<hr><h2><a name="details"></a>Detailed Description</h2>
The QGL class is a namespace for miscellaneous identifiers in the Qt OpenGL module.
<p>
Normally, you can ignore this class. <a href="qglwidget.html">QGLWidget</a> and the other OpenGL
module classes inherit it, so when you make your own QGLWidget
subclass, you can use the identifiers in the QGL namespace without
qualification.
<p>However, occasionally you may find yourself in situations where you
need ot refer to these identifiers from outside the QGL namespace
scope, e.g. in static utility functions. In such cases, simply write
e.g. <code>QGL::DoubleBuffer</code> instead just <code>DoubleBuffer.</code>
