No, this isn't going to work - starting the offscreen then setting the window current is just going to switch the rendering context back to the window... If you want to use the offscreen like this, you'll need to derive a subclass for your outer window, then in its draw() method override the rendering context to the offscreen.... It's a bit more work, but robust, and there have been worked examples of this posted in the lists recently you could refer to. But for what you are describing, the offscreen is probably overkill... simply calling win->make_current() immediately before you call fl_read_image(...) should be enough to get it working. Does it not work? -- Ian _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
