[Glade-users] Question???

I build a button in glade 3.4.0
    and set the 'Handler' of button to be 'on_button1_clicked'
    and set the 'User_data' to be 'Hello'.
when I use this function to get the value of the 'User_data'

void on_button1_clicked(GtkButton *button,gpointer user_data)
            g_print("User has clicked button1 %s\n",(gchar *)user_data);

I get this 'User has clicked button1 '.

It seems nothing to be returned.
