Do I have to use the OpenGL functions via the QOpenGLFunctions class in order to use "Dynamically Loading Graphics Drivers"? Is QOpenGLFunctions_4_3_Compatibility OK?
According to Dynamically Loading Graphics Drivers from Qt, "When a given environment fails to provide a proper OpenGL 2.0 implementation, it will fall back automatically to ANGLE", AND "The dynamic loading has a significant impact on applications that contain native OpenGL calls: they may fail to link since qmake no longer automatically adds opengl32.lib or libGLESv2.lib. Instead, applications are expected to use the OpenGL functions via the QOpenGLFunctions class". I realized that this means I have to use the OpenGL functions via the QOpenGLFunctions class in order to use "Dynamically Loading Graphics Drivers". But, I want to know "is QOpenGLFunctions_4_3_Compatibility OK?"
Edit1: New functionality in the core OpenGL 4.1 specification includes: Full compatibility with OpenGL ES 2.0 APIs for easier porting between mobile and desktop platforms; The above is from the opengl official website: https://www.khronos.org/news/press/opengl-4-1-released
So, QOpenGLFunctions_4_3_Compatibility must be full compatibility with OpenGL ES 2.0 APIs. Is my understanding correct?
