This class was introduced in Qt 5.6.
Detailed Description
This subclass of QOpenGLFunctions includes the OpenGL ES 3.0, 3.1 and 3.2 functions. These will only work when an OpenGL ES 3.x context, or an OpenGL context of a version containing the functions in question either in core or as extension, is in use. This allows developing GLES 3.x applications in a cross-platform manner: development can happen on a desktop platform with OpenGL 3.x or 4.x, deploying to a true GLES 3.x device later on will require no or minimal changes to the application.
Note: This class is different from the versioned OpenGL wrappers, for instance QOpenGLFunctions_3_2_Core. The versioned function wrappers target a given version and profile of OpenGL. They are therefore not suitable for cross-OpenGL-OpenGLES development.
