Examples of javax.swing.event.SwingPropertyChangeSupport.firePropertyChange()

javax.swing.event.SwingPropertyChangeSupport.firePropertyChange()
{@inheritDoc}
If {@link #isNotifyOnEDT} is {@code true} and called off theEvent Dispatch Thread this implementation uses {@code SwingUtilities.invokeLater} to send out the notificationon the Event Dispatch Thread. This ensures listeners are only ever notified on the Event Dispatch Thread. @throws NullPointerException if {@code evt} is{@code null} @since 1.6
