Dear ImGui QNX Screen + OpenGL ES 3 example

This example uses:

• imgui_impl_qnx.cpp as the QNX Screen platform backend
• imgui_impl_opengl3.cpp as the renderer backend
• EGL to create an OpenGL ES 3 context and Screen window surface

imgui_impl_opengl3.cpp supports desktop OpenGL and OpenGL ES. On QNX this example compiles it with IMGUI_IMPL_OPENGL_ES3 and uses #version 300 es. No separate Screen/OpenGL renderer backend is required.

Build

Load the QNX SDP environment, then run:

cd examples/example_qnx_opengl3
make

The QNX recursive make files build for the CPUs enabled in your SDP configuration and install the program as example_qnx_opengl3.

Input

The application polls its screen_context_t event queue and forwards every non-SCREEN_EVENT_NONE event to ImGui_ImplQNX_ProcessEvent(). Escape exits the example.
