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. As a convenience, the add, remove, and setLayout methods of this class are overridden, so that they delegate calls to the corresponding methods of the ContentPane. For example, you can add a child component to an internal frame as follows:
internalFrame.add(child);And the child will be added to the contentPane. 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. Refer to RootPaneContainer for details on adding, removing and setting the LayoutManager of a JInternalFrame. Warning: Swing is not thread safe. For more information see Swing's Threading Policy.
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™ has been added to the java.beans package. Please see XMLEncoder.

setClosed
@BeanProperty(description="Indicates whether this internal frame has been closed.")
public void setClosed(boolean b)
throws PropertyVetoException Closes this internal frame if the argument is true. Do not invoke this method with a false argument; the result of invoking setClosed(false) is unspecified.
If the internal frame is already closed, this method does nothing and returns immediately. Otherwise, this method begins by firing an INTERNAL_FRAME_CLOSING event. Then this method sets the closed property to true unless a listener vetoes the property change. This method finishes by making the internal frame invisible and unselected, and then firing an INTERNAL_FRAME_CLOSED event.
Note: To reuse an internal frame that has been closed, you must add it to a container (even if you never removed it from its previous container). Typically, this container will be the JDesktopPane that previously contained the internal frame.
- Parameters:
-
b- must betrue - Throws:
-
PropertyVetoException- when the attempt to set the property is vetoed by theJInternalFrame - See Also:

Fires an INTERNAL_FRAME_CLOSING event and then performs the action specified by the internal frame's default close operation. This method is typically invoked by the look-and-feel-implemented action handler for the internal frame's close button.
- Since:
- 1.3
- See Also:
-
setDefaultCloseOperation(int),InternalFrameEvent.INTERNAL_FRAME_CLOSING
setDefaultCloseOperation
public void setDefaultCloseOperation(int operation)
Sets the operation that will happen by default when the user initiates a "close" on this internal frame. The possible choices are:
-
DO_NOTHING_ON_CLOSE - Do nothing. This requires the program to handle the operation in the
internalFrameClosingmethod of a registeredInternalFrameListenerobject. -
HIDE_ON_CLOSE - Automatically make the internal frame invisible.
-
DISPOSE_ON_CLOSE - Automatically dispose of the internal frame.
The default value is DISPOSE_ON_CLOSE. Before performing the specified close operation, the internal frame fires an INTERNAL_FRAME_CLOSING event.
- Parameters:
-
operation- one of the following constants defined injavax.swing.WindowConstants(an interface implemented byJInternalFrame):DO_NOTHING_ON_CLOSE,HIDE_ON_CLOSE, orDISPOSE_ON_CLOSE - See Also:
-
addInternalFrameListener(javax.swing.event.InternalFrameListener),getDefaultCloseOperation(),JComponent.setVisible(boolean),dispose(),InternalFrameEvent.INTERNAL_FRAME_CLOSING

pack
public void pack()
Causes subcomponents of this JInternalFrame to be laid out at their preferred size. Internal frames that are iconized or maximized are first restored and then packed. If the internal frame is unable to be restored its state is not changed and will not be packed.
- See Also:
Window.pack()
show
public void show()
If the internal frame is not visible, brings the internal frame to the front, makes it visible, and attempts to select it. The first time the internal frame is made visible, this method also fires an INTERNAL_FRAME_OPENED event. This method does nothing if the internal frame is already visible. Invoking this method has the same result as invoking setVisible(true).
- Overrides:
-
showin classComponent - See Also:
-
moveToFront(),setSelected(boolean),InternalFrameEvent.INTERNAL_FRAME_OPENED,JComponent.setVisible(boolean)
dispose
public void dispose()
Makes this internal frame invisible, unselected, and closed. If the frame is not already closed, this method fires an INTERNAL_FRAME_CLOSED event. The results of invoking this method are similar to setClosed(true), but dispose always succeeds in closing the internal frame and does not fire an INTERNAL_FRAME_CLOSING event.
- See Also:
-
InternalFrameEvent.INTERNAL_FRAME_CLOSED,JComponent.setVisible(boolean),setSelected(boolean),setClosed(boolean)
toFront
public void toFront()
Brings this internal frame to the front. Places this internal frame at the top of the stacking order and makes the corresponding adjustment to other visible internal frames.
- See Also:
-
Window.toFront(),moveToFront()

- 1.4
- See Also:
-
isFocusCycleRoot(),Container.setFocusTraversalPolicy(java.awt.FocusTraversalPolicy),Container.getFocusTraversalPolicy()

null- Since:
- 1.4
- See Also:
Container.isFocusCycleRoot()
getWarningString
@BeanProperty(bound=false) public final String getWarningString()
