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.
