How to interrupt Eclipse RCP shutdown

I have a plugin into an eclipse r开发者_运维技巧cp application. I need to detect a scenario whenever a particular perspective is closed or if the application is closed and based on the outcome, I may need to cancel the closing of the app or perspective. If I had access to the application's WorkbenchAdvisor class, this would be trivial. As a plugin to this app, how can I detect the event and how can I tell the main application/advisor that I need to have the close canceled?

Have you looked at installing an IWorkbenchListener and extending the preShutdown method? It appears you can veto a shutdown using this mechanism.

I think want you want to do is not possible. If a plug-in could prevent an rcp application to shut down (or the other way force it to should down) this can be a serious security problem. Also the app state would be unclear as it might has released some resources.

If an app wants to give control of program termination to a plug-in it should define an interface/extension point that can be used.
