Yes, that is correct. FLTK uses a single threaded approach and executes callback in an order that in this specific case may not be exactly the same as the actual event occurred (by a few microseconds). FLTK *does* support multithreading through locks and awake signals, but there is always only one single GUI thread (which additionally must be the main thread of the application - a requirement by one of the underlaying platforms). - Matthias _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
