+    \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.
