Hello, everyone!
The problem is

in a QGLWidget I draw a transporant figure applied with a texture. I see my picture on the screen in the way a desire but when I save the picture into a png file by calling renderPixmap I do not observe there any texture on the surface of the figure, just the plane surface with the color I set for the figure and the figure does not lost its transparence.

Suppose I need to set one of QGLFormat properties but I don't have any idea wich of properties to set up after having read QGLFormat description.

I use QT3.3.5 on Windows XP platform and C++ compiler from Visual Studio Net 2003.
