Method Detail

firePropertyChange

public void firePropertyChange(PropertyChangeEvent evt)
Fire an existing PropertyChangeEvent to any registered listeners. No event is fired if the given event's old and new values are equal and non-null.

Parameters:
evt - The PropertyChangeEvent object.
Throws:
NullPointerException - if evt is null
Since:
1.6
