applications written with Qt.

\title Qt GUI
The Qt GUI module provides classes for windowing system
integration, event handling, OpenGL and OpenGL ES integration, 2D
graphics, basic imaging, fonts, and text. These classes are used
internally by Qt's user interface technologies but can also be
used directly, for example to write applications using low-level
OpenGL ES graphics APIs.
For application developers writing user interfaces, Qt provides
higher level APIs, like Qt Quick, that are much more suitable
than the enablers found in the Qt GUI module.
