Yes, but with the shift I described not such worry:
public void UpdateCorpusInfo()
{
var dlg = new ProgressDialog("My title");
var thread = new Thread (new ParameterizedThreadStart
(doUpdateCorpusInfo));
thread.Start(dlg);
}
private void doUpdateCorpusInfo(object _arg)
{
var dlg = (ProgressDialog)_arg;
try
{
Gtk.Application.Invoke (delegate{ dlg.Show(); });
// loading data and refreshing GUI (via Invoke)
}
finally
{
if (dlg!=null)
Gtk.Application.Invoke (delegate{ dlg.Destroy();});
}
}

There are examples, but all scattered all over the page, there is no
section (task oriented). So it was (for me at least) get the big
picture.
