Classes
class	QOpenGLSharedResource
	The QOpenGLSharedResource class is used to keep track of resources that are shared between OpenGL contexts (like textures, framebuffer objects, shader programs, etc), and clean them up in a safe way when they're no longer needed. \inmodule QtGui. More...
class	QOpenGLSharedResourceGuard
	The QOpenGLSharedResourceGuard class is a convenience sub-class of QOpenGLSharedResource to be used to track a single OpenGL object with a GLuint identifier. The constructor takes a function pointer to a function that will be used to free the resource if and when necessary. \inmodule QtGui. More...
class	QOpenGLContextGroupPrivate
class	QOpenGLMultiGroupSharedResource
	The QOpenGLMultiGroupSharedResource keeps track of a shared resource that might be needed from multiple contexts, like a glyph cache or gradient cache. One instance of the object is created for each group when necessary. The shared resource instance should have a constructor that takes a QOpenGLContext *. To get an instance for a given context one calls T *QOpenGLMultiGroupSharedResourcevalue<T>(context), where T is a sub-class of QOpenGLSharedResource. \inmodule QtGui. More...
class	QOpenGLContextVersionFunctionHelper
class	QOpenGLContextPrivate
