Do you have any suggestions?
That tends to be platform specific, sad to say, so may or may not work depending on what host platform and so forth... For example, on Windows, event delivery tends to be blocked whilst a window is resizing (at least up until XP - maybe they sorted that in Vista/7 ? I don't know, though I doubt it) so you can't reliably process any events then. Not actually sure what OSX does... It may be the same, actually. Yup, just did a crude test, looks like events are stalled during a resize... On other hosts, it may very well depend on what actual window manager is running. Hmm, OK, you may need to give us a bit more detail then! -- Ian _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
