openGL without QGLWidget
Message 1 in thread
Hello,
I am trying to use openGL with a QDialog on Windows 2000 with Qt Professional 3.0.2. It compiles but I do not have any output. Did anyone tried to use openGL without using QGLWidget ?
Any help would be appreciated.

Hello,
I mend by output that I do not see any graphic on the widget. I put a message
box in my drawing function and then I saw the graphic. Without it, I do not see
anything.
Anyone have an idea?

Hello,
That is right. I forgot to add the function SwapBuffers(hdc). Now, It works
well.
Thank you

Hello,
I have a window class derived from QDialog and I use the WGL API to create and make current the openGL context. It compiles but when I run it, I do not see anything.
Did someone was able to use openGL without QGLWidget?
Thank you
