Class TreeSelectionEvent

java.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 JavaBeans^TM 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.
