Class AncestorEvent

Contents
  • All Implemented Interfaces:
    Serializable

    public class AncestorEvent
extends AWTEvent
    An event reported to a child component that originated from an ancestor in the component hierarchy.

    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 JavaBeansTM has been added to the java.beans package. Please see XMLEncoder.

        public static final int ANCESTOR_ADDED
        An ancestor-component was added to the hierarchy of visible objects (made visible), and is currently being displayed.

        Constant Field Values

      • ANCESTOR_REMOVED

        public static final int ANCESTOR_REMOVED
        An ancestor-component was removed from the hierarchy of visible objects (hidden) and is no longer being displayed.
        See Also:
        Constant Field Values

      • ANCESTOR_MOVED

        public static final int ANCESTOR_MOVED
        An ancestor-component changed its position on the screen.

    • Constructor Detail

      • AncestorEvent

        public AncestorEvent(JComponent source,
             int id,
             Container ancestor,
             Container ancestorParent)
        Constructs an AncestorEvent object to identify a change in an ancestor-component's display-status.
        Parameters:
        source - the JComponent that originated the event (typically this)
        id - an int specifying ANCESTOR_ADDED, ANCESTOR_REMOVED or ANCESTOR_MOVED
        ancestor - a Container object specifying the ancestor-component whose display-status changed
        ancestorParent - a Container object specifying the ancestor's parent

    • Method Detail

      • getAncestor

        public Container getAncestor()
        Returns the ancestor that the event actually occurred on.

      • getAncestorParent

        public Container getAncestorParent()
        Returns the parent of the ancestor the event actually occurred on. This is most interesting in an ANCESTOR_REMOVED event, as the ancestor may no longer be in the component hierarchy.

      • getComponent

        public JComponent getComponent()
        Returns the component that the listener was added to.
