Detailed Description

OpenGL widget.

Derives from Gtk::DrawingArea. The GL capabilities are added using the gdkgl extension library. When using GL commands, always use them between calls to GLWidgetBegin and GLWidgetEnd. Use swapBuffers to swap buffers.

When deriving from GLWidget, implement glDraw() to contain any drawing routines (such as drawing opengl scenes).
