Thanks for the confirmation. I will update my code to use add_idle(). Right now I'm in the process of finshing two simply examples. (1) Loading an image into a Fl_Box by using DND from a file browser. When the user "drops" the file only the widget, a prompt will appear asking for confirmation. (2) Moving widgets around in a Fl_Double_Window and dropping them into and removing them from Fl_Groups. I coding is pretty much done, but right now I'm trying to simplify them as much as possible. The 2nd example doesn't really use DND, so I may omit that one. -- Alvin _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
