Class TransitionBorder

java.lang.Object
  org.jvnet.lafwidget.layout.TransitionBorder

All Implemented Interfaces:

javax.swing.border.Border

Direct Known Subclasses:

TransitionBorder.BorderUIResource

public class TransitionBorder
extends java.lang.Object
implements javax.swing.border.Border

Border implementation that respects the transition composite effects set by the TransitionLayout. All Borders installed on the component hierarchy are wrapped in instances of this class once the TransitionLayout is installed on that component (with TransitionLayoutManager.track(Container, boolean) or TransitionLayoutManager.track(Container, boolean, boolean).

Note that installing the TransitionLayout on a component may break applications that operate directly on the installed borders, resulting in ClassCastException or incorrect logic being called. The relevant code needs to be changed using the getDelegate(). In addition, the applications will get PropertyChangeEvents when these borders are set / unset.
