/// TMDIChild defines the basic behavior of all MDI child windows. Child windows can
/// be created inside the client area of a parent window. Because child windows
/// exist within, and are restricted to the parent window's borders,  the parent
/// window defined before the child is defined. For example, a dialog box is a
/// window that contains child windows, often referred to as dialog box controls.
///
/// To be used as MDI children, classes must be derived from TMDIChild. MDI children
/// can inherit keyboard navigation, focus handling, and icon support from
/// TFrameWindow. TMDIChild is a streamable class.
