// dear imgui: Platform Backend for GLUT/FreeGLUT
|
|
// This needs to be used along with a Renderer (e.g. OpenGL2)
|
|
|
|
// !!! GLUT/FreeGLUT IS OBSOLETE PREHISTORIC SOFTWARE. Using GLUT is not recommended unless you really miss the 90's. !!!
|
|
// !!! If someone or something is teaching you GLUT today, you are being abused. Please show some resistance. !!!
|
|
// !!! Nowadays, prefer using GLFW or SDL instead!
|
|
|
|
// Implemented features:
|
|
// [X] Platform: Partial keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy GLUT values will also be supported unless IMGUI_DISABLE_OBSOLETE_KEYIO is set]
|
|
// Issues:
|
|
// [ ] Platform: GLUT is unable to distinguish e.g. Backspace from CTRL+H or TAB from CTRL+I
|
|
// [ ] Platform: Missing horizontal mouse wheel support.
|
|
// [ ] Platform: Missing mouse cursor shape/visibility support.
|
|
// [ ] Platform: Missing clipboard support (not supported by Glut).
|
|
// [ ] Platform: Missing gamepad support.
|
|
|
|
// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
|
|
// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
|
|
// 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
