There may be multiple MDI parent frames in a single application, but this probably only makes sense
within programming development environments.
-Child frames may be either \helpref{wxMDIChildFrame}{wxmdichildframe}, or \helpref{wxFrame}{wxframe}.
+Child frames may be of class \helpref{wxMDIChildFrame}{wxmdichildframe} (contained
+within the parent frame) or \helpref{wxFrame}{wxframe} (shown as a top-level frame).
An MDI parent frame always has a \helpref{wxMDIClientWindow}{wxmdiclientwindow} associated with it, which
is the parent for MDI client frames.
\helpref{wxMDIParentFrame::GetToolBar}{wxmdiparentframegettoolbar},\rtfsp
\helpref{wxMDIParentFrame::SetToolBar}{wxmdiparentframesettoolbar},\rtfsp
-\helpref{wxWindow}{wxwindowonsize},\rtfsp
\helpref{wxMDIClientWindow}{wxmdiclientwindow}
Note that it is probably impossible to have a client window that scrolls as well as painting
a bitmap or pattern, since in {\bf OnScroll}, the scrollbar positions always return zero.
