.SH DESCRIPTION
The QGL class is a namespace for miscellaneous identifiers in the Qt OpenGL module.
.PP
Normally you can ignore this class. QGLWidget and the other OpenGL<sup>*</sup> module classes inherit it, so when you make your own QGLWidget subclass you can use the identifiers in the QGL namespace without qualification.
.PP
However, you may occasionally find yourself in situations where you need to refer to these identifiers from outside the QGL namespace's scope, e.g. in static functions. In such cases, simply write e.g. QGL::DoubleBuffer instead of just DoubleBuffer.
.PP
<sup>*</sup> OpenGL is a trademark of Silicon Graphics, Inc. in the United States and other countries.
