public class DesktopContext
DesktopContext is an application context that displays multiple content panes in an instance of a JDesktopPane. It also contains a menubar, toolbar, and a status bar. When created, it is not visible, so the caller must call setVisible(true) to make it appear on the screen.
The implementation of JDesktopPane in Swing is not really quite what we want in a frame of this type, so there are various listeners attached to the JDesktopPane and the internal components that resize and reparent components in a more useful way.
Each "content pane" that is added to this frame is added by default to a JInternalFrame. However, the pane may be removed from the pane, either by the JDesktopPane when it is iconified, or by this class when the internal frame is maximized. Hence, users of this class should not rely on the content pane actually being contained by the internal frame that it is associated with.
MDI applications often contain multiple toolbars. This class implements a toolbar pane that contains the basic toolbar, along with any other toolbars in the application.
