch where you have imconfig.h modified as a top-most commit which you can regularly rebase over master.
- - You can also use '#define IMGUI_USER_CONFIG "my_config_file.h" to redirect configuration to your own file.
- - Read the "API BREAKING CHANGES" section (below). This is where we list occasional API breaking changes.
- If a function/type has been renamed / or marked obsolete, try to fix the name in your code before it is permanently removed
- from the public API. If you have a problem with a missing function/symbols, search for its name in the code, there will
- likely be a comment about it. Please report any issue to the GitHub page!
- - To find out usage of old API, you can add '#define IMGUI_DISABLE_OBSOLETE_FUNCTIONS' in your configuration file.
- - Try to keep your copy of Dear ImGui reasonably up to date.
-
-
- GETTING STARTED WITH INTEGRATING DEAR IMGUI IN YOUR CODE/ENGINE
- ---------------------------------------------------------------
- - Run and study the examples and demo in imgui_demo.cpp to get acquainted with the library.
- - In the majority of cases you should be able to use unmodified backends files available in the backends/ folder.
- - Add the Dear ImGui source files + selected backend source files to your projects or using your preferred build system.
- It is recommended you build and statically link the .cpp files as part of your project and NOT as shared library (DLL).
- - You can later customize the imconfig.h file to tweak some compile-time behavior, such as integrating Dear ImGui types with your own maths types.
- - When using Dear ImGui, your programming IDE is your friend: follow the declaration of variables, functions and types to find comments about them.
- - Dear ImGui never touches or knows about your GPU state. The only function that knows about GPU is the draw function that you provide.
- Effectively it means you can create widgets at any time in your code, regardless of considerations of being in "update" vs "render"
- phases of your own application. All rendering information are stored into command-lists that you will retrieve after calling ImGui::Render().
- - Refer to the backends and demo applications in the examples/ folder for instruction on how to setup your code.
- - If you are running over a standard OS with a common graphics API, you should be able to use unmodified imgui_impl_*** files from the examples/ folder.
-
-
- HOW A SIMPLE APPLICATION MAY LOOK LIKE
- --------------------------------------
- EXHIBIT 1: USING THE EXAMPLE BACKENDS (= imgui_impl_XXX.cpp files from the backends/ folder).
- The sub-folders in examples/ contains examples applications following this structure.
-
- // Application init: create a dear imgui context, setup some options, load fonts
- ImGui::CreateContext();
- ImGuiIO& io = ImGui::GetIO();
- // TODO: Set optional io.ConfigFlags values, e.g. 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard' to enable keyboard controls.
- // TODO: Fill optional fields of the io structure later.
- // TODO: Load TTF/OTF fonts if you don't want to use the default font.
-
- // Initialize helper Platform and Renderer backends (here we are using imgui_impl_win32.cpp and imgui_impl_dx11.cpp)
- ImGui_ImplWin32_Init(hwnd);
- ImGui_ImplDX11_Init(g_pd3dDevice, g_pd3dDeviceContext);
-
- // Application main loop
- while (true)
- {
- // Feed inputs to dear imgui, start new frame
- ImGui_ImplDX11_NewFrame();
- ImGui_ImplWin32_NewFrame();
- ImGui::NewFrame();
-
- // Any application code here
- ImGui::Text("Hello, world!");
-
- // Render dear imgui into screen
- ImGui::Render();
- ImGui_ImplDX11_RenderDrawData(ImGui::GetDrawData());
- g_pSwapChain->Present(1, 0);
- }
-
- // Shutdown
- ImGui_ImplDX11_Shutdown();
- ImGui_ImplWin32_Shutdown();
- ImGui::DestroyContext();
-
- EXHIBIT 2: IMPLEMENTING CUSTOM BACKEND / CUSTOM ENGINE
-
- // Application init: create a dear imgui context, setup some options, load fonts
- ImGui::CreateContext();
- ImGuiIO& io = ImGui::GetIO();
- // TODO: Set optional io.ConfigFlags values, e.g. 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard' to enable keyboard controls.
- // TODO: Fill optional fields of the io structure later.
- // TODO: Load TTF/OTF fonts if you don't want to use the default font.
-
- // Build and load the texture atlas into a texture
- // (In the examples/ app this is usually done within the ImGui_ImplXXX_Init() function from one of the demo Renderer)
- int width, height;
- unsigned char* pixels = NULL;
- io.Fonts->GetTexDataAsRGBA32(&pixels, &width, &height);
-
- // At this point you've got the texture data and you need to upload that your your graphic system:
- // After we have created the texture, store its pointer/identifier (_in whichever format your engine uses_) in 'io.Fonts->TexID'.
- // This will be passed back to your via the renderer. Basically ImTextureID == void*. Read FAQ for details about ImTextureID.
- MyTexture* texture = MyEngine::CreateTextureFromMemoryPixels(pixels, width, height, TEXTURE_TYPE_RGBA32)
- io.Fonts->SetTexID((void*)texture);
-
- // Application main loop
- while (true)
- {
- // Setup low-level inputs, e.g. on Win32: calling GetKeyboardState(), or write to those fields from your Windows message handlers, etc.
- // (In the examples/ app this is usually done within the ImGui_ImplXXX_NewFrame() function from one of the demo Platform Backends)
- io.DeltaTime = 1.0f/60.0f; // set the time elapsed since the previous frame (in seconds)
- io.DisplaySize.x = 1920.0f; // set the current display width
- io.DisplaySize.y = 1280.0f; // set the current display height here
- io.MousePos = my_mouse_pos; // set the mouse position
- io.MouseDown[0] = my_mouse_buttons[0]; // set the mouse button states
- io.MouseDown[1] = my_mouse_buttons[1];
-
- // Call NewFrame(), after this point you can use ImGui::* functions anytime
- // (So you want to try calling NewFrame() as early as you can in your mainloop to be able to use Dear ImGui everywhere)
- ImGui::NewFrame();
-
- // Most of your application code here
- ImGui::Text("Hello, world!");
- MyGameUpdate(); // may use any Dear ImGui functions, e.g. ImGui::Begin("My window"); ImGui::Text("Hello, world!"); ImGui::End();
- MyGameRender(); // may use any Dear ImGui functions as well!
-
- // Render dear imgui, swap buffers
- // (You want to try calling EndFrame/Render as late as you can, to be able to use Dear ImGui in your own game rendering code)
- ImGui::EndFrame();
- ImGui::Render();
- ImDrawData* draw_data = ImGui::GetDrawData();
- MyImGuiRenderFunction(draw_data);
- SwapBuffers();
- }
-
- // Shutdown
- ImGui::DestroyContext();
-
- To decide whether to dispatch mouse/keyboard inputs to Dear ImGui to the rest your application,
- you should read the 'io.WantCaptureMouse', 'io.WantCaptureKeyboard' and 'io.WantTextInput' flags!
- Please read the FAQ and example applications for details about this!
-
-
- HOW A SIMPLE RENDERING FUNCTION MAY LOOK LIKE
- ---------------------------------------------
- The backends in impl_impl_XXX.cpp files contains many working implementations of a rendering function.
-
- void void MyImGuiRenderFunction(ImDrawData* draw_data)
- {
- // TODO: Setup render state: alpha-blending enabled, no face culling, no depth testing, scissor enabled
- // TODO: Setup viewport covering draw_data->DisplayPos to draw_data->DisplayPos + draw_data->DisplaySize
- // TODO: Setup orthographic projection matrix cover draw_data->DisplayPos to draw_data->DisplayPos + draw_data->DisplaySize
- // TODO: Setup shader: vertex { float2 pos, float2 uv, u32 color }, fragment shader sample color from 1 texture, multiply by vertex color.
- for (int n = 0; n < draw_data->CmdListsCount; n++)
- {
- const ImDrawList* cmd_list = draw_data->CmdLists[n];
- const ImDrawVert* vtx_buffer = cmd_list->VtxBuffer.Data; // vertex buffer generated by Dear ImGui
- const ImDrawIdx* idx_buffer = cmd_list->IdxBuffer.Data; // index buffer generated by Dear ImGui
- for (int cmd_i = 0; cmd_i < cmd_list->CmdBuffer.Size; cmd_i++)
- {
- const ImDrawCmd* pcmd = &cmd_list->CmdBuffer[cmd_i];
- if (pcmd->UserCallback)
- {
- pcmd->UserCallback(cmd_list, pcmd);
- }
- else
- {
- // The texture for the draw call is specified by pcmd->TextureId.
- // The vast majority of draw calls will use the Dear ImGui texture atlas, which value you have set yourself during initialization.
- MyEngineBindTexture((MyTexture*)pcmd->TextureId);
-
- // We are using scissoring to clip some objects. All low-level graphics API should supports it.
- // - If your engine doesn't support scissoring yet, you may ignore this at first. You will get some small glitches
- // (some elements visible outside their bounds) but you can fix that once everything else works!
- // - Clipping coordinates are provided in imgui coordinates space:
- // - For a given viewport, draw_data->DisplayPos == viewport->Pos and draw_data->DisplaySize == viewport->Size
- // - In a single viewport application, draw_data->DisplayPos == (0,0) and draw_data->DisplaySize == io.DisplaySize, but always use GetMainViewport()->Pos/Size instead of hardcoding those values.
