Class TreeSelectionEventjava.lang.Object | +--java.util.EventObject | +--javax.swing.event.TreeSelectionEvent
- All Implemented Interfaces:
- Serializable
- public class TreeSelectionEvent
- extends 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 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.

Constructor Detail
TreeSelectionEvent
public TreeSelectionEvent(Object source, TreePath[] paths, boolean[] areNew, TreePath oldLeadSelectionPath, TreePath newLeadSelectionPath)
- Represents a change in the selection of a TreeSelectionModel. paths identifies the paths that have been either added or removed from the selection.
- Parameters:
- source - source of event
- paths - the paths that have changed in the selection
TreeSelectionEvent
public TreeSelectionEvent(Object source, TreePath path, boolean isNew, TreePath oldLeadSelectionPath, TreePath newLeadSelectionPath)
- Represents a change in the selection of a TreeSelectionModel. path identifies the path that have been either added or removed from the selection.
- Parameters:
- source - source of event
- path - the path that has changed in the selection
- isNew - whether or not the path is new to the selection, false means path was removed from the selection.
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.
isAddedPath
public boolean isAddedPath(int index)
- Returns true if the path identified by index 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 index < 0 || >= getPaths.length.
- Since:
- 1.3
getOldLeadSelectionPath
public TreePath getOldLeadSelectionPath()
- Returns the path that was previously the lead path.
getNewLeadSelectionPath
public TreePath getNewLeadSelectionPath()
- Returns the current lead path.
cloneWithSource
public Object cloneWithSource(Object newSource)
- Returns a copy of the receiver, but with the source being newSource.
