public class JInternalFrame
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 JInternalFrame
s 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:
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 JavaBeansTM
has been added to the java.beans
package.

If the internal frame is already closed,
this method does nothing and returns immediately.
Otherwise,
this method begins by firing
an INTERNAL_FRAME_CLOSING

Then this method sets the closed

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

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.
