Hi, I''m currently using Fox 1.0.29. I understand that multiple top windows don''t work in this version of Fox, so I''m playing with MDI for now, instead. I would have expected that using an MDI child window would be very much like using a top level window. In fact, the placement options, initializer, etc. are all different. For example, when I use just a single main window (see the attached example mainwin.rb), the main window will size itself more-or-less perfectly to the size of the contained objects. If I use an mdi client window, however, I apparently must specify the size myself. As far as I can tell, there is no option to size this window based on requests from the widgets that are placed in there at the time the window is created (see attached example mdi.rb). I''m supposing this is really a Fox issue (not an FxRuby issue), so please forgive me if this is the wrong place to post (I''d prefer to start here, since I''m using FxRuby, and Ruby people are just always friendlier :-). My gut feeling is that I should give up on MDI and proceed to 1.2 and multiple top-levels. What do you guys say?
