Class diagram for nested managers
The following UML class diagram summarizes the class structure for nested managers.
IlvManager is a subclass of IlvGraphic ; since IlvManager can contain IlvGraphic instances as objects, it is possible to nest managers in other managers. When you display the nested submanagers, the content is drawn and transformed using a local IlvTransformer instance in the submanager. For the top-level manager displayed in the manager view, the local transformer plays no role since the top-level manager is drawn and transformed by that view’s IlvTransformer.
A manager can be collapsed or expanded. In its collapsed state, it is drawn as a representative collapsed graphic and its contents are not drawn. In its expanded state, its contents are drawn inside a manager frame.
