Class JInternalFrame

java.lang.Object
  java.awt.Component
      java.awt.Container
          javax.swing.JComponent
              javax.swing.JInternalFrame

All Implemented Interfaces:: Accessible, ImageObserver, MenuContainer, RootPaneContainer, Serializable, WindowConstants

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. For task-oriented documentation and examples of using internal frames, see How to Use Internal Frames, a section in The Java Tutorial.

Generally, you add JInternalFrames to a JDesktopPane. The UI delegates the look-and-feel-specific actions to the DesktopManager object maintained by the JDesktopPane.

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

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

The content pane is actually managed by an instance of JRootPane, which also manages a layout pane, glass pane, and optional menu bar for the internal 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 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. As of 1.4, support for long term storage of all JavaBeans^TM has been added to the java.beans package. Please see XMLEncoder.
