+ \class QPlatformOpenGLContext
+ \since 4.8
+ \internal
+ \preliminary
+ \ingroup qpa
+
+ \brief The QPlatformOpenGLContext class provides an abstraction for native GL contexts.
+
+ In QPA the way to support OpenGL or OpenVG or other technologies that requires a native GL
+ context is through the QPlatformOpenGLContext wrapper.
+
+ There is no factory function for QPlatformOpenGLContexts, but rather only one accessor function.
+ The only place to retrieve a QPlatformOpenGLContext from is through a QPlatformWindow.
+
+ The context which is current for a specific thread can be collected by the currentContext()
+ function. This is how QPlatformOpenGLContext also makes it possible to use the QtGui module
+ withhout using QOpenGLWidget. When using QOpenGLContext::currentContext(), it will ask
+ QPlatformOpenGLContext for the currentContext. Then a corresponding QOpenGLContext will be returned,
+ which maps to the QPlatformOpenGLContext.
+*/
+
+/*! \fn void QPlatformOpenGLContext::swapBuffers(QPlatformSurface *surface)
+ Reimplement in subclass to native swap buffers calls
+
+ The implementation must support being called in a thread different than the gui-thread.
+*/
+
+/*! \fn QFunctionPointer QPlatformOpenGLContext::getProcAddress(const QByteArray &procName)
+ Reimplement in subclass to native getProcAddr calls.
