An MDI client window is a child of wxMDIParentFrame, and manages zero or more wxMDIChildFrame objects.

The client window is the area where MDI child windows exist. It doesn't have to cover the whole parent frame; other windows such as toolbars and a help window might coexist with it. There can be scrollbars on a client window, which are controlled by the parent window style.

The wxMDIClientWindow class is usually adequate without further derivation, and it is created automatically when the MDI parent frame is created. If the application needs to derive a new class, the function wxMDIParentFrame::OnCreateClient() (not implemented in wx) must be overridden in order to give an opportunity to use a different class of client window.

Under wxMSW, the client window will automatically have a sunken border style when the active child is not maximized, and no border style when a child is maximized.

This class is derived (and can use functions) from: wxWindow wxEvtHandler
