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.
