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><DL><DT><B>See Also: </B><DD><A HREF="../../javax/swing/JDesktopPane.html"><CODE>JDesktopPane</CODE></A>, <A
