libglade's glade_xml_signal_autoconnect() function assumes that the signal
data field is just a string, so it won't understand (int)45.

You could either use atoi() to convert to an integer, or you can set the
value based on the widget which received the signal, e.g.

   button1 = lookup_widget (widget, "button1");
   button2 = lookup_widget (widget, "button2");
   button3 = lookup_widget (widget, "button3");

   if (widget == button1)
     value = 45;
   else if (widget == button2)
     value = 50;
   else if (widget == button3)
     value = 55;
