@Deprecated(since="9") @JavaBean(defaultProperty="JMenuBar", description="Swing\'s Applet subclass.") public class JApplet extends Applet implements Accessible, RootPaneContainer
Deprecated.The Applet API is deprecated, no replacement.An extended version ofjava.applet.Appletthat adds support for the JFC/Swing component architecture. You can find task-oriented documentation about usingJAppletin The Java Tutorial, in the section How to Make Applets.The
JAppletclass is slightly incompatible withjava.applet.Applet.JAppletcontains aJRootPaneas its only child. ThecontentPaneshould be the parent of any children of theJApplet. As a convenience, theadd,remove, andsetLayoutmethods of this class are overridden, so that they delegate calls to the corresponding methods of theContentPane. For example, you can add a child component to an applet as follows:applet.add(child);And the child will be added to thecontentPane. ThecontentPanewill always be non-null. Attempting to set it tonullwill cause theJAppletto throw an exception. The defaultcontentPanewill have aBorderLayoutmanager set on it. Refer toRootPaneContainerfor details on adding, removing and setting theLayoutManagerof aJApplet.Please see the
JRootPanedocumentation for a complete description of thecontentPane,glassPane, andlayeredPaneproperties.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.beanspackage. Please seeXMLEncoder.- Since:
- 1.2