- // - In the interest of supporting multi-viewport applications (see 'docking' branch on github),
- // always subtract draw_data->DisplayPos from clipping bounds to convert them to your viewport space.
- // - Note that pcmd->ClipRect contains Min+Max bounds. Some graphics API may use Min+Max, other may use Min+Size (size being Max-Min)
- ImVec2 pos = draw_data->DisplayPos;
- MyEngineScissor((int)(pcmd->ClipRect.x - pos.x), (int)(pcmd->ClipRect.y - pos.y), (int)(pcmd->ClipRect.z - pos.x), (int)(pcmd->ClipRect.w - pos.y));
-
- // Render 'pcmd->ElemCount/3' indexed triangles.
- // By default the indices ImDrawIdx are 16-bit, you can change them to 32-bit in imconfig.h if your engine doesn't support 16-bit indices.
- MyEngineDrawIndexedTriangles(pcmd->ElemCount, sizeof(ImDrawIdx) == 2 ? GL_UNSIGNED_SHORT : GL_UNSIGNED_INT, idx_buffer, vtx_buffer);
- }
- idx_buffer += pcmd->ElemCount;
- }
- }
- }
-
-
- USING GAMEPAD/KEYBOARD NAVIGATION CONTROLS
- ------------------------------------------
- - The gamepad/keyboard navigation is fairly functional and keeps being improved.
- - Gamepad support is particularly useful to use Dear ImGui on a console system (e.g. PS4, Switch, XB1) without a mouse!
- - You can ask questions and report issues at https://github.com/ocornut/imgui/issues/787
- - The initial focus was to support game controllers, but keyboard is becoming increasingly and decently usable.
- - Keyboard:
- - Set io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard to enable.
- NewFrame() will automatically fill io.NavInputs[] based on your io.KeysDown[] + io.KeyMap[] arrays.
- - When keyboard navigation is active (io.NavActive + ImGuiConfigFlags_NavEnableKeyboard), the io.WantCaptureKeyboard flag
- will be set. For more advanced uses, you may want to read from:
- - io.NavActive: true when a window is focused and it doesn't have the ImGuiWindowFlags_NoNavInputs flag set.
- - io.NavVisible: true when the navigation cursor is visible (and usually goes false when mouse is used).
- - or query focus information with e.g. IsWindowFocused(ImGuiFocusedFlags_AnyWindow), IsItemFocused() etc. functions.
- Please reach out if you think the game vs navigation input sharing could be improved.
- - Gamepad:
- - Set io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad to enable.
- - Backend: Set io.BackendFlags |= ImGuiBackendFlags_HasGamepad + fill the io.NavInputs[] fields before calling NewFrame().
- Note that io.NavInputs[] is cleared by EndFrame().
- - See 'enum ImGuiNavInput_' in imgui.h for a description of inputs. For each entry of io.NavInputs[], set the following values:
- 0.0f= not held. 1.0f= fully held. Pass intermediate 0.0f..1.0f values for analog triggers/sticks.
- - We uses a simple >0.0f test for activation testing, and won't attempt to test for a dead-zone.
- Your code will probably need to transform your raw inputs (such as e.g. remapping your 0.2..0.9 raw input range to 0.0..1.0 imgui range, etc.).
- - You can download PNG/PSD files depicting the gamepad controls for common controllers at: http://dearimgui.org/controls_sheets
- - If you need to share inputs between your game and the imgui parts, the easiest approach is to go all-or-nothing, with a buttons combo
- to toggle the target. Please reach out if you think the game vs navigation input sharing could be improved.
- - Mouse:
- - PS4 users: Consider emulating a mouse cursor with DualShock4 touch pad or a spare analog stick as a mouse-emulation fallback.
- - Consoles/Tablet/Phone users: Consider using a Synergy 1.x server (on your PC) + uSynergy.c (on your console/tablet/phone app) to share your PC mouse/keyboard.
- - On a TV/console system where readability may be lower or mouse inputs may be awkward, you may want to set the ImGuiConfigFlags_NavEnableSetMousePos flag.
- Enabling ImGuiConfigFlags_NavEnableSetMousePos + ImGuiBackendFlags_HasSetMousePos instructs dear imgui to move your mouse cursor along with navigation movements.
- When enabled, the NewFrame() function may alter 'io.MousePos' and set 'io.WantSetMousePos' to notify you that it wants the mouse cursor to be moved.
- When that happens your backend NEEDS to move the OS or underlying mouse cursor on the next frame. Some of the backends in examples/ do that.
- (If you set the NavEnableSetMousePos flag but don't honor 'io.WantSetMousePos' properly, imgui will misbehave as it will see your mouse as moving back and forth!)
- (In a setup when you may not have easy control over the mouse cursor, e.g. uSynergy.c doesn't expose moving remote mouse cursor, you may want
- to set a boolean to ignore your other external mouse positions until the external source is moved again.)

- API BREAKING CHANGES
- ====================
-
- Occasionally introducing changes that are breaking the API. We try to make the breakage minor and easy to fix.
- Below is a change-log of API breaking changes only. If you are using one of the functions listed, expect to have to fix some code.
- When you are not sure about a old symbol or function name, try using the Search/Find function of your IDE to look for comments or references in all imgui files.
- You can read releases logs https://github.com/ocornut/imgui/releases for more details.
-
- - 2021/03/10 (1.82) - upgraded ImDrawList::AddPolyline() and PathStroke() "bool closed" parameter to "ImDrawFlags flags". The matching ImDrawFlags_Closed value is guaranteed to always stay == 1 in the future.
- - 2021/02/22 (1.82) - win32+mingw: Re-enabled IME functions by default even under MinGW. In July 2016, issue #738 had me incorrectly disable those default functions for MinGW. MinGW users should: either link with -limm32, either set their imconfig file with '#define IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS'.
- - 2021/02/17 (1.82) - renamed rarely used style.CircleSegmentMaxError (old default = 1.60f) to style.CircleTessellationMaxError (new default = 0.30f) as the meaning of the value changed.
- - 2021/02/03 (1.81) - renamed ListBoxHeader(const char* label, ImVec2 size) to BeginListBox(). Kept inline redirection function (will obsolete).
- - removed ListBoxHeader(const char* label, int items_count, int height_in_items = -1) in favor of specifying size. Kept inline redirection function (will obsolete).
- - renamed ListBoxFooter() to EndListBox(). Kept inline redirection function (will obsolete).
- - 2021/01/26 (1.81) - removed ImGuiFreeType::BuildFontAtlas(). Kept inline redirection function. Prefer using '#define IMGUI_ENABLE_FREETYPE', but there's a runtime selection path available too. The shared extra flags parameters (very rarely used) are now stored in ImFontAtlas::FontBuilderFlags.
- - renamed ImFontConfig::RasterizerFlags (used by FreeType) to ImFontConfig::FontBuilderFlags.
- - renamed ImGuiFreeType::XXX flags to ImGuiFreeTypeBuilderFlags_XXX for consistency with other API.
- - 2020/10/12 (1.80) - removed redirecting functions/enums that were marked obsolete in 1.63 (August 2018):
- - ImGui::IsItemDeactivatedAfterChange() -> use ImGui::IsItemDeactivatedAfterEdit().
- - ImGuiCol_ModalWindowDarkening -> use ImGuiCol_ModalWindowDimBg
- - ImGuiInputTextCallback -> use ImGuiTextEditCallback
- - ImGuiInputTextCallbackData -> use ImGuiTextEditCallbackData
- - 2020/12/21 (1.80) - renamed ImDrawList::AddBezierCurve() to AddBezierCubic(), and PathBezierCurveTo() to PathBezierCubicCurveTo(). Kept inline redirection function (will obsolete).
- - 2020/12/04 (1.80) - added imgui_tables.cpp file! Manually constructed project files will need the new file added!
- - 2020/11/18 (1.80) - renamed undocumented/internals ImGuiColumnsFlags_* to ImGuiOldColumnFlags_* in prevision of incoming Tables API.
- - 2020/11/03 (1.80) - renamed io.ConfigWindowsMemoryCompactTimer to io.ConfigMemoryCompactTimer as the feature will apply to other data structures
- - 2020/10/14 (1.80) - backends: moved all backends files (imgui_impl_XXXX.cpp, imgui_impl_XXXX.h) from examples/ to backends/.
- - 2020/10/12 (1.80) - removed redirecting functions/enums that were marked obsolete in 1.60 (April 2018):
- - io.RenderDrawListsFn pointer -> use ImGui::GetDrawData() value and call the render function of your backend
- - ImGui::IsAnyWindowFocused() -> use ImGui::IsWindowFocused(ImGuiFocusedFlags_AnyWindow)
- - ImGui::IsAnyWindowHovered() -> use ImGui::IsWindowHovered(ImGuiHoveredFlags_AnyWindow)
- - ImGuiStyleVar_Count_ -> use ImGuiStyleVar_COUNT
- - ImGuiMouseCursor_Count_ -> use ImGuiMouseCursor_COUNT
- - removed redirecting functions names that were marked obsolete in 1.61 (May 2018):
- - InputFloat (... int decimal_precision ...) -> use InputFloat (... const char* format ...) with format = "%.Xf" where X is your value for decimal_precision.
