MDI Child property

For info windows, this is where you specify whether a window should behave as an MDI child or not.

•If a window behaves as an MDI child, it can only be moved within the borders of the parent window. If the child window is partly moved beyond these borders, it is clipped (part of it is no longer visible).

•If a window does not behave as an MDI child, it can be moved outside the borders of the parent window. This is standard behavior for modal windows. If you set a window's Modal behavior property to Yes, its MDI Child property is set to No automatically.

The MDI Child property has no effect on dialog windows.MenubarAddItem()
