@Deprecated(since="9") @JavaBean(defaultProperty="JMenuBar", description="Swing\'s Applet subclass.") public class JApplet extends Applet implements Accessible, RootPaneContainer
java.applet.Applet
that adds support for
the JFC/Swing component architecture.
You can find task-oriented documentation about using JApplet
in The Java Tutorial,
in the section
How to Make Applets.
The JApplet
class is slightly incompatible with
java.applet.Applet
. JApplet
contains a
JRootPane
as its only child. The contentPane
should be the parent of any children of the JApplet
.
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 applet as follows:
applet.add(child);And the child will be added to the
contentPane
.
The contentPane
will always be non-null
.
Attempting to set it to null
will cause the
JApplet
to throw an exception. The default
contentPane
will have a BorderLayout
manager set on it.
Refer to RootPaneContainer
for details on adding, removing and setting the LayoutManager
of a JApplet
.
Please see the JRootPane
documentation for a
complete description of the contentPane
, glassPane
,
and layeredPane
properties.
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

setTransferHandler
@BeanProperty(hidden=true, description="Mechanism for transfer of data into the component") public void setTransferHandler(TransferHandler newHandler)Deprecated.Sets thetransferHandler
