public class JInternalFrame

extends JComponent

implements Accessible, WindowConstants, RootPaneContainer

A lightweight object that provides many of the features of a native frame, including dragging, closing, becoming an icon, resizing, title display, and support for a menu bar. Generally, you create an instance and add it to a JDesktopPane. Look and feel specific-actions are then (automatically??) delegated to the DesktopManager object maintained by the JDesktopPane (as set by the UI).

The JInternalFrame contentPane is where you add child components. So, to create a JInternalFrame that has a number of buttons arranged with a BorderLayout object, you might do something like this:

    JComponent c = (JComponent) frame.getContentPane();
    c.setLayout(new BorderLayout());
    c.add(new JButton(), BorderLayout.NORTH);
    c.add(new JButton(), BorderLayout.CENTER);
 

The contentPane is actually managed by an instance of JRootPane, which also manages a layoutPane, glassPane, and optional menuBar for the frame. Please see the JRootPane documentation for a complete description of these components.

For the keyboard keys used by this component in the standard Look and Feel (L&F) renditions, see the JInternalFrame key assignments.

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. A future release of Swing will provide support for long term persistence.

Removes the specified internal frame listener so that it no longer receives internal frame events from this internal frame.

Parameters:

l - the internal frame listener

fireInternalFrameEvent

setDefaultCloseOperation

public void setDefaultCloseOperation(int operation)

Sets the operation which will happen by default when the user initiates a "close" on this window. The possible choices are:

• DO_NOTHING_ON_CLOSE - do not do anything - require the program to handle the operation in the windowClosing method of a registered InternalFrameListener object.
• HIDE_ON_CLOSE - automatically hide the window after invoking any registered InternalFrameListener objects
• DISPOSE_ON_CLOSE - automatically hide and dispose the window after invoking any registered InternalFrameListener objects
• EXIT_ON_CLOSE - Exit the application by way of System.exit. Only use this in applications.

The value is set to HIDE_ON_CLOSE by default.
