\title Qt OpenGL
\brief The Qt OpenGL module offers classes that make it easy to
use OpenGL in Qt applications.
\section1 Introduction
The Qt OpenGL module makes it easy to use OpenGL in Qt applications.
It provides an OpenGL widget class that can be used just like any
other Qt widget, except that it opens an OpenGL display buffer where
you can use the OpenGL API to render the contents.
The Qt OpenGL module is implemented as a platform-independent Qt/C++
wrapper around the platform-dependent GLX (version 1.3 or later),
WGL, or AGL C APIs. Although the basic functionality provided is very
similar to Mark Kilgard's GLUT library, applications can use the
other \l{All Modules}{Qt modules} to implement the rest of the user
interface.
The \l{Qt OpenGL C++ Classes} page gives an overview over the available classes
in this module.

See also the \l {Build with CMake} overview.

\section1 Module Evolution
\l{Changes to Qt OpenGL} lists important changes in the module API
and functionality that were done for the Qt 6 series of Qt.
\section1 Licenses and Trademarks
The Qt OpenGL module is available under commercial licenses from \l{The Qt Company}.
In addition, it is available under free software licenses:
The \l{GNU Lesser General Public License, version 3}, or
the \l{GNU General Public License, version 2}.
See \l{Qt Licensing} for further details.
