Detailed Description
the base class for objects associated with a canvas item.
The ItemClient class is a base class used to associate document objects to items in the canvas. The associated item might be a Group, and the client might be registered for all group children. If several items are associated to the same object, the m_Item member should be the toplevel group. Destroying an ItemClient instance will destroy the item.
