+    \title Qt OpenGL
+    \brief The QtOpenGL module offers classes that make it easy to
+    use OpenGL in Qt applications.
+
+    \warning Apart from the \l{QGLWidget} class, this module should not be used
+    anymore for new code. Please use the corresponding OpenGL classes in
+    \l{Qt Gui}.
+
+    OpenGL is a standard API for rendering 3D graphics. OpenGL only
+    deals with 3D rendering and provides little or no support for GUI
+    programming issues. The user interface for an OpenGL application
+    must be created with another toolkit, such as Cocoa on the Mac OS X
+    platform, Microsoft Foundation Classes (MFC) under Windows, or Qt
+    on both platforms.
+
+    \note OpenGL is a trademark of Silicon Graphics, Inc. in
+    the United States and other countries.
+
+    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.
+
+    To include the definitions of the module's classes, use the
+    following directive:
+
+    \snippet code/doc_src_qtopengl.cpp 0
+
+    To link against the module, add this line to your \l qmake \c
+    .pro file:
+
+    \snippet code/doc_src_qtopengl.pro 1
+
+    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 using the Qt
+    OpenGL module can take advantage of the whole Qt API for
+    non-OpenGL-specific GUI functionality.
+
+    The \l{Qt OpenGL C++ classes} page gives an overview over the available classes
+    int this module.
