The user interface for an +OpenGL<sup>*</sup> application must be created with another toolkit, +such as <a href="motif-extension.html#Motif">Motif</a> on the X platform, Microsoft Foundation Classes (MFC) +under Windows, or Qt on <em>both</em> platforms. +<p> 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. +<p> The Qt OpenGL module is implemented as a platform-independent Qt/C++ +wrapper around the platform-dependent GLX, WGL, or AGL C APIs. The +functionality provided is very similar to Mark Kilgard's GLUT library, +but with much more non-OpenGL-specific GUI functionality, i.e. the +whole Qt API. +<p> <h2> Installation +</h2> +<a name="2"></a><p> When you install Qt for X11, the configure script will autodetect if +OpenGL headers and libraries are installed on your system, and if so, +it will include the Qt OpenGL module in the Qt library. (If your +OpenGL headers or libraries are placed in a non-standard directory, +you may need to change the QMAKE_INCDIR_OPENGL and/or +QMAKE_LIBDIR_OPENGL in the config file for your system). Some +configurations require threading to be enabled for OpenGL, so if +OpenGL is not detected, try <tt>configure -thread</tt>. +<p> When you install Qt for Windows, the Qt OpenGL module is always +included. +<p> The Qt OpenGL module is not licensed for use with the Qt Professional +Edition. Consider upgrading to the Qt Enterprise Edition if you +require OpenGL support. +<p> Note about using Mesa on X11: Mesa versions earlier than 3.1 would use +the name "MesaGL" and "MesaGLU" for the libraries, instead of "GL" and +"GLU". If you want to use a pre-3.1 version of Mesa, you must change +the Makefiles to use these library names instead. The easiest way to +do this is to edit the QMAKE_LIBS_OPENGL line in the config file you +are using, changing "-lGL -lGLU" to "-lMesaGL -lMesaGLU"; then run +"configure" again. +<p> <h2> The <a href="qgl.html">QGL</a> Classes +</h2> +<a name="3"></a><p> The OpenGL support classes in Qt are: +<ul> +<li> <a href="qglwidget.html">QGLWidget</a>: An easy-to-use Qt +widget for rendering OpenGL scenes. +<li> <a href="qglcontext.html">QGLContext</a>: Encapsulates an OpenGL rendering context. +<li> <a href="qglformat.html">QGLFormat</a>: Specifies the +display format of a rendering context. +<li> <a href="qglcolormap.html">QGLColormap</a>: Handles indexed +colormaps in GL-index mode. +</ul> +<p> Many applications only need the high-level <a href="qglwidget.html">QGLWidget</a> class. The other +QGL classes provide advanced features. X11 users might like to read +the notes on <a href="opengl-x11-overlays.html">overlays</a>. +<p> See also the <a href="opengl-examples.html">OpenGL examples</a>. +<p> The QGL documentation assumes that you are familiar with OpenGL +programming.
