How do I add a listener to a graphics object being deleted? It seems like 'BeingDeleted' is set to 'on' during deletion. Furthermore 'BeingDeleted' is SetObservable. So why does the following code not work?
h=plot(0,0,'.b');
addlistener(h,'BeingDeleted','PostSet',@(varargin)(disp('deleted')))
delete(h)
Please note I don't want to use the callback 'deleteFcn', since there might be other objects interested in the delete event.

I'm also having trouble with listeners to 'BeingDeleted'. Did you find a work around?

How about just listening for 'ObjectBeingDestroyed'?
addlistener(h,'ObjectBeingDestroyed',@(varargin)(disp('deleted')))
