How to force the refresh of a GTKTreeView in a multithreaded app?

[Álvaro Palma <apalma opschile cl>]

I've developed a very simple application in GTK2. This application 
receives events from a socket and based on them, updates the values in a 
GTKTreeView.

The problem that arises is that the items displayed in the TreeView are 
not updated until I move the mouse.

The application is something like this:


main()
{
  g_thread_init (NULL);
  gdk_threads_init ();
  gdk_threads_enter ();
  gtk_init (&argc, &argv);

  ...

  // Create the window Widget
  createWindow(gtkWindow);
  createThread(SocketEvents);  // NOTICE THIS, A NEW THREAD IS CREATED
                               // TO UPDATE THE GUI
  gtk_widget_show_all(gtkWindow);
  ...

  gtk_main();
  gdk_threads_leave ();
}

and inside the SocketEvents thread function, I update the GTKListStore 
associated to the GTKTreeView with no luck. The code looks like this:

SocketEvents()
{
  ...
  while(1){
    <receive an event from a socket>
    ....
    gdk_threads_enter();
    gtk_list_store_set(....);
    gtk_widget_queue_draw(GTK_WIDGET(gtkTreeView));
    while (gtk_events_pending ())
      gtk_main_iteration ();
    gdk_threads_leave();
  }
}

However, in this case, I receive the following error:

(MyAPP:12142): GLib-WARNING **: g_main_context_prepare(): main loop 
already active in another thread
Xlib: unexpected async reply (sequence 0x1ee7)!

GLib-ERROR **: file gmain.c: line 1906 (g_main_dispatch): assertion 
failed: (source)
aborting...

Can anybody give me a clue about how do I have to update the list store
to be able to see my changes reflected in the screen right away?

Thanks a lot for your attention and help.
