Hi Markus, the code works great. The frame update through OSG methods is much faster than using FOX's FXGLCanvas::makeCurrent(), no idea why. I also tried to use one common FXGLVisual for all GraphicsWindowFOX's, like in FOX's glviewer example. Works fine, initialization is much faster of course.
Many thanks! Tomas Markus Hein napsal(a): > Hi Tomas, > > today I could check how I implemented the frame-update for multiple Windows > under Win32.
