public class JApplet
extends Applet
implements Accessible, RootPaneContainer
Deprecated.
The Applet API is deprecated, no replacement.
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.

field:rootPane [NONE]

  • rootPane

    protected JRootPane rootPane
    Deprecated.
    See Also:
    getRootPane(), setRootPane(javax.swing.JRootPane)

    • field:rootPaneCheckingEnabled [NONE]

    rootPaneCheckingEnabled

    protected boolean rootPaneCheckingEnabled
    Deprecated.
    If true then calls to add and setLayout will be forwarded to the contentPane. This is initially false, but is set to true when the JApplet is constructed.
    See Also:
    isRootPaneCheckingEnabled(), setRootPaneCheckingEnabled(boolean), RootPaneContainer

    field:accessibleContext [NONE]

    accessibleContext

    protected AccessibleContext accessibleContext
    Deprecated.
    AccessibleContext associated with this JApplet

    constructor:JApplet() [NONE]

    method:createRootPane() [NONE]

  • createRootPane

    protected JRootPane createRootPane()
    Deprecated.
    Called by the constructor methods to create the default rootPane.
    Returns:
    a new JRootPane

    • method:setTransferHandler(javax.swing.TransferHandler) [NONE]

    setTransferHandler

    @BeanProperty(hidden=true, description="Mechanism for transfer of data into the component") public void setTransferHandler​(TransferHandler newHandler)
    Deprecated.
    Sets the transferHandler property, which is a mechanism to support transfer of data into this component. Use null if the component does not support data transfer operations.

    If the system property suppressSwingDropSupport is false (the default) and the current drop target on this component is either null or not a user-set drop target, this method will change the drop target as follows: If newHandler is null it will clear the drop target. If not null it will install a new DropTarget.

    Note: When used with JApplet, TransferHandler only provides data import capability, as the data export related methods are currently typed to JComponent.

    Please see How to Use Drag and Drop and Data Transfer , a section in The Java Tutorial , for more information.

    Parameters:
    newHandler - the new TransferHandler
