When you say "dynamic" I'll assume that you want the UI to change based on code flow. I have seen Nate do exactly that. Side note: Please Nate show the world your ClassDesigner tricks. Back to the subject at hand: One of the authors Ed Leafe has some example code for using "twitter" and Dabo. In that code you can see some examples of changing the UI layout depending on dynamic data changes and as a result of code flow ( If statements, etc..). For the life of me I can't find the link - but I'm sure someone on the list will provide one. BTW to best of my knowledge the entire twitter app does not use any hand coded UI - it was all done in ClassDesigner. Are you sure you aren't discussing dForm (or dApp) and not dPanel? I ask because I don't see where dPanel accesses anything with regard to menus. However, dForm and dApp do. And it easy to turn off if required. In your __main__ app = dabo.dApp() app.DefaultMenuBarClass='' ## turn off the menu bar With respect to the "ctrl -" and "ctrl +" causing issues for the UI sounds like a bug. It has worked for me on windows and linux without any trouble I'm aware of. What platform are you using, what version etc.. You can obtain the information by using the "about " from any Dabo program. -- John Fabiani _______________________________________________ Post Messages to: Dabo-users@leafe.com Subscription Maintenance: http://leafe.com/mailman/listinfo/dabo-users Searchable Archives: http://leafe.com/archives/search/dabo-users This message: http://leafe.com/archives/byMID/[EMAIL PROTECTED]
