Can someone tell me what listeners are available on the display.


I noticed that there is a DisposeListener for the shell, but I would
prefer to detect that the program is no longer in use by some sort of
listener on the display (since I will have shells that come and go). A
sort of "no more active shells" listener.

Is that possible?

From the Javadoc for class Display:

* <dt><b>Events:</b></dt>
* <dd>Close, Dispose</dd>

Neither of these display events will help you. You'll have to count the
shells yourself as you create them and decrement your count in an SWT.Close
or SWT.Dispose listener for each shell.
