Hi Gurbhej,
The Menus framework automatically handles merging in an MDI situation. To so, simply add a MainFrameBarManager to the MDI container and a ChildFrameBarManager to the MDI child. While the MDI child is active, its bars will merge with the parent''s bars.
You can also refer to our online documentation for
MDI Merging. If you have any questions, please don''t hesitate to ask.