- - same for InputFloat2()/InputFloat3()/InputFloat4() variants taking a `int decimal_precision` parameter.
- - 2020/10/05 (1.79) - removed ImGuiListClipper: Renamed constructor parameters which created an ambiguous alternative to using the ImGuiListClipper::Begin() function, with misleading edge cases (note: imgui_memory_editor <0.40 from imgui_club/ used this old clipper API. Update your copy if needed).
- - 2020/09/25 (1.79) - renamed ImGuiSliderFlags_ClampOnInput to ImGuiSliderFlags_AlwaysClamp. Kept redirection enum (will obsolete sooner because previous name was added recently).
- - 2020/09/25 (1.79) - renamed style.TabMinWidthForUnselectedCloseButton to style.TabMinWidthForCloseButton.
- - 2020/09/21 (1.79) - renamed OpenPopupContextItem() back to OpenPopupOnItemClick(), reverting the change from 1.77. For varieties of reason this is more self-explanatory.
- - 2020/09/21 (1.79) - removed return value from OpenPopupOnItemClick() - returned true on mouse release on item - because it is inconsistent with other popup APIs and makes others misleading. It's also and unnecessary: you can use IsWindowAppearing() after BeginPopup() for a similar result.
- - 2020/09/17 (1.79) - removed ImFont::DisplayOffset in favor of ImFontConfig::GlyphOffset. DisplayOffset was applied after scaling and not very meaningful/useful outside of being needed by the default ProggyClean font. If you scaled this value after calling AddFontDefault(), this is now done automatically. It was also getting in the way of better font scaling, so let's get rid of it now!
- - 2020/08/17 (1.78) - obsoleted use of the trailing 'float power=1.0f' parameter for DragFloat(), DragFloat2(), DragFloat3(), DragFloat4(), DragFloatRange2(), DragScalar(), DragScalarN(), SliderFloat(), SliderFloat2(), SliderFloat3(), SliderFloat4(), SliderScalar(), SliderScalarN(), VSliderFloat() and VSliderScalar().
- replaced the 'float power=1.0f' argument with integer-based flags defaulting to 0 (as with all our flags).
- worked out a backward-compatibility scheme so hopefully most C++ codebase should not be affected. in short, when calling those functions:
- - if you omitted the 'power' parameter (likely!), you are not affected.
- - if you set the 'power' parameter to 1.0f (same as previous default value): 1/ your compiler may warn on float>int conversion, 2/ everything else will work. 3/ you can replace the 1.0f value with 0 to fix the warning, and be technically correct.
- - if you set the 'power' parameter to >1.0f (to enable non-linear editing): 1/ your compiler may warn on float>int conversion, 2/ code will assert at runtime, 3/ in case asserts are disabled, the code will not crash and enable the _Logarithmic flag. 4/ you can replace the >1.0f value with ImGuiSliderFlags_Logarithmic to fix the warning/assert and get a _similar_ effect as previous uses of power >1.0f.
- see https://github.com/ocornut/imgui/issues/3361 for all details.
- kept inline redirection functions (will obsolete) apart for: DragFloatRange2(), VSliderFloat(), VSliderScalar(). For those three the 'float power=1.0f' version were removed directly as they were most unlikely ever used.
- for shared code, you can version check at compile-time with `#if IMGUI_VERSION_NUM >= 17704`.
- - obsoleted use of v_min > v_max in DragInt, DragFloat, DragScalar to lock edits (introduced in 1.73, was not demoed nor documented very), will be replaced by a more generic ReadOnly feature. You may use the ImGuiSliderFlags_ReadOnly internal flag in the meantime.
- - 2020/06/23 (1.77) - removed BeginPopupContextWindow(const char*, int mouse_button, bool also_over_items) in favor of BeginPopupContextWindow(const char*, ImGuiPopupFlags flags) with ImGuiPopupFlags_NoOverItems.
- - 2020/06/15 (1.77) - renamed OpenPopupOnItemClick() to OpenPopupContextItem(). Kept inline redirection function (will obsolete). [NOTE: THIS WAS REVERTED IN 1.79]
- - 2020/06/15 (1.77) - removed CalcItemRectClosestPoint() entry point which was made obsolete and asserting in December 2017.
- - 2020/04/23 (1.77) - removed unnecessary ID (first arg) of ImFontAtlas::AddCustomRectRegular().
- - 2020/01/22 (1.75) - ImDrawList::AddCircle()/AddCircleFilled() functions don't accept negative radius any more.
- - 2019/12/17 (1.75) - [undid this change in 1.76] made Columns() limited to 64 columns by asserting above that limit. While the current code technically supports it, future code may not so we're putting the restriction ahead.
- - 2019/12/13 (1.75) - [imgui_internal.h] changed ImRect() default constructor initializes all fields to 0.0f instead of (FLT_MAX,FLT_MAX,-FLT_MAX,-FLT_MAX). If you used ImRect::Add() to create bounding boxes by adding multiple points into it, you may need to fix your initial value.
- - 2019/12/08 (1.75) - removed redirecting functions/enums that were marked obsolete in 1.53 (December 2017):
- - ShowTestWindow() -> use ShowDemoWindow()
- - IsRootWindowFocused() -> use IsWindowFocused(ImGuiFocusedFlags_RootWindow)
- - IsRootWindowOrAnyChildFocused() -> use IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows)
- - SetNextWindowContentWidth(w) -> use SetNextWindowContentSize(ImVec2(w, 0.0f)
- - GetItemsLineHeightWithSpacing() -> use GetFrameHeightWithSpacing()
- - ImGuiCol_ChildWindowBg -> use ImGuiCol_ChildBg
- - ImGuiStyleVar_ChildWindowRounding -> use ImGuiStyleVar_ChildRounding
- - ImGuiTreeNodeFlags_AllowOverlapMode -> use ImGuiTreeNodeFlags_AllowItemOverlap
- - IMGUI_DISABLE_TEST_WINDOWS -> use IMGUI_DISABLE_DEMO_WINDOWS
- - 2019/12/08 (1.75) - obsoleted calling ImDrawList::PrimReserve() with a negative count (which was the vaguely documented and rarely if ever used). Instead we added an explicit PrimUnreserve() API.
- - 2019/12/06 (1.75) - removed implicit default parameter to IsMouseDragging(int button = 0) to be consistent with other mouse functions (none of the other functions have it).
- - 2019/11/21 (1.74) - ImFontAtlas::AddCustomRectRegular() now requires an ID larger than 0x110000 (instead of 0x10000) to conform with supporting Unicode planes 1-16 in a future update. ID below 0x110000 will now assert.
- - 2019/11/19 (1.74) - renamed IMGUI_DISABLE_FORMAT_STRING_FUNCTIONS to IMGUI_DISABLE_DEFAULT_FORMAT_FUNCTIONS for consistency.
- - 2019/11/19 (1.74) - renamed IMGUI_DISABLE_MATH_FUNCTIONS to IMGUI_DISABLE_DEFAULT_MATH_FUNCTIONS for consistency.
- - 2019/10/22 (1.74) - removed redirecting functions/enums that were marked obsolete in 1.52 (October 2017):
- - Begin() [old 5 args version] -> use Begin() [3 args], use SetNextWindowSize() SetNextWindowBgAlpha() if needed
- - IsRootWindowOrAnyChildHovered() -> use IsWindowHovered(ImGuiHoveredFlags_RootAndChildWindows)
- - AlignFirstTextHeightToWidgets() -> use AlignTextToFramePadding()
- - SetNextWindowPosCenter() -> use SetNextWindowPos() with a pivot of (0.5f, 0.5f)
- - ImFont::Glyph -> use ImFontGlyph
- - 2019/10/14 (1.74) - inputs: Fixed a miscalculation in the keyboard/mouse "typematic" repeat delay/rate calculation, used by keys and e.g. repeating mouse buttons as well as the GetKeyPressedAmount() function.
- if you were using a non-default value for io.KeyRepeatRate (previous default was 0.250), you can add +io.KeyRepeatDelay to it to compensate for the fix.
- The function was triggering on: 0.0 and (delay+rate*N) where (N>=1). Fixed formula responds to (N>=0). Effectively it made io.KeyRepeatRate behave like it was set to (io.KeyRepeatRate + io.KeyRepeatDelay).
- If you never altered io.KeyRepeatRate nor used GetKeyPressedAmount() this won't affect you.
- - 2019/07/15 (1.72) - removed TreeAdvanceToLabelPos() which is rarely used and only does SetCursorPosX(GetCursorPosX() + GetTreeNodeToLabelSpacing()). Kept redirection function (will obsolete).
- - 2019/07/12 (1.72) - renamed ImFontAtlas::CustomRect to ImFontAtlasCustomRect. Kept redirection typedef (will obsolete).
