I have a question. I work in visual c++ in a document/view arhitecture (SDI application) and i draw some stuff with some opengl functions (cubes, cylinders) but when i hit the "New" menu from the File menu it doesn't erase or clear my drawing :( I don't know why. Can you help me how to ovewrite eventually this : OnFileNew function, and where should i put it? In the CView class or in CMainFrame?
What should i write in it to erase my background after i draw something and to provide a clear canvas ?
Thank you in advance for your help.
