[Gtk-sharp-list] How to show custom window and do the computation in the background

[David S]

I dont know how you are doing the actual loading but I hope you are doing it
like this.

Create Dialog
Create BackgroundWorker.
Set BackgroundWorker DoWork function making sure to set the progress and
call ReportProgress.
Set BackgroundWorker ReportProgress function making sure all calls to gtk
are Gtk.Application.Invoke.
Show Dialog.
Run BackgroundWorker.

If not, you are probably loading in the thread that GTK is using to actually
update.
