Examples: DirectX12: Moved the ID3D12GraphicsCommandList* parameter from ImGui_ImplDX12_NewFrame() to ImGui_ImplDX12_RenderDrawData() which makes a lots more sense. (#301)

@ -83,6 +83,7 @@ Other Changes:
|
|||
- Examples: Added SDL+Vulkan example.
|
||||
- Examples: Allegro5: Added support for ImGuiConfigFlags_NoMouseCursorChange flag. Added clipboard support.
|
||||
- Examples: Allegro5: Unindexing buffers ourselves as Allegro indexed drawing primitives are buggy in the DirectX9 back-end.
|
||||
- Examples: DirectX12: Moved the ID3D12GraphicsCommandList* parameter from ImGui_ImplDX12_NewFrame() to ImGui_ImplDX12_RenderDrawData() which makes a lots more sense. (#301)
|
||||
- Examples: FreeGLUT: Added FreeGLUT bindings. Added FreeGLUT+OpenGL2 example. (#801)
|
||||
- Examples: The functions in imgui_impl_xxx.cpp are prefixed with IMGUI_IMPL_API (which defaults to IMGUI_API) to facilitate some uses. (#1888)
|
||||
- Examples: Fixed bindings to use ImGuiMouseCursor_COUNT instead of old name ImGuiMouseCursor_Count_ so they can compile with IMGUI_DISABLE_OBSOLETE_FUNCTIONS. (#1887)
