Method Detail
firePropertyChange
public void firePropertyChange(PropertyChangeEvent evt)
Fires a property change event to listeners that have been registered to track updates of all properties or a property with the specified name.
No event is fired if the given event's old and new values are equal and non-null.
If isNotifyOnEDT()
is true
and called off the Event Dispatch Thread this implementation uses SwingUtilities.invokeLater
to send out the notification on the Event Dispatch Thread. This ensures listeners are only ever notified on the Event Dispatch Thread.
