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 conveniance add and its variants, remove and setLayout have been overridden to forward to the contentPane as necessary. This means you can write:
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:
internalFrame.add(child);
JComponent c = (JComponent) internalFrame.getContentPane();
c.add(new JButton(), BorderLayout.NORTH);
c.add(new JButton(), BorderLayout.CENTER);
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.
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

for details.
Ensures that, by default, children cannot be added directly to this component. Instead, children must be added to its content pane. For example:
thisComponent.getContentPane().add(child)
An attempt to add to directly to this component will cause a runtime exception to be thrown. Subclasses can disable this behavior.

public boolean isClosable()
-
Returns whether this JInternalFrame can be closed by some user action.
-
-
-
Returns:
-
true if this internal frame can be closed
isClosed
public boolean isClosed()
-
Returns whether this JInternalFrame is currently closed.
-
-
-
Returns:
-
true if this internal frame is closed, false otherwise
setClosed
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 be true
-
Throws:
-
PropertyVetoException
- when the attempt to set the property is vetoed by the JInternalFrame

When this method changes the state of the internal frame from deselected to selected, it fires an InternalFrameEvent.INTERNAL_FRAME_ACTIVATED event. If the change is from selected to deselected, an InternalFrameEvent.INTERNAL_FRAME_DEACTIVATED event is fired.
-

-
Parameters:

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

-
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.

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.
