Or, better, leave the signal handler as-is and use g_signal_connect rather than g_signal_connect_swapped. The latter is really for a case where the signal handler takes a widget as its first parameter and you want to pass it a different widget to the one that emits the signal, which you can pass as the data to g_signal_connect_swapped. So for the above example, there's no reason to use g_signal_connect_swapped.
