From class java.lang.Object

Object	clone() Creates and returns a copy of this object.
boolean	equals(Object obj) Indicates whether some other object is "equal to" this one.

int	hashCode() Returns a hash code value for the object.
final void	notify() Wakes up a single thread that is waiting on this object's monitor.
final void	notifyAll() Wakes up all threads that are waiting on this object's monitor.
String	toString() Returns a string representation of the object.
final void	wait() Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.
final void	wait(long timeout, int nanos) Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.

Public Methods

public abstract void cancelEditing (JTree tree)

Cancels the current editing session. This has no effect if the tree isn't being edited. Returns true if the editor allows the editing session to stop.

public abstract TreePath getClosestPathForLocation (JTree tree, int x, int y)

Returns the path to the node that is closest to x,y. If there is nothing currently visible this will return null, otherwise it'll always return a valid path. If you need to test if the returned object is exactly at x, y you should get the bounds for the returned path and test x, y against that.

public abstract TreePath getEditingPath (JTree tree)

Returns the path to the element that is being edited.

public abstract Rectangle getPathBounds (JTree tree, TreePath path)

Returns the Rectangle enclosing the label portion that the last item in path will be drawn into. Will return null if any component in path is currently valid.

public abstract TreePath getPathForRow (JTree tree, int row)

Returns the path for passed in row. If row is not visible null is returned.

public abstract int getRowCount (JTree tree)

Returns the number of rows that are being displayed.

public abstract int getRowForPath (JTree tree, TreePath path)

Returns the row that the last item identified in path is visible at. Will return -1 if any of the elements in path are not currently visible.

public abstract boolean isEditing (JTree tree)

Returns true if the tree is being edited. The item that is being edited can be returned by getEditingPath().

public abstract void startEditingAtPath (JTree tree, TreePath path)

Selects the last item in path and tries to edit it. Editing will fail if the CellEditor won't allow it for the selected item.

public abstract boolean stopEditing (JTree tree)

Stops the current editing session. This has no effect if the tree isn't being edited. Returns true if the editor allows the editing session to stop.
