Well, if as Cyrille suggests we pass the modifiers to element_move_handle(), it can decide whether to use the aspect_ratio or not. It can then be unset once the resizing stops (which is a separate move kind). In fact, then element_move_handle() can handle the setting of the aspect_ratio itself, and the objects won't have to change at all. Much fewer changes. -Lars -- Lars Clausen (http://shasta.cs.uiuc.edu/~lrclause)| Hårdgrim of Numenor "I do not agree with a word that you say, but I |---------------------------- will defend to the death your right to say it." | Where are we going, and --Evelyn Beatrice Hall paraphrasing Voltaire | what's with the handbasket? _______________________________________________ Dia-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/dia-list
