I believe that this is a good way to force the correct window hierarchy in terms of transient property and so on. Once I was trying to fix a problem [1] with modal and menu windows (and it worked partially in my tests) by setting additional window attributes (e.g. menu_window()) so that we could find the correct (or: at least a better fitting) parent window in the window list, but this was never completed... :-( Anyway, calling show() on the first modal window before calling show() for the new window will put the first modal window on top of FLTK's internal window list and make it more likely to be selected as the parent window of the new one. > On OSX, I have found that having multiple modal windows can be a bit fragile, > OSX does not really have the concept of modal windows, and the way we enforce > it used to be a bit flaky at times; though that said it seems a lot better > these days, so your ought to be fine! I can't comment on OSX. Albrecht [1] If you tried to open a modal window while a menu was open, then the menu window would become the (a) Windows: "parent window" or (b) Linux/Unix/X11: get the "transient attribute/relationship" of the modal window. Then, when you closed the menu window, the modal window would be closed too. This is probably still the case, and IIRC there's a STR for this, but I don't know which one right now. _______________________________________________ fltk mailing list fltk@easysw.com http://lists.easysw.com/mailman/listinfo/fltk
