Hello, I tested the "TAdvOfficeMDITabSet component" version 2.5.0 with the associated Delphi demo, but I could not get the closed list button working. I assigned the "ClosedListMenu" a TAdvPopupMenu and activated the ClosedListButton, but no success. Does anybody know how the new Tab undock feature works? Do I have to do some action in the OnTabUnDock Event handler?

Best Regards,


AdvOfficeMDITabSet is derived from AdvOfficeTabset where ClosedListButton only works when tab visible is set to false, But here Delphi does not allow to hide MDI child form.
You need set AllowTabUndock = true and handle Undocked tab using OnTabUndock event.
