No, I don't think this is correct - I don't think there is a problem with X per se, rather I think your example is (still) slightly wrong. As I said in earlier posts, you can really only be sure the graphical context is correct for you to call fl_read_image() when you are in the draw() method of the widget you are trying to sample. But you persist in calling it from your callback, so you *can not* expect it to work correctly. The only hope you have of making this work correctly, if you must call fl_read_image() from your callback, is to do a widget- >make_current() immediately before the fl_read_image(). Then it will *probably* work OK for you. As it stands, since your code is flawed, I don't think we can assume anything else about any bugs or misfeatures you are seeing. If you fix your code, and it *still* does not work, *then* maybe there is a problem... _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
