best to think of some other model. gobject signals do not (trivially)
cross thread boundaries. the most widely adopted approach is to use
g_idle_add() to (thread-safely) add an idle callback that emits the
signal from the correct (g_main_loop()) thread:
gboolean foobar (gpointer foo) {
g_signal_emit_by_name (foo, signal-name);
return FALSE;
}
in thread T2:
...
g_idle_add (foobar, G_OBJECT);
...
something like that, anyway.
