/**
* The MDI client window manages a number of MDI child windows in
* a multiple-document interface (MDI) application.
* MDI child windows usually receive messages from the GUI through
* delegation via the MDI client, i.e. the MDI client window is set as
* the target for most GUI commands; the MDI client filters out a few messages
* and forwards all other messages to the active MDI child.
* MDI client can arrange the MDI child windows in various ways:-
* it may maximize one of the MDI child windows, arrange them side-by-side,
* cascade them, or iconify them.
* MDI child windows are notified about changes in the active MDI child
* window by the MDI client.
