Class com.sun.java.swing.event.TreeSelectionEvent

java.lang.Object
  |
  +--java.util.EventObject
        |
        +--com.sun.java.swing.event.TreeSelectionEvent

public class TreeSelectionEvent
extends java.util.EventObject
An event that characterizes a change in the current selection. The change is based on any number of paths. TreeSelectionListeners will generally query the source of the event for the new selected status of each potentially changed row.

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 Swing1.0 applications. It will not be possible to load serialized Swing1.0 objects with future releases of Swing. The JDK1.2 release of Swing will be the compatibility baseline for the serialized form of Swing objects.

TreeSelectionEvent

public TreeSelectionEvent(java.lang.Object source,
                          TreePath path,
                          boolean isNew,

Method Detail

getPaths

public TreePath[] getPaths()
Returns the paths that have been added or removed from the selection.

getPath

public TreePath getPath()
Returns the first path element.

isAddedPath

public boolean isAddedPath()
Returns true if the first path element has been added to the selection, a return value of false means the first path has been removed from the selection.

isAddedPath

public boolean isAddedPath(TreePath path)
Returns true if the path identified by path was added to the selection. A return value of false means the path was in the selection but is no longer in the selection. This will raise if path is not one of the paths identified by this event.

getOldLeadSelectionPath

public TreePath getOldLeadSelectionPath()
Returns the path that was previously the lead path.

getNewLeadSelectionPath

public TreePath getNewLeadSelectionPath()
Returns the current lead path.

cloneWithSource

public java.lang.Object cloneWithSource(java.lang.Object newSource)
Returns a copy of the receiver, but with the source being newSource.
