<p>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.</p>
