Thanks,
I've read this topic, but didn't realize, that signal received within the
Gtk.Application isn't thread safe.
The easiest way was (as I suppose) is:
if(Changed != null)
Gtk.Application.Invoke(delegate { Changed("u"); });
or catch the signal in MainWindow.OnChanged() and execute second function (or
code) with G.A.Invoke.
The second approach is, as I think, more correct, because it does not make
Thread class Gtk dependent. The first is "write and forget" - You don't have to
remember about G.A.Invoke and writing delegates.
Regards,
Piotr
