This is to cast my vote on this RFC. Yes, functions Fl_Widget::is_group() and is_window() would be extremely useful, for instance they're badly needed for the proposed Fl_Printer class. I favor Fl_Group *Fl_Widget::is_group(), and similarly for Fl_Window, as return type because the widget in question will in most cases have to be cast to Fl_Group.
For FLTK-1.3-cocoa, I had to makedo with the absence of what could be an is_glwindow() function. So I would suggest to add this one as well. More generally, could there be an Fl_Widget::is_Fl_<i>type</i>() function fo each FLTK widget type ? They should account for inheritances with is_group() true for an Fl_Window* and an Fl_Gl_Window*. _______________________________________________ fltk-dev mailing list fltk-dev@easysw.com http://lists.easysw.com/mailman/listinfo/fltk-dev
