[news.eclipse.platform.swt] How to fire PropertyChangeEvent?

[webapp@xxxxxx (Rudolf Schmidt)]

Hi,

I want to notify some gui composites about state changes in my model 
(Bean). I found the JFace ListenerList class which I may use to store 
listeners in the bean and also I found PropertyChangeEvent that I could 
use as message.

My question is how to fire the event? Do I have to use Display.postEvent() 
or do I have to iterate over the listeners stored in the listenerslist?

Thanks, Rudolf
