Class SwingPropertyChangeSupport

All Implemented Interfaces:
Serializable
public final class SwingPropertyChangeSupport
extends PropertyChangeSupport

This subclass of java.beans.PropertyChangeSupport is almost identical in functionality. The only difference is if constructed with SwingPropertyChangeSupport(sourceBean, true) it ensures listeners are only ever notified on the Event Dispatch Thread.

Methods

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.

Overrides:
firePropertyChange in class PropertyChangeSupport
Parameters:
evt - the PropertyChangeEvent to be fired
Throws:
NullPointerException - if evt is null
Since:
1.6

isNotifyOnEDT
