Method Details

addTreeModelListener

public void addTreeModelListener(TreeModelListener listener)

Add a TreeModelListener to a read-only tree. Note that there is no book-keeping required for adding a TreeModelListener, as a read-only tree cannot change.

Specified by:

addTreeModelListener in interface TreeModel

Parameters:

listener - The listener to "add".

removeTreeModelListener

public void removeTreeModelListener(TreeModelListener listener)

Remove a TreeModelListener from a read-only tree. Note that there is no book-keeping required for adding a TreeModelListener, as a read-only tree cannot change.

Specified by:

removeTreeModelListener in interface TreeModel

Parameters:

listener - The listener to "remove".

valueForPathChanged

public void valueForPathChanged(TreePath path, Object newValue)

Indicate that the given path in the tree has changed. Note that since a read-only is immutable, this does nothing

Specified by:

valueForPathChanged in interface TreeModel

Parameters:

path - The path which changed.

newValue - The value of the new path.
