The standard way to connect a handler for a signal is:

   g_signal_connect (button, "clicked", on_button_clicked, user_data);

on_button_clicked() will then be called with button as the first argument.



However, if you want another object to be the first argument, you set the
'Object:' field in Glade. Then g_signal_connect_swapped() will be output,
and the object will be the first argument to the handler function.

Basically the 'Object:' field is too confusing so just avoid it.
