http://wxlua.sourceforge.net/docs/wxluaref.html#wxGLCanvas The wxGLCanvas constructor takes a wxSize as an input. You probably have to specify it, though if it is the first and only child of the wxFrame it should take the client size of the frame and you should use wxDefaultSize. However, sometimes you need to call wxFrame::SendSizeEvent() before wxFrame::Show() to have it correctly lay itself out. Either that or slightly resize the frame by hand while printing wxGLCanvas::GetSize() in your wxEVT_PAINT handler to test what the size is.
