I assume here you mean that it is not thread-safe.
Regardless, you can simulate this by using the provided Gtk.Application.Invoke:
void ThreadEntryPoint() {
// do stuff...
Application.Invoke(delegate {
// do stuff with widgets
});
// do more stuff...
}
The call is not synchronous, and will return immediately. The
delegate will be executed at some point later on the main thread. If
you need a synchronous version:
void SynchronousInvoke(EventHandler e) {
ManualResetEvent ev = new ManualResetEvent(false);
Application.Invoke(delegate(object o, EventArgs args) {
e(o, args);
ev.Set();
}
ev.WaitOne();
}
It's not a terribly efficient method but if you're not making these
calls that often the performance should be fine.
