- public class TreeSelectionEvent
- extends EventObject
- implements Cloneable
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.

protected boolean[] areNew
- For each path identifies if that is path is in fact new.
oldLeadSelectionPath

- leadSelectionPath before the paths changed, may be null.

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