Examples of java.beans.PropertyChangeSupport.firePropertyChange()

java.beans.PropertyChangeSupport.firePropertyChange()
Report a bound property update to any registered listeners. No event is fired if old and new are equal and non-null.
This is merely a convenience wrapper around the more general firePropertyChange method that takes {@code PropertyChangeEvent} value. @param propertyName The programmatic name of the propertythat was changed. @param oldValue The old value of the property. @param newValue The new value of the property.
