[Glade-users] Help passing more than one variable as argument to a function

[Giovanni Corriga]

I haven't tried it, but I think you should use
gtk_signal_connect_object():

gtk_signal_connect_object(GTK_OBJECT(clean), "clicked", clear_entry,
GTK_OBJECT(entry1));
gtk_signal_connect_object(GTK_OBJECT(clean), "clicked", clear_entry,
GTK_OBJECT(entry2));
...

where clear_entry() is a function like

void clear_entry (GtkObject object)
{
  gtk_entry_set_text(GTK_ENTRY(entry), "");
}

In this way, you don't have to mess up interface.c.
