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 Motif on the X platform, Microsoft Foundation Classes (MFC) under Windows, or Qt on both platforms.
注意： OpenGL 是 Silicon (硅谷) 图形公司在美国及其它国家的商标。
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.
要包括模块类定义，使用以下指令：
#include <QtOpenGL>
要链接到模块，添加此行到
qmake
.pro
文件：
QT += opengl
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 QtOpenGL module is available on Windows, X11 and Mac OS X. Qt for Embedded Linux and OpenGL supports OpenGL ES ( OpenGL for Embedded Systems).
注意： To be able to use the OpenGL API in Qt for Embedded Linux , it must be integrated with the Q Window System (QWS). See the Qt for Embedded Linux and OpenGL 文档编制了解细节。
