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™ has been added to the java.beans package. Please see XMLEncoder.
TreeSelectionListener, TreeSelectionModel
protected TreePath[] paths
Paths this event represents.
protected boolean[] areNew
For each path identifies if that path is in fact new.
protected TreePath oldLeadSelectionPath
leadSelectionPath before the paths changed, may be null.
protected TreePath newLeadSelectionPath
leadSelectionPath after the paths changed, may be null.
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.
source - source of eventpaths - the paths that have changed in the selectionpublic 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.
source - source of eventpath - the path that has changed in the selectionisNew - whether or not the path is new to the selection, false means path was removed from the selection.public TreePath[] getPaths()
Returns the paths that have been added or removed from the selection.
public TreePath getPath()
Returns the first path element.
public boolean isAddedPath()
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.
true if getPath was added to the selection, false otherwisepublic boolean isAddedPath(TreePath path)
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.
path - the path to testtrue if path was added to the selection, false otherwiseIllegalArgumentException - if path is not contained in getPaths
getPaths()public boolean isAddedPath(int index)
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.
index - the index of the path to testtrue if the path was added to the selection, false otherwiseIllegalArgumentException - if index is outside the range of getPaths
getPaths()public TreePath getOldLeadSelectionPath()
Returns the path that was previously the lead path.
public TreePath getNewLeadSelectionPath()
Returns the current lead path.
public Object cloneWithSource(Object newSource)
Returns a copy of the receiver, but with the source being newSource.