- - 2019/06/14 (1.72) - removed redirecting functions/enums names that were marked obsolete in 1.51 (June 2017): ImGuiCol_Column*, ImGuiSetCond_*, IsItemHoveredRect(), IsPosHoveringAnyWindow(), IsMouseHoveringAnyWindow(), IsMouseHoveringWindow(), IMGUI_ONCE_UPON_A_FRAME. Grep this log for details and new names, or see how they were implemented until 1.71.
- - 2019/06/07 (1.71) - rendering of child window outer decorations (bg color, border, scrollbars) is now performed as part of the parent window. If you have
- overlapping child windows in a same parent, and relied on their relative z-order to be mapped to their submission order, this will affect your rendering.
- This optimization is disabled if the parent window has no visual output, because it appears to be the most common situation leading to the creation of overlapping child windows.
- Please reach out if you are affected.
- - 2019/05/13 (1.71) - renamed SetNextTreeNodeOpen() to SetNextItemOpen(). Kept inline redirection function (will obsolete).
- - 2019/05/11 (1.71) - changed io.AddInputCharacter(unsigned short c) signature to io.AddInputCharacter(unsigned int c).
- - 2019/04/29 (1.70) - improved ImDrawList thick strokes (>1.0f) preserving correct thickness up to 90 degrees angles (e.g. rectangles). If you have custom rendering using thick lines, they will appear thicker now.
- - 2019/04/29 (1.70) - removed GetContentRegionAvailWidth(), use GetContentRegionAvail().x instead. Kept inline redirection function (will obsolete).
- - 2019/03/04 (1.69) - renamed GetOverlayDrawList() to GetForegroundDrawList(). Kept redirection function (will obsolete).
- - 2019/02/26 (1.69) - renamed ImGuiColorEditFlags_RGB/ImGuiColorEditFlags_HSV/ImGuiColorEditFlags_HEX to ImGuiColorEditFlags_DisplayRGB/ImGuiColorEditFlags_DisplayHSV/ImGuiColorEditFlags_DisplayHex. Kept redirection enums (will obsolete).
- - 2019/02/14 (1.68) - made it illegal/assert when io.DisplayTime == 0.0f (with an exception for the first frame). If for some reason your time step calculation gives you a zero value, replace it with an arbitrary small value!
- - 2019/02/01 (1.68) - removed io.DisplayVisibleMin/DisplayVisibleMax (which were marked obsolete and removed from viewport/docking branch already).
- - 2019/01/06 (1.67) - renamed io.InputCharacters[], marked internal as was always intended. Please don't access directly, and use AddInputCharacter() instead!
- - 2019/01/06 (1.67) - renamed ImFontAtlas::GlyphRangesBuilder to ImFontGlyphRangesBuilder. Kept redirection typedef (will obsolete).
- - 2018/12/20 (1.67) - made it illegal to call Begin("") with an empty string. This somehow half-worked before but had various undesirable side-effects.
- - 2018/12/10 (1.67) - renamed io.ConfigResizeWindowsFromEdges to io.ConfigWindowsResizeFromEdges as we are doing a large pass on configuration flags.
- - 2018/10/12 (1.66) - renamed misc/stl/imgui_stl.* to misc/cpp/imgui_stdlib.* in prevision for other C++ helper files.
- - 2018/09/28 (1.66) - renamed SetScrollHere() to SetScrollHereY(). Kept redirection function (will obsolete).
- - 2018/09/06 (1.65) - renamed stb_truetype.h to imstb_truetype.h, stb_textedit.h to imstb_textedit.h, and stb_rect_pack.h to imstb_rectpack.h.
- If you were conveniently using the imgui copy of those STB headers in your project you will have to update your include paths.
- - 2018/09/05 (1.65) - renamed io.OptCursorBlink/io.ConfigCursorBlink to io.ConfigInputTextCursorBlink. (#1427)
- - 2018/08/31 (1.64) - added imgui_widgets.cpp file, extracted and moved widgets code out of imgui.cpp into imgui_widgets.cpp. Re-ordered some of the code remaining in imgui.cpp.
- NONE OF THE FUNCTIONS HAVE CHANGED. THE CODE IS SEMANTICALLY 100% IDENTICAL, BUT _EVERY_ FUNCTION HAS BEEN MOVED.
- Because of this, any local modifications to imgui.cpp will likely conflict when you update. Read docs/CHANGELOG.txt for suggestions.
- - 2018/08/22 (1.63) - renamed IsItemDeactivatedAfterChange() to IsItemDeactivatedAfterEdit() for consistency with new IsItemEdited() API. Kept redirection function (will obsolete soonish as IsItemDeactivatedAfterChange() is very recent).
- - 2018/08/21 (1.63) - renamed ImGuiTextEditCallback to ImGuiInputTextCallback, ImGuiTextEditCallbackData to ImGuiInputTextCallbackData for consistency. Kept redirection types (will obsolete).
- - 2018/08/21 (1.63) - removed ImGuiInputTextCallbackData::ReadOnly since it is a duplication of (ImGuiInputTextCallbackData::Flags & ImGuiInputTextFlags_ReadOnly).
- - 2018/08/01 (1.63) - removed per-window ImGuiWindowFlags_ResizeFromAnySide beta flag in favor of a global io.ConfigResizeWindowsFromEdges [update 1.67 renamed to ConfigWindowsResizeFromEdges] to enable the feature.
- - 2018/08/01 (1.63) - renamed io.OptCursorBlink to io.ConfigCursorBlink [-> io.ConfigInputTextCursorBlink in 1.65], io.OptMacOSXBehaviors to ConfigMacOSXBehaviors for consistency.
- - 2018/07/22 (1.63) - changed ImGui::GetTime() return value from float to double to avoid accumulating floating point imprecisions over time.
- - 2018/07/08 (1.63) - style: renamed ImGuiCol_ModalWindowDarkening to ImGuiCol_ModalWindowDimBg for consistency with other features. Kept redirection enum (will obsolete).
- - 2018/06/08 (1.62) - examples: the imgui_impl_XXX files have been split to separate platform (Win32, GLFW, SDL2, etc.) from renderer (DX11, OpenGL, Vulkan, etc.).
- old backends will still work as is, however prefer using the separated backends as they will be updated to support multi-viewports.
- when adopting new backends follow the main.cpp code of your preferred examples/ folder to know which functions to call.
- in particular, note that old backends called ImGui::NewFrame() at the end of their ImGui_ImplXXXX_NewFrame() function.
- - 2018/06/06 (1.62) - renamed GetGlyphRangesChinese() to GetGlyphRangesChineseFull() to distinguish other variants and discourage using the full set.
- - 2018/06/06 (1.62) - TreeNodeEx()/TreeNodeBehavior(): the ImGuiTreeNodeFlags_CollapsingHeader helper now include the ImGuiTreeNodeFlags_NoTreePushOnOpen flag. See Changelog for details.
- - 2018/05/03 (1.61) - DragInt(): the default compile-time format string has been changed from "%.0f" to "%d", as we are not using integers internally any more.
- If you used DragInt() with custom format strings, make sure you change them to use %d or an integer-compatible format.
- To honor backward-compatibility, the DragInt() code will currently parse and modify format strings to replace %*f with %d, giving time to users to upgrade their code.
- If you have IMGUI_DISABLE_OBSOLETE_FUNCTIONS enabled, the code will instead assert! You may run a reg-exp search on your codebase for e.g. "DragInt.*%f" to help you find them.
- - 2018/04/28 (1.61) - obsoleted InputFloat() functions taking an optional "int decimal_precision" in favor of an equivalent and more flexible "const char* format",
- consistent with other functions. Kept redirection functions (will obsolete).
- - 2018/04/09 (1.61) - IM_DELETE() helper function added in 1.60 doesn't clear the input _pointer_ reference, more consistent with expectation and allows passing r-value.
- - 2018/03/20 (1.60) - renamed io.WantMoveMouse to io.WantSetMousePos for consistency and ease of understanding (was added in 1.52, _not_ used by core and only honored by some backend ahead of merging the Nav branch).
- - 2018/03/12 (1.60) - removed ImGuiCol_CloseButton, ImGuiCol_CloseButtonActive, ImGuiCol_CloseButtonHovered as the closing cross uses regular button colors now.
- - 2018/03/08 (1.60) - changed ImFont::DisplayOffset.y to default to 0 instead of +1. Fixed rounding of Ascent/Descent to match TrueType renderer. If you were adding or subtracting to ImFont::DisplayOffset check if your fonts are correctly aligned vertically.
- - 2018/03/03 (1.60) - renamed ImGuiStyleVar_Count_ to ImGuiStyleVar_COUNT and ImGuiMouseCursor_Count_ to ImGuiMouseCursor_COUNT for consistency with other public enums.
- - 2018/02/18 (1.60) - BeginDragDropSource(): temporarily removed the optional mouse_button=0 parameter because it is not really usable in many situations at the moment.
- - 2018/02/16 (1.60) - obsoleted the io.RenderDrawListsFn callback, you can call your graphics engine render function after ImGui::Render(). Use ImGui::GetDrawData() to retrieve the ImDrawData* to display.
