How handle long operation with UI report on RCP close?

When closing my Eclipse (for plugin development) workbench while a long operation is running in 开发者_运维问答my workbench (and thus reported to me through the progress view) such as a "Clean all" action the following happen:

1. the main workbench window is closed
2. a new small window (a dialog I guess) is opened with the same content than the previous progress view. This dialog informs me that some operations are being completed before actually closing the application

How can I achieve the same behavior in an RCP application with my own Jobs running long operations ?

Thansk for your help, Manu

What about looking in the eclipse-IDE code to see how its implemented ;) Small advice:

org.eclipse.ui.internal.ide.application.IDEWorkbenchAdvisor.postShutdown()

in bundle

org.eclipse.ui.ide.application
