addPropertyChangeListener

[IYIaster]

I'm trying to use a addPropertyChangeListener so I can use a progress bar to get the progress of a thread. Everything I try will not allow me to add a property change listener.

            
final install7 t = new install7();
new Thread(t).start();

The object that wants to fire PropertyChangeEvents to PropertyChangeListeners should have a PropertyChangeSupport member object. Listeners register themselves to this PropertyChangeSupport class (optionally with the name of the event they're interested in). Normally those classes that own the PropertyChangeSupport object have delegating add- and remove- propertyChangeListener methods because it's non of the listeners business how and where they are finally registered.

Read the API documentation for all the mentioned classes.

kind regards,
