Class TreeSelectionEvent

java.lang.Object
  java.util.EventObject
      javax.swing.event.TreeSelectionEvent

All Implemented Interfaces:

Serializable

public class TreeSelectionEvent
extends EventObject

Disabled: no SafeJ information.

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)

Class is disabled.

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)

Class is disabled.

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()

Class is disabled.

Returns the paths that have been added or removed from the selection.

getPath

public TreePath getPath()

Class is disabled.

Returns the first path element.

isAddedPath

public boolean isAddedPath()

Class is disabled.

Returns whether the path identified by getPath was added to the selection. A return value of true indicates the path identified by getPath was added to the selection. A return value of false indicates getPath was selected, but is no longer selected.

Returns:

true if getPath was added to the selection, false otherwise

isAddedPath

public boolean isAddedPath(TreePath path)

Class is disabled.

Returns whether the specified path was added to the selection. A return value of true indicates the path identified by path was added to the selection. A return value of false indicates path is no longer selected. This method is only valid for the paths returned from getPaths(); invoking with a path not included in getPaths() throws an IllegalArgumentException.

Parameters:

path - the path to test

Returns:

true if path was added to the selection, false otherwise

Throws:

IllegalArgumentException - if path is not contained in getPaths

See Also:

getPaths()

isAddedPath

public boolean isAddedPath(int index)

Class is disabled.

Returns whether the path at getPaths()[index] was added to the selection. A return value of true indicates the path was added to the selection. A return value of false indicates the path is no longer selected.

Parameters:

index - the index of the path to test

Returns:

true if the path was added to the selection, false otherwise

Throws:

IllegalArgumentException - if index is outside the range of getPaths

Since:

1.3

public TreePath getNewLeadSelectionPath()

Class is disabled.

Returns the current lead path.

cloneWithSource

public Object cloneWithSource(Object newSource)

Class is disabled.

Returns a copy of the receiver, but with the source being newSource.
