In principle, you can just embed your image widget in an Fl_Scroll and things should work. Best place to see this might be Greg's tips page - try this one for starters, but check the others too for more tips: http://www.seriss.com/people/erco/fltk/#FltkScrollingCanvas However... I have a vague idea that OpenGL windows don't play nice with being embedded into other views like Fl_Scroll so that may not work for you. In which case it is likely to be a bit trickier... I guess you would have to create your own compound widget with one (or two) Fl_Scrollbar widgets acting as the inputs for the x,y co-ords of your view, and the Fl_Gl_Window as the view, then in your OpenGL code setting the scaling and position of your rendered scene based on these inputs - that's a lot more work, but if your OpenGL scene is complex this approach probably gives you more control over how it is drawn anyway, so may be advantageous!
