WINDOWS

Summary:

The Microsoft Windows implementation of the multiple document

interface (MDI) does not support nested MDI client windows. In other

words, neither an MDI client window nor an MDI child window can have

an MDI client window as a child.

More Information:

A Windows MDI client window is a member of the MDIClient window class,

and the Windows MDI model assumes that the parent of an MDIClient

window is a top-level frame window with a valid menu bar. This

assumption is necessary to implement the basic functionality defined

by the MDI interface, and it precludes the possibility of using nested

MDIClient windows. However, an application can have multiple top-level

windows, and each top-level window can have a separate MDIClient

window as a child.
