[Qt-interest] OpenGL with Qt _ Need_Help

[Alexandre Beraud]

Dear Sujan,

The QGLWidget class is a widget for rendering OpenGL graphics.

QGLWidget provides functionality for displaying OpenGL graphics 
integrated into a Qt application. It is very simple to use. You inherit 
from it and use the subclass like any other QWidget, except that you 
have the choice between using QPainter and standard OpenGL rendering 
commands.

QGLWidget provides three convenient virtual functions that you can 
reimplement in your subclass to perform the typical OpenGL tasks:

paintGL() - Renders the OpenGL scene. Gets called whenever the widget 
needs to be updated.
resizeGL() - Sets up the OpenGL viewport, projection, etc. Gets called 
whenever the widget has been resized (and also when it is shown for the 
first time because all newly created widgets get a resize event 
automatically).
initializeGL() - Sets up the OpenGL rendering context, defines display 
lists, etc. Gets called once before the first time resizeGL() or 
paintGL() is called.
Here is a rough outline of how a QGLWidget subclass might look:
...

Wait... That's what you could read if you just took a look at the 
following documentation, available immediately on the Qt Reference 
Documentation Page (the one you should bookmark one day):
http://doc.trolltech.com/4.5/qtopengl.html

I hope it helps.

Regards,

Alex
