/** DesktopManager objects are owned by a JDesktopPane object. They are responsible
* for implementing L&F specific behaviors for the JDesktopPane. JInternalFrame
* implementations should delegate specific behaviors to the DesktopManager. For
* instance, if a JInternalFrame was asked to iconify, it should try:
* <PRE>
* getDesktopPane().getDesktopManager().iconifyFrame(frame);
* </PRE>
* This delegation allows each L&F to provide custom behaviors for desktop-specific
* actions. (For example, how and where the internal frame's icon would appear.)
* <p>This class provides a policy for the various JInternalFrame methods, it is not
* meant to be called directly rather the various JInternalFrame methods will call
* into the DesktopManager.</p>
