## Detailed Description

The TQGL class is a namespace for miscellaneous identifiers in the TQt OpenGL module.

Normally you can ignore this class. TQGLWidget and the other OpenGL* module classes inherit it, so when you make your own TQGLWidget subclass you can use the identifiers in the TQGL namespace without qualification.

However, you may occasionally find yourself in situations where you need to refer to these identifiers from outside the TQGL namespace's scope, e.g. in static functions. In such cases, simply write e.g. TQGL::DoubleBuffer instead of just DoubleBuffer.
