Examples, Platform: Removed the call to ImGui::NewFrame() from the platform _NewFrame() function e.g. ImGui_ImplWin32_NewFrame(), ImGui_ImplSDL2_NewFrame(), ImGui_ImplGlfw_NewFrame(), etc. Moved to main.cpp for consistency. (#1542) 		ago%!(EXTRA string=7 years)
..
README.md Examples: Added .. folder in include path to remove the awkward #include "../imgui_impl_xxx.h" statements. ago%!(EXTRA string=7 years)
imconfig_allegro5.h Examples: Allegro 5: Added support for 32-bit indices setup via defining ImDrawIdx, to avoid an unecessary conversion (Allegro 5 doesn't support 16-bit indices). ago%!(EXTRA string=7 years)

Configuration

Dear ImGui outputs 16-bit vertex indices by default. Allegro doesn't support them natively, so we have two solutions: convert the indices manually in imgui_impl_allegro5.cpp, or compile imgui with 32-bit indices. You can either modify imconfig.h that comes with Dear ImGui (easier), or set a C++ preprocessor option IMGUI_USER_CONFIG to find to a filename. We are providing imconfig_allegro5.h that enables 32-bit indices. Note that the back-end supports BOTH 16-bit and 32-bit indices, but 32-bit indices will be slightly faster as they won't require a manual conversion.

How to Build

  • On Ubuntu 14.04+
g++ -DIMGUI_USER_CONFIG=\"examples/allegro5_example/imconfig_allegro5.h\" -I .. -I ../.. main.cpp imgui_impl_allegro5.cpp ../../imgui*.cpp -lallegro -lallegro_primitives -o allegro5_example
  • On Windows with Visual Studio's CLI
set ALLEGRODIR=path_to_your_allegro5_folder
cl /Zi /MD /I %ALLEGRODIR%\include /DIMGUI_USER_CONFIG=\"examples/allegro5_example/imconfig_allegro5.h\" /I .. /I ..\.. main.cpp imgui_impl_allegro5.cpp ..\..\imgui*.cpp /link /LIBPATH:%ALLEGRODIR%\lib allegro-5.0.10-monolith-md.lib user32.lib
