[Qt-interest] OpenGL inside QT with accelaration

[Nathan Carter]

Dear Mic,

If you want to do OpenGL in Qt, just use a QGLWidget.  You subclass it  
and put inside it all OpenGL code you write yourself, 95% of which  
should be portable to just about any other OpenGL situation.  (See  
QGLWidget docs for where to put what kind of code.)

Hardware acceleration is not something you need to set up within your  
app; it's something you need to set up on your system.  If your system  
OS/hardware can use OpenGL hardware acceleration, Qt will use it.  Is  
this what you were asking?
