Examples of org.eclipse.jface.util.PropertyChangeEvent

org.eclipse.jface.util.PropertyChangeEvent
An event object describing a change to a named property.
This concrete class was designed to be instantiated, but may also be subclassed if required.

The JFace frameworks contain classes that report property change events for internal state changes that may be of interest to external parties. A special listener interface (IPropertyChangeListener) is defined for this purpose, and a typical class allow listeners to be registered via an addPropertyChangeListener method.
