No, I'm connecting to "clicked" :

    button = gtk_button_new_with_label ("Delete");
    gtk_signal_connect (GTK_OBJECT(button), "clicked",
                        (GtkSignalFunc) delete_callback,
                        NULL);
and:

    void delete_callback (GtkWidget *widget, gpointer data)
    {
        [..]

        delete_the_item();
        if (number_of_items == 0)
          gtk_widget_set_sensitive (widget, FALSE);

        [..]
    }
