     \brief The Qt GUI module provides the basic enablers for graphical
     applications written with Qt.
 
-    The Qt GUI module provides classes for windowing system
-    integration, event handling, OpenGL and OpenGL ES integration,
-    Vulkan integration, 2D graphics, imaging, fonts and typography.
-    These classes are used internally by Qt's user interface technologies
-    and can also be used directly, for instance to write applications using
-    low-level OpenGL ES graphics APIs.
+    The \l{Qt GUI} page contains information about how to use the module.
