fireChanged

public void fireChanged(boolean propagate)

Called when the element has changed.

Specified by:

fireChanged in interface ChangeTrackingInterface

Parameters:

propagate - if set to true, change is also fired on parent and registered listeners.

fires a change on this element and all its children, but no listeners and parents.

Specified by:

fireChangeForSubTree in interface ChangeTrackingInterface

changeHook

protected void changeHook()

Called on any change. Please override!

addListener

public void addListener(ChangeTrackingInterface listener)

Adds a change listener to this element.

Specified by:

addListener in interface ChangeTrackingInterface

Parameters:

listener - the element to be notified in case of changes (if propagate is set).
