Examples of org.eclipse.swt.events.DisposeListener

org.eclipse.swt.events.DisposeListener
Classes which implement this interface provide a method that deals with the event that is generated when a widget is disposed.
After creating an instance of a class that implements this interface it can be added to a widget using the addDisposeListener method and removed using the removeDisposeListener method. When a widget is disposed, the widgetDisposed method will be invoked.