- - 2018/02/07 (1.60) - reorganized context handling to be more explicit,
- - YOU NOW NEED TO CALL ImGui::CreateContext() AT THE BEGINNING OF YOUR APP, AND CALL ImGui::DestroyContext() AT THE END.
- - removed Shutdown() function, as DestroyContext() serve this purpose.
- - you may pass a ImFontAtlas* pointer to CreateContext() to share a font atlas between contexts. Otherwise CreateContext() will create its own font atlas instance.
- - removed allocator parameters from CreateContext(), they are now setup with SetAllocatorFunctions(), and shared by all contexts.
- - removed the default global context and font atlas instance, which were confusing for users of DLL reloading and users of multiple contexts.
- - 2018/01/31 (1.60) - moved sample TTF files from extra_fonts/ to misc/fonts/. If you loaded files directly from the imgui repo you may need to update your paths.
- - 2018/01/11 (1.60) - obsoleted IsAnyWindowHovered() in favor of IsWindowHovered(ImGuiHoveredFlags_AnyWindow). Kept redirection function (will obsolete).
- - 2018/01/11 (1.60) - obsoleted IsAnyWindowFocused() in favor of IsWindowFocused(ImGuiFocusedFlags_AnyWindow). Kept redirection function (will obsolete).
- - 2018/01/03 (1.60) - renamed ImGuiSizeConstraintCallback to ImGuiSizeCallback, ImGuiSizeConstraintCallbackData to ImGuiSizeCallbackData.
- - 2017/12/29 (1.60) - removed CalcItemRectClosestPoint() which was weird and not really used by anyone except demo code. If you need it it's easy to replicate on your side.
- - 2017/12/24 (1.53) - renamed the emblematic ShowTestWindow() function to ShowDemoWindow(). Kept redirection function (will obsolete).
- - 2017/12/21 (1.53) - ImDrawList: renamed style.AntiAliasedShapes to style.AntiAliasedFill for consistency and as a way to explicitly break code that manipulate those flag at runtime. You can now manipulate ImDrawList::Flags
- - 2017/12/21 (1.53) - ImDrawList: removed 'bool anti_aliased = true' final parameter of ImDrawList::AddPolyline() and ImDrawList::AddConvexPolyFilled(). Prefer manipulating ImDrawList::Flags if you need to toggle them during the frame.
- - 2017/12/14 (1.53) - using the ImGuiWindowFlags_NoScrollWithMouse flag on a child window forwards the mouse wheel event to the parent window, unless either ImGuiWindowFlags_NoInputs or ImGuiWindowFlags_NoScrollbar are also set.
- - 2017/12/13 (1.53) - renamed GetItemsLineHeightWithSpacing() to GetFrameHeightWithSpacing(). Kept redirection function (will obsolete).
- - 2017/12/13 (1.53) - obsoleted IsRootWindowFocused() in favor of using IsWindowFocused(ImGuiFocusedFlags_RootWindow). Kept redirection function (will obsolete).
- - obsoleted IsRootWindowOrAnyChildFocused() in favor of using IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows). Kept redirection function (will obsolete).
- - 2017/12/12 (1.53) - renamed ImGuiTreeNodeFlags_AllowOverlapMode to ImGuiTreeNodeFlags_AllowItemOverlap. Kept redirection enum (will obsolete).
- - 2017/12/10 (1.53) - removed SetNextWindowContentWidth(), prefer using SetNextWindowContentSize(). Kept redirection function (will obsolete).
- - 2017/11/27 (1.53) - renamed ImGuiTextBuffer::append() helper to appendf(), appendv() to appendfv(). If you copied the 'Log' demo in your code, it uses appendv() so that needs to be renamed.
- - 2017/11/18 (1.53) - Style, Begin: removed ImGuiWindowFlags_ShowBorders window flag. Borders are now fully set up in the ImGuiStyle structure (see e.g. style.FrameBorderSize, style.WindowBorderSize). Use ImGui::ShowStyleEditor() to look them up.
- Please note that the style system will keep evolving (hopefully stabilizing in Q1 2018), and so custom styles will probably subtly break over time. It is recommended you use the StyleColorsClassic(), StyleColorsDark(), StyleColorsLight() functions.
- - 2017/11/18 (1.53) - Style: removed ImGuiCol_ComboBg in favor of combo boxes using ImGuiCol_PopupBg for consistency.
- - 2017/11/18 (1.53) - Style: renamed ImGuiCol_ChildWindowBg to ImGuiCol_ChildBg.
- - 2017/11/18 (1.53) - Style: renamed style.ChildWindowRounding to style.ChildRounding, ImGuiStyleVar_ChildWindowRounding to ImGuiStyleVar_ChildRounding.
- - 2017/11/02 (1.53) - obsoleted IsRootWindowOrAnyChildHovered() in favor of using IsWindowHovered(ImGuiHoveredFlags_RootAndChildWindows);
- - 2017/10/24 (1.52) - renamed IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCS/IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCS to IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCTIONS/IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS for consistency.
- - 2017/10/20 (1.52) - changed IsWindowHovered() default parameters behavior to return false if an item is active in another window (e.g. click-dragging item from another window to this window). You can use the newly introduced IsWindowHovered() flags to requests this specific behavior if you need it.
- - 2017/10/20 (1.52) - marked IsItemHoveredRect()/IsMouseHoveringWindow() as obsolete, in favor of using the newly introduced flags for IsItemHovered() and IsWindowHovered(). See https://github.com/ocornut/imgui/issues/1382 for details.
- removed the IsItemRectHovered()/IsWindowRectHovered() names introduced in 1.51 since they were merely more consistent names for the two functions we are now obsoleting.
- IsItemHoveredRect() --> IsItemHovered(ImGuiHoveredFlags_RectOnly)
- IsMouseHoveringAnyWindow() --> IsWindowHovered(ImGuiHoveredFlags_AnyWindow)
- IsMouseHoveringWindow() --> IsWindowHovered(ImGuiHoveredFlags_AllowWhenBlockedByPopup | ImGuiHoveredFlags_AllowWhenBlockedByActiveItem) [weird, old behavior]
- - 2017/10/17 (1.52) - marked the old 5-parameters version of Begin() as obsolete (still available). Use SetNextWindowSize()+Begin() instead!
- - 2017/10/11 (1.52) - renamed AlignFirstTextHeightToWidgets() to AlignTextToFramePadding(). Kept inline redirection function (will obsolete).
- - 2017/09/26 (1.52) - renamed ImFont::Glyph to ImFontGlyph. Kept redirection typedef (will obsolete).
- - 2017/09/25 (1.52) - removed SetNextWindowPosCenter() because SetNextWindowPos() now has the optional pivot information to do the same and more. Kept redirection function (will obsolete).
- - 2017/08/25 (1.52) - io.MousePos needs to be set to ImVec2(-FLT_MAX,-FLT_MAX) when mouse is unavailable/missing. Previously ImVec2(-1,-1) was enough but we now accept negative mouse coordinates. In your backend if you need to support unavailable mouse, make sure to replace "io.MousePos = ImVec2(-1,-1)" with "io.MousePos = ImVec2(-FLT_MAX,-FLT_MAX)".
- - 2017/08/22 (1.51) - renamed IsItemHoveredRect() to IsItemRectHovered(). Kept inline redirection function (will obsolete). -> (1.52) use IsItemHovered(ImGuiHoveredFlags_RectOnly)!
- - renamed IsMouseHoveringAnyWindow() to IsAnyWindowHovered() for consistency. Kept inline redirection function (will obsolete).
- - renamed IsMouseHoveringWindow() to IsWindowRectHovered() for consistency. Kept inline redirection function (will obsolete).
- - 2017/08/20 (1.51) - renamed GetStyleColName() to GetStyleColorName() for consistency.
- - 2017/08/20 (1.51) - added PushStyleColor(ImGuiCol idx, ImU32 col) overload, which _might_ cause an "ambiguous call" compilation error if you are using ImColor() with implicit cast. Cast to ImU32 or ImVec4 explicily to fix.
- - 2017/08/15 (1.51) - marked the weird IMGUI_ONCE_UPON_A_FRAME helper macro as obsolete. prefer using the more explicit ImGuiOnceUponAFrame type.
- - 2017/08/15 (1.51) - changed parameter order for BeginPopupContextWindow() from (const char*,int buttons,bool also_over_items) to (const char*,int buttons,bool also_over_items). Note that most calls relied on default parameters completely.
- - 2017/08/13 (1.51) - renamed ImGuiCol_Column to ImGuiCol_Separator, ImGuiCol_ColumnHovered to ImGuiCol_SeparatorHovered, ImGuiCol_ColumnActive to ImGuiCol_SeparatorActive. Kept redirection enums (will obsolete).
- - 2017/08/11 (1.51) - renamed ImGuiSetCond_Always to ImGuiCond_Always, ImGuiSetCond_Once to ImGuiCond_Once, ImGuiSetCond_FirstUseEver to ImGuiCond_FirstUseEver, ImGuiSetCond_Appearing to ImGuiCond_Appearing. Kept redirection enums (will obsolete).
