What is probably better is to use gdk_flush() after the execution of
gtk_window_move() or _resize(), and after that make sure that you run the
main event loop with gtk_main_iteration(); you can use a GTimer to determine
the time elapsed. Obviously, and also since this involves the windowing
system whose timing can not really be predicted, this is nothing for time
critical applications and can't be very precise, but tweaks of the mentioned
mechanism are surely possible.
An example would look like this (off the top of my head, might contain some
errors):
GTimer *timer = g_timer_new();
gtk_window_move(GTK_WINDOW(window), x, y);
g_timer_reset(timer);
while(g_timer_elapsed(timer) > 0.5)
while(gtk_events_pending())
gtk_main_iteration();
g_timer_destroy(timer);
Hopefully someone has a more elegant solution :)
