An extended version of
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.