- - 2017/08/09 (1.51) - removed ValueColor() helpers, they are equivalent to calling Text(label) + SameLine() + ColorButton().
- - 2017/08/08 (1.51) - removed ColorEditMode() and ImGuiColorEditMode in favor of ImGuiColorEditFlags and parameters to the various Color*() functions. The SetColorEditOptions() allows to initialize default but the user can still change them with right-click context menu.
- - changed prototype of 'ColorEdit4(const char* label, float col[4], bool show_alpha = true)' to 'ColorEdit4(const char* label, float col[4], ImGuiColorEditFlags flags = 0)', where passing flags = 0x01 is a safe no-op (hello dodgy backward compatibility!). - check and run the demo window, under "Color/Picker Widgets", to understand the various new options.
- - changed prototype of rarely used 'ColorButton(ImVec4 col, bool small_height = false, bool outline_border = true)' to 'ColorButton(const char* desc_id, ImVec4 col, ImGuiColorEditFlags flags = 0, ImVec2 size = ImVec2(0, 0))'
- - 2017/07/20 (1.51) - removed IsPosHoveringAnyWindow(ImVec2), which was partly broken and misleading. ASSERT + redirect user to io.WantCaptureMouse
- - 2017/05/26 (1.50) - removed ImFontConfig::MergeGlyphCenterV in favor of a more multipurpose ImFontConfig::GlyphOffset.
- - 2017/05/01 (1.50) - renamed ImDrawList::PathFill() (rarely used directly) to ImDrawList::PathFillConvex() for clarity.
- - 2016/11/06 (1.50) - BeginChild(const char*) now applies the stack id to the provided label, consistently with other functions as it should always have been. It shouldn't affect you unless (extremely unlikely) you were appending multiple times to a same child from different locations of the stack id. If that's the case, generate an id with GetId() and use it instead of passing string to BeginChild().
- - 2016/10/15 (1.50) - avoid 'void* user_data' parameter to io.SetClipboardTextFn/io.GetClipboardTextFn pointers. We pass io.ClipboardUserData to it.
- - 2016/09/25 (1.50) - style.WindowTitleAlign is now a ImVec2 (ImGuiAlign enum was removed). set to (0.5f,0.5f) for horizontal+vertical centering, (0.0f,0.0f) for upper-left, etc.
- - 2016/07/30 (1.50) - SameLine(x) with x>0.0f is now relative to left of column/group if any, and not always to left of window. This was sort of always the intent and hopefully breakage should be minimal.
- - 2016/05/12 (1.49) - title bar (using ImGuiCol_TitleBg/ImGuiCol_TitleBgActive colors) isn't rendered over a window background (ImGuiCol_WindowBg color) anymore.
- If your TitleBg/TitleBgActive alpha was 1.0f or you are using the default theme it will not affect you, otherwise if <1.0f you need tweak your custom theme to readjust for the fact that we don't draw a WindowBg background behind the title bar.
- This helper function will convert an old TitleBg/TitleBgActive color into a new one with the same visual output, given the OLD color and the OLD WindowBg color:
- ImVec4 ConvertTitleBgCol(const ImVec4& win_bg_col, const ImVec4& title_bg_col) { float new_a = 1.0f - ((1.0f - win_bg_col.w) * (1.0f - title_bg_col.w)), k = title_bg_col.w / new_a; return ImVec4((win_bg_col.x * win_bg_col.w + title_bg_col.x) * k, (win_bg_col.y * win_bg_col.w + title_bg_col.y) * k, (win_bg_col.z * win_bg_col.w + title_bg_col.z) * k, new_a); }
- If this is confusing, pick the RGB value from title bar from an old screenshot and apply this as TitleBg/TitleBgActive. Or you may just create TitleBgActive from a tweaked TitleBg color.
- - 2016/05/07 (1.49) - removed confusing set of GetInternalState(), GetInternalStateSize(), SetInternalState() functions. Now using CreateContext(), DestroyContext(), GetCurrentContext(), SetCurrentContext().
- - 2016/05/02 (1.49) - renamed SetNextTreeNodeOpened() to SetNextTreeNodeOpen(), no redirection.
- - 2016/05/01 (1.49) - obsoleted old signature of CollapsingHeader(const char* label, const char* str_id = NULL, bool display_frame = true, bool default_open = false) as extra parameters were badly designed and rarely used. You can replace the "default_open = true" flag in new API with CollapsingHeader(label, ImGuiTreeNodeFlags_DefaultOpen).
- - 2016/04/26 (1.49) - changed ImDrawList::PushClipRect(ImVec4 rect) to ImDrawList::PushClipRect(Imvec2 min,ImVec2 max,bool intersect_with_current_clip_rect=false). Note that higher-level ImGui::PushClipRect() is preferable because it will clip at logic/widget level, whereas ImDrawList::PushClipRect() only affect your renderer.
- - 2016/04/03 (1.48) - removed style.WindowFillAlphaDefault setting which was redundant. Bake default BG alpha inside style.Colors[ImGuiCol_WindowBg] and all other Bg color values. (ref github issue #337).
- - 2016/04/03 (1.48) - renamed ImGuiCol_TooltipBg to ImGuiCol_PopupBg, used by popups/menus and tooltips. popups/menus were previously using ImGuiCol_WindowBg. (ref github issue #337)
- - 2016/03/21 (1.48) - renamed GetWindowFont() to GetFont(), GetWindowFontSize() to GetFontSize(). Kept inline redirection function (will obsolete).
- - 2016/03/02 (1.48) - InputText() completion/history/always callbacks: if you modify the text buffer manually (without using DeleteChars()/InsertChars() helper) you need to maintain the BufTextLen field. added an assert.
- - 2016/01/23 (1.48) - fixed not honoring exact width passed to PushItemWidth(), previously it would add extra FramePadding.x*2 over that width. if you had manual pixel-perfect alignment in place it might affect you.
- - 2015/12/27 (1.48) - fixed ImDrawList::AddRect() which used to render a rectangle 1 px too large on each axis.
- - 2015/12/04 (1.47) - renamed Color() helpers to ValueColor() - dangerously named, rarely used and probably to be made obsolete.
- - 2015/08/29 (1.45) - with the addition of horizontal scrollbar we made various fixes to inconsistencies with dealing with cursor position.
- GetCursorPos()/SetCursorPos() functions now include the scrolled amount. It shouldn't affect the majority of users, but take note that SetCursorPosX(100.0f) puts you at +100 from the starting x position which may include scrolling, not at +100 from the window left side.
- GetContentRegionMax()/GetWindowContentRegionMin()/GetWindowContentRegionMax() functions allow include the scrolled amount. Typically those were used in cases where no scrolling would happen so it may not be a problem, but watch out!
- - 2015/08/29 (1.45) - renamed style.ScrollbarWidth to style.ScrollbarSize
- - 2015/08/05 (1.44) - split imgui.cpp into extra files: imgui_demo.cpp imgui_draw.cpp imgui_internal.h that you need to add to your project.
- - 2015/07/18 (1.44) - fixed angles in ImDrawList::PathArcTo(), PathArcToFast() (introduced in 1.43) being off by an extra PI for no justifiable reason
- - 2015/07/14 (1.43) - add new ImFontAtlas::AddFont() API. For the old AddFont***, moved the 'font_no' parameter of ImFontAtlas::AddFont** functions to the ImFontConfig structure.
- you need to render your textured triangles with bilinear filtering to benefit from sub-pixel positioning of text.
- - 2015/07/08 (1.43) - switched rendering data to use indexed rendering. this is saving a fair amount of CPU/GPU and enables us to get anti-aliasing for a marginal cost.
- this necessary change will break your rendering function! the fix should be very easy. sorry for that :(
- - if you are using a vanilla copy of one of the imgui_impl_XXX.cpp provided in the example, you just need to update your copy and you can ignore the rest.
- - the signature of the io.RenderDrawListsFn handler has changed!
- old: ImGui_XXXX_RenderDrawLists(ImDrawList** const cmd_lists, int cmd_lists_count)
- new: ImGui_XXXX_RenderDrawLists(ImDrawData* draw_data).
- parameters: 'cmd_lists' becomes 'draw_data->CmdLists', 'cmd_lists_count' becomes 'draw_data->CmdListsCount'
- ImDrawList: 'commands' becomes 'CmdBuffer', 'vtx_buffer' becomes 'VtxBuffer', 'IdxBuffer' is new.
- ImDrawCmd: 'vtx_count' becomes 'ElemCount', 'clip_rect' becomes 'ClipRect', 'user_callback' becomes 'UserCallback', 'texture_id' becomes 'TextureId'.
- - each ImDrawList now contains both a vertex buffer and an index buffer. For each command, render ElemCount/3 triangles using indices from the index buffer.
- - if you REALLY cannot render indexed primitives, you can call the draw_data->DeIndexAllBuffers() method to de-index the buffers. This is slow and a waste of CPU/GPU. Prefer using indexed rendering!
- - refer to code in the examples/ folder or ask on the GitHub if you are unsure of how to upgrade. please upgrade!
- - 2015/07/10 (1.43) - changed SameLine() parameters from int to float.
