<hr><a name="details"></a><h2>Detailed Description</h2>
The QGL class is a namespace for miscellaneous identifiers
in the Qt OpenGL module.
<p>
<p> Normally you can ignore this class. <a href="qglwidget.html">QGLWidget</a> 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.
<p> 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. <a href="#FormatOption-enum">QGL::DoubleBuffer</a> instead of just <a href="#FormatOption-enum">DoubleBuffer</a>.
<p> <sup>*</sup> OpenGL is a trademark of Silicon Graphics, Inc. in the
United States and other countries.
<p> <p>See also <a href="graphics.html">Graphics Classes</a> and <a href="images.html">Image Processing Classes</a>.
