+
+    \brief The QPlatformGLContext 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 QPlatformGLContext wrapper.
+
+    There is no factory function for QPlatformGLContexts, but rather only one accessor function.
+    The only place to retrieve a QPlatformGLContext from is through a QPlatformWindow.
+
+    The context which is current for a specific thread can be collected by the currentContext()
+    function. This is how QPlatformGLContext also makes it possible to use the QtOpenGL module
+    withhout using QGLWidget. When using QGLContext::currentContext(), it will ask
+    QPlatformGLContext for the currentContext. Then a corresponding QGLContext will be returned,
+    which maps to the QPlatformGLContext.

+
+    QPlatformIntegration is the single entry point for windowsystem specific functionality when
+    using the QPA platform. It has factory functions for creating platform specific pixmaps and
+    windows. The class also controls the font subsystem.
+
+    QPlatformIntegration is a singelton class which gets instansiated in the QApplication
+    constructor. The QPlatformIntegration instance do not have ownership of objects it creates in
+    functions where the name starts with create. However, functions which don't have a name
+    starting with create acts as assessors to member variables.
+
+    It is not trivial to create or build a platform plugin outside of the Qt source tree. Therefor
+    the recommended approach for making new platform plugin is to copy an existing plugin inside
+    the QTSRCTREE/src/plugins/platform and develop the plugin inside the source tree.
+
+    The minimal platformintegration is the smallest platform integration it is possible to make,
+    which makes it an ideal starting point for new plugins. For a slightly more advanced plugin,
+    consider reviewing the directfb plugin, or the testlite plugin.
