Using OpenGL in a regular window (Win32)

Question

I want to use OpenGL in my WndProc but I'm not sure how. I also don't want GL to occupy the whole screen, just a portion of the screen. In the end I basically want to make a drawing win32 app but use OGL instead of GDI. so how can I tell GL to use my control (a panel) 's hdc for drawing?

Thanks

Answer 1

When you call wglCreateContext, pass the control's HDC instead of the window. The same thing works on OpenGL and DirectX.

Answer 2

You can use wglCreateContext on any HDC, but you can't mix the drawing with GDI.
