[graphic-forms-devel] opengl
by Hugo Duncan 30 Jul '08

Hi, Firstly, many thanks for creating a functional win32 gui toolkit! I am trying to use opengl with a graphic-forms window. So far this has involved creating a new window style, and adding some initialisation code once the window has been created. So far so good. To actually draw anything, a wglCreateContext call is required to create a context, which must be made current with wglMakeCurrent before gl functions are called. Where would be a good place to store this window specific context, and its destructor function, so that it can be accessed in the paint/resize events, etc? I suppose the graphics-context might be an option, though replacing it with an opengl-context might be better which would entail selecting the correct type of context in the proceess-message methods. Any guidance/thoughts you could give would be gratefully received. Regards, Hugo __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
