43	\class QOpenGLFunctions
44	\brief The QOpenGLFunctions class provides cross-platform access to the OpenGL ES 2.0 API.
45	\since 5.0
46	\ingroup painting-3D
47	\inmodule QtGui
48
49	OpenGL ES 2.0 defines a subset of the OpenGL specification that is
50	common across many desktop and embedded OpenGL implementations.
51	However, it can be difficult to use the functions from that subset
52	because they need to be resolved manually on desktop systems.
53
54	QOpenGLFunctions provides a guaranteed API that is available on all
55	OpenGL systems and takes care of function resolution on systems
56	that need it. The recommended way to use QOpenGLFunctions is by
57	direct inheritance:
58
59	\snippet code/src_gui_opengl_qopenglfunctions.cpp 0
60
61	The \c{paintGL()} function can then use any of the OpenGL ES 2.0
62	functions without explicit resolution, such as glActiveTexture()
63	in the following example:
64
65	\snippet code/src_gui_opengl_qopenglfunctions.cpp 1
66
67	QOpenGLFunctions can also be used directly for ad-hoc invocation
68	of OpenGL ES 2.0 functions on all platforms:
69
70	\snippet code/src_gui_opengl_qopenglfunctions.cpp 2
71
72	An alternative approach is to query the context's associated
73	QOpenGLFunctions instance. This is somewhat faster than the previous
74	approach due to avoiding the creation of a new instance, but the difference
75	is fairly small since the internal data structures are shared, and function
76	resolving happens only once for a given context, regardless of the number of
77	QOpenGLFunctions instances initialized for it.
78
79	\snippet code/src_gui_opengl_qopenglfunctions.cpp 3
80
81	QOpenGLFunctions provides wrappers for all OpenGL ES 2.0
82	functions, including the common subset of OpenGL 1.x and ES
83	2.0. While such functions, for example glClear() or
84	glDrawArrays(), can be called also directly, as long as the
85	application links to the platform-specific OpenGL library, calling
86	them via QOpenGLFunctions enables the possibility of dynamically
87	loading the OpenGL implementation.
88
89	The hasOpenGLFeature() and openGLFeatures() functions can be used
90	to determine if the OpenGL implementation has a major OpenGL ES 2.0
91	feature. For example, the following checks if non power of two
92	textures are available:

102	may depend on the implementation.

2179	\class QOpenGLExtraFunctions
2180	\brief The QOpenGLExtraFunctions class provides cross-platform access to the OpenGL ES 3.0, 3.1 and 3.2 API.
2181	\since 5.6
2182	\ingroup painting-3D
2183	\inmodule QtGui
2184
2185	This subclass of QOpenGLFunctions includes the OpenGL ES 3.0, 3.1 and 3.2
2186	functions. These will only work when an OpenGL ES 3.x context, or an
2187	OpenGL context of a version containing the functions in question either in
2188	core or as extension, is in use. This allows developing GLES 3.x
2189	applications in a cross-platform manner: development can happen on a desktop
2190	platform with OpenGL 3.x or 4.x, deploying to a true GLES 3.x device later
2191	on will require no or minimal changes to the application.
2192
2193	\note This class is different from the versioned OpenGL wrappers, for
2194	instance QOpenGLFunctions_3_2_Core. The versioned function wrappers target a
2195	given version and profile of OpenGL. They are therefore not suitable for
2196	cross-OpenGL-OpenGLES development.