- - 2015/07/02 (1.42) - renamed SetScrollPosHere() to SetScrollFromCursorPos(). Kept inline redirection function (will obsolete).
- - 2015/07/02 (1.42) - renamed GetScrollPosY() to GetScrollY(). Necessary to reduce confusion along with other scrolling functions, because positions (e.g. cursor position) are not equivalent to scrolling amount.
- - 2015/06/14 (1.41) - changed ImageButton() default bg_col parameter from (0,0,0,1) (black) to (0,0,0,0) (transparent) - makes a difference when texture have transparence
- - 2015/06/14 (1.41) - changed Selectable() API from (label, selected, size) to (label, selected, flags, size). Size override should have been rarely be used. Sorry!
- - 2015/05/31 (1.40) - renamed GetWindowCollapsed() to IsWindowCollapsed() for consistency. Kept inline redirection function (will obsolete).
- - 2015/05/31 (1.40) - renamed IsRectClipped() to IsRectVisible() for consistency. Note that return value is opposite! Kept inline redirection function (will obsolete).
- - 2015/05/27 (1.40) - removed the third 'repeat_if_held' parameter from Button() - sorry! it was rarely used and inconsistent. Use PushButtonRepeat(true) / PopButtonRepeat() to enable repeat on desired buttons.
- - 2015/05/11 (1.40) - changed BeginPopup() API, takes a string identifier instead of a bool. ImGui needs to manage the open/closed state of popups. Call OpenPopup() to actually set the "open" state of a popup. BeginPopup() returns true if the popup is opened.
- - 2015/05/03 (1.40) - removed style.AutoFitPadding, using style.WindowPadding makes more sense (the default values were already the same).
- - 2015/04/13 (1.38) - renamed IsClipped() to IsRectClipped(). Kept inline redirection function until 1.50.
- - 2015/04/09 (1.38) - renamed ImDrawList::AddArc() to ImDrawList::AddArcFast() for compatibility with future API
- - 2015/04/03 (1.38) - removed ImGuiCol_CheckHovered, ImGuiCol_CheckActive, replaced with the more general ImGuiCol_FrameBgHovered, ImGuiCol_FrameBgActive.
- - 2014/04/03 (1.38) - removed support for passing -FLT_MAX..+FLT_MAX as the range for a SliderFloat(). Use DragFloat() or Inputfloat() instead.
- - 2015/03/17 (1.36) - renamed GetItemBoxMin()/GetItemBoxMax()/IsMouseHoveringBox() to GetItemRectMin()/GetItemRectMax()/IsMouseHoveringRect(). Kept inline redirection function until 1.50.
- - 2015/03/15 (1.36) - renamed style.TreeNodeSpacing to style.IndentSpacing, ImGuiStyleVar_TreeNodeSpacing to ImGuiStyleVar_IndentSpacing
- - 2015/03/13 (1.36) - renamed GetWindowIsFocused() to IsWindowFocused(). Kept inline redirection function until 1.50.
- - 2015/03/08 (1.35) - renamed style.ScrollBarWidth to style.ScrollbarWidth (casing)
- - 2015/02/27 (1.34) - renamed OpenNextNode(bool) to SetNextTreeNodeOpened(bool, ImGuiSetCond). Kept inline redirection function until 1.50.
- - 2015/02/27 (1.34) - renamed ImGuiSetCondition_*** to ImGuiSetCond_***, and _FirstUseThisSession becomes _Once.
- - 2015/02/11 (1.32) - changed text input callback ImGuiTextEditCallback return type from void-->int. reserved for future use, return 0 for now.
- - 2015/02/10 (1.32) - renamed GetItemWidth() to CalcItemWidth() to clarify its evolving behavior
- - 2015/02/08 (1.31) - renamed GetTextLineSpacing() to GetTextLineHeightWithSpacing()
- - 2015/02/01 (1.31) - removed IO.MemReallocFn (unused)
- - 2015/01/19 (1.30) - renamed ImGuiStorage::GetIntPtr()/GetFloatPtr() to GetIntRef()/GetIntRef() because Ptr was conflicting with actual pointer storage functions.
- - 2015/01/11 (1.30) - big font/image API change! now loads TTF file. allow for multiple fonts. no need for a PNG loader.
- - 2015/01/11 (1.30) - removed GetDefaultFontData(). uses io.Fonts->GetTextureData*() API to retrieve uncompressed pixels.
- - old: const void* png_data; unsigned int png_size; ImGui::GetDefaultFontData(NULL, NULL, &png_data, &png_size); [..Upload texture to GPU..];
- - new: unsigned char* pixels; int width, height; io.Fonts->GetTexDataAsRGBA32(&pixels, &width, &height); [..Upload texture to GPU..]; io.Fonts->SetTexID(YourTexIdentifier);
- you now have more flexibility to load multiple TTF fonts and manage the texture buffer for internal needs. It is now recommended that you sample the font texture with bilinear interpolation.
- - 2015/01/11 (1.30) - added texture identifier in ImDrawCmd passed to your render function (we can now render images). make sure to call io.Fonts->SetTexID()
- - 2015/01/11 (1.30) - removed IO.PixelCenterOffset (unnecessary, can be handled in user projection matrix)
- - 2015/01/11 (1.30) - removed ImGui::IsItemFocused() in favor of ImGui::IsItemActive() which handles all widgets
- - 2014/12/10 (1.18) - removed SetNewWindowDefaultPos() in favor of new generic API SetNextWindowPos(pos, ImGuiSetCondition_FirstUseEver)
- - 2014/11/28 (1.17) - moved IO.Font*** options to inside the IO.Font-> structure (FontYOffset, FontTexUvForWhite, FontBaseScale, FontFallbackGlyph)
- - 2014/11/26 (1.17) - reworked syntax of IMGUI_ONCE_UPON_A_FRAME helper macro to increase compiler compatibility
- - 2014/11/07 (1.15) - renamed IsHovered() to IsItemHovered()
- - 2014/10/02 (1.14) - renamed IMGUI_INCLUDE_IMGUI_USER_CPP to IMGUI_INCLUDE_IMGUI_USER_INL and imgui_user.cpp to imgui_user.inl (more IDE friendly)
- - 2014/09/25 (1.13) - removed 'text_end' parameter from IO.SetClipboardTextFn (the string is now always zero-terminated for simplicity)
- - 2014/09/24 (1.12) - renamed SetFontScale() to SetWindowFontScale()
- - 2014/09/24 (1.12) - moved IM_MALLOC/IM_REALLOC/IM_FREE preprocessor defines to IO.MemAllocFn/IO.MemReallocFn/IO.MemFreeFn
- - 2014/08/30 (1.09) - removed IO.FontHeight (now computed automatically)
- - 2014/08/30 (1.09) - moved IMGUI_FONT_TEX_UV_FOR_WHITE preprocessor define to IO.FontTexUvForWhite
- - 2014/08/28 (1.09) - changed the behavior of IO.PixelCenterOffset following various rendering fixes

- - Individuals: you can support continued development via PayPal donations. See README.
- - If you are experienced with Dear ImGui and C++, look at the github issues, look at the Wiki, read docs/TODO.txt
- and see how you want to help and can help!
- - Disclose your usage of Dear ImGui via a dev blog post, a tweet, a screenshot, a mention somewhere etc.
- You may post screenshot or links in the gallery threads (github.com/ocornut/imgui/issues/3488). Visuals are ideal as they inspire other programmers.
- But even without visuals, disclosing your use of dear imgui help the library grow credibility, and help other teams and programmers with taking decisions.
- - If you have issues or if you need to hack into the library, even if you don't expect any support it is useful that you share your issues (on github or privately).

-// DLL users:
-// - Heaps and globals are not shared across DLL boundaries!
-// - You will need to call SetCurrentContext() + SetAllocatorFunctions() for each static/DLL boundary you are calling from.
-// - Same apply for hot-reloading mechanisms that are reliant on reloading DLL (note that many hot-reloading mechanism works without DLL).
-// - Using Dear ImGui via a shared library is not recommended, because of function call overhead and because we don't guarantee backward nor forward ABI compatibility.
-// - Confused? In a debugger: add GImGui to your watch window and notice how its value changes depending on your current location (which DLL boundary you are in).
-
-// Current context pointer. Implicitly used by all Dear ImGui functions. Always assumed to be != NULL.
-// - ImGui::CreateContext() will automatically set this pointer if it is NULL.
-// Change to a different context by calling ImGui::SetCurrentContext().
-// - Important: Dear ImGui functions are not thread-safe because of this pointer.
-// If you want thread-safety to allow N threads to access N different contexts:
-// - Change this variable to use thread local storage so each thread can refer to a different context, in your imconfig.h:
-// struct ImGuiContext;
-// extern thread_local ImGuiContext* MyImGuiTLS;
-// #define GImGui MyImGuiTLS
-// And then define MyImGuiTLS in one of your cpp file. Note that thread_local is a C++11 keyword, earlier C++ uses compiler-specific keyword.
