Is the job blocking? If not, and you have time in the run method, you
can show it, or fire off an event to a listener who could show it.
Otherwise it'd be a bit odd to have a property on the job of a method to
call "some time" during the job.

Hi Stefan,
in my example, what you suggest fails because getActiveWorkbenchWindow()
returns null.
I'm beginning to think that the only way round this is to use a view
instead of Dialog (ie something that stays active in the workbench), but
that's not bulletproof either, as it's unlikely, but not impossible that
the user closes the view, unless I can find a way to prevent that.
What's the normal thing to do when you just want to get a shell in order
to show a dialog or something?

Create a dialog without a shell. As far as I know when you pass in null
the dialog simply creates its own shell. This has the drawback that when
the dialog is modal it might dissapear behind other windows in certain
cases and the user won'T see it anymore but the UI is still unresponsive.
Another solution is to simply create your own shell and pass that in.
Regards
Stefan
