Action-cancelling dialog box

Hi

Can somebody tell me how to make a dialog box like in iTunes when it imports new tracks. That is small window which disables all application except of the <Canel> button while the application does some actions.

As far as I can understand this dialog box is programmatically created and I don't need to design it it Iterface Builder. (I would be stupid to make in in IB for every other situation like this...)

So I wonder how can I create the behavior like that in my own application.

Maybe some sample code is available. Will be very grateful.

Thanks.
Vic.