-// - Future development aim to make this context pointer explicit to all calls. Also read https://github.com/ocornut/imgui/issues/586
-// - If you need a finite number of contexts, you may compile and use multiple instances of the ImGui code from different namespace.
-// - DLL users: read comments above.

- // - You can bypass the hovering restriction by using ImGuiHoveredFlags_AllowWhenBlockedByPopup when calling IsItemHovered() or IsWindowHovered().
- // - IMPORTANT: Popup identifiers are relative to the current ID stack, so OpenPopup and BeginPopup generally needs to be at the same level of the stack.

- // Tables
- // [BETA API] API may evolve slightly! If you use this, please update to the next version when it comes out!
- // - Full-featured replacement for old Columns API.
- // - See Demo->Tables for demo code.
- // - See top of imgui_tables.cpp for general commentary.
- // - See ImGuiTableFlags_ and ImGuiTableColumnFlags_ enums for a description of available flags.
- // The typical call flow is:
- // - 1. Call BeginTable().
- // - 2. Optionally call TableSetupColumn() to submit column name/flags/defaults.
- // - 3. Optionally call TableSetupScrollFreeze() to request scroll freezing of columns/rows.
- // - 4. Optionally call TableHeadersRow() to submit a header row. Names are pulled from TableSetupColumn() data.
- // - 5. Populate contents:
- // - In most situations you can use TableNextRow() + TableSetColumnIndex(N) to start appending into a column.
- // - If you are using tables as a sort of grid, where every columns is holding the same type of contents,
- // you may prefer using TableNextColumn() instead of TableNextRow() + TableSetColumnIndex().
- // TableNextColumn() will automatically wrap-around into the next row if needed.
- // - IMPORTANT: Comparatively to the old Columns() API, we need to call TableNextColumn() for the first column!
- // - Summary of possible call flow:
- // --------------------------------------------------------------------------------------------------------
- // TableNextRow() -> TableSetColumnIndex(0) -> Text("Hello 0") -> TableSetColumnIndex(1) -> Text("Hello 1") // OK
- // TableNextRow() -> TableNextColumn() -> Text("Hello 0") -> TableNextColumn() -> Text("Hello 1") // OK
- // TableNextColumn() -> Text("Hello 0") -> TableNextColumn() -> Text("Hello 1") // OK: TableNextColumn() automatically gets to next row!
- // TableNextRow() -> Text("Hello 0") // Not OK! Missing TableSetColumnIndex() or TableNextColumn()! Text will not appear!

- // - Use TableSetupColumn() to specify label, resizing policy, default width/weight, id, various other flags etc.
- // - Use TableHeadersRow() to create a header row and automatically submit a TableHeader() for each column.
- // Headers are required to perform: reordering, sorting, and opening the context menu.
- // The context menu can also be made available in columns body using ImGuiTableFlags_ContextMenuInBody.
- // - You may manually submit headers using TableNextRow() + TableHeader() calls, but this is only useful in

- // - Call TableGetSortSpecs() to retrieve latest sort specs for the table. NULL when not sorting.
- // - When 'SpecsDirty == true' you should sort your data. It will be true when sorting specs have changed
- // since last call, or the first time. Make sure to set 'SpecsDirty = false' after sorting, else you may

-// Flags for ImGui::BeginTable()
-// [BETA API] API may evolve slightly! If you use this, please update to the next version when it comes out!
-// - Important! Sizing policies have complex and subtle side effects, more so than you would expect.
-// Read comments/demos carefully + experiment with live demos to get acquainted with them.
-// - The DEFAULT sizing policies are:
-// - Default to ImGuiTableFlags_SizingFixedFit if ScrollX is on, or if host window has ImGuiWindowFlags_AlwaysAutoResize.
-// - Default to ImGuiTableFlags_SizingStretchSame if ScrollX is off.
-// - When ScrollX is off:
-// - Table defaults to ImGuiTableFlags_SizingStretchSame -> all Columns defaults to ImGuiTableColumnFlags_WidthStretch with same weight.
-// - Columns sizing policy allowed: Stretch (default), Fixed/Auto.
-// - Fixed Columns will generally obtain their requested width (unless the table cannot fit them all).
-// - Stretch Columns will share the remaining width.
-// - Mixed Fixed/Stretch columns is possible but has various side-effects on resizing behaviors.
-// The typical use of mixing sizing policies is: any number of LEADING Fixed columns, followed by one or two TRAILING Stretch columns.
-// (this is because the visible order of columns have subtle but necessary effects on how they react to manual resizing).
-// - When ScrollX is on:
-// - Table defaults to ImGuiTableFlags_SizingFixedFit -> all Columns defaults to ImGuiTableColumnFlags_WidthFixed
-// - Columns sizing policy allowed: Fixed/Auto mostly.
-// - Fixed Columns can be enlarged as needed. Table will show an horizontal scrollbar if needed.
-// - When using auto-resizing (non-resizable) fixed columns, querying the content width to use item right-alignment e.g. SetNextItemWidth(-FLT_MIN) doesn't make sense, would create a feedback loop.
-// - Using Stretch columns OFTEN DOES NOT MAKE SENSE if ScrollX is on, UNLESS you have specified a value for 'inner_width' in BeginTable().
-// If you specify a value for 'inner_width' then effectively the scrolling space is known and Stretch or mixed Fixed/Stretch columns become meaningful again.
-// - Read on documentation at the top of imgui_tables.cpp for details.

-// dear imgui, v1.82 WIP
-// (demo code)
-
-// Help:
-// - Read FAQ at http://dearimgui.org/faq
-// - Newcomers, read 'Programmer guide' in imgui.cpp for notes on how to setup Dear ImGui in your codebase.
-// - Call and read ImGui::ShowDemoWindow() in imgui_demo.cpp. All applications in examples/ are doing that.
-// Read imgui.cpp for more details, documentation and comments.
-// Get latest version at https://github.com/ocornut/imgui
-
-// Message to the person tempted to delete this file when integrating Dear ImGui into their code base:
-// Do NOT remove this file from your project! Think again! It is the most useful reference code that you and other
-// coders will want to refer to and call. Have the ImGui::ShowDemoWindow() function wired in an always-available
-// debug menu of your game/app! Removing this file from your project is hindering access to documentation for everyone
-// in your team, likely leading you to poorer usage of the library.
-// Everything in this file will be stripped out by the linker if you don't call ImGui::ShowDemoWindow().
-// If you want to link core Dear ImGui in your shipped builds but want a thorough guarantee that the demo will not be
-// linked, you can setup your imconfig.h with #define IMGUI_DISABLE_DEMO_WINDOWS and those functions will be empty.
-// In other situation, whenever you have Dear ImGui available you probably want this to be available for reference.
-// Thank you,
-// -Your beloved friend, imgui_demo.cpp (which you won't delete)
-
-// Message to beginner C/C++ programmers about the meaning of the 'static' keyword:
-// In this demo code, we frequently we use 'static' variables inside functions. A static variable persist across calls,
-// so it is essentially like a global variable but declared inside the scope of the function. We do this as a way to
-// gather code and data in the same place, to make the demo source code faster to read, faster to write, and smaller
-// in size. It also happens to be a convenient way of storing simple UI related information as long as your function
-// doesn't need to be reentrant or used in multiple threads. This might be a pattern you will want to use in your code,
-// but most of the real data you would be editing is likely going to be stored outside your functions.
-
-// The Demo code in this file is designed to be easy to copy-and-paste in into your application!
-// Because of this:
-// - We never omit the ImGui:: prefix when calling functions, even though most code here is in the same namespace.
-// - We try to declare static variables in the local scope, as close as possible to the code using them.
-// - We never use any of the helpers/facilities used internally by Dear ImGui, unless available in the public API.
-// - We never use maths operators on ImVec2/ImVec4. For our other sources files we use them, and they are provided
-// by imgui_internal.h using the IMGUI_DEFINE_MATH_OPERATORS define. For your own sources file they are optional
-// and require you either enable those, either provide your own via IM_VEC2_CLASS_EXTRA in imconfig.h.
-// Because we can't assume anything about your support of maths operators, we cannot use them in imgui_demo.cpp.
-
-// Navigating this file:
-// - In Visual Studio IDE: CTRL+comma ("Edit.NavigateTo") can follow symbols in comments, whereas CTRL+F12 ("Edit.GoToImplementation") cannot.
-// - With Visual Assist installed: ALT+G ("VAssistX.GoToImplementation") can also follow symbols in comments.

-// ImDrawList: Helper function to calculate a circle's segment count given its radius and a "maximum error" value.
-// Estimation of number of circle segment based on error is derived using method described in https://stackoverflow.com/a/2244088/15194693
-// Number of segments (N) is calculated using equation:
-// N = ceil ( pi / acos(1 - error / r) ) where r > 0, error <= r
-// Our equation is significantly simpler that one in the post thanks for choosing segment that is
-// perpendicular to X axis. Follow steps in the article from this starting condition and you will
-// will get this result.
-//
-// Rendering circles with an odd number of segments, while mathematically correct will produce
-// asymmetrical results on the raster grid. Therefore we're rounding N to next even number (7->8, 8->8, 9->10 etc.)
