+/** 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>
