gtk tooltips and toolbutton

[Sandro Dentella]

Hi all,

    Why doesn't the tooltip show up in this toolbutton?
    Thanks in advance 

  import gtk

  w = gtk.Window()
  T = gtk.Toolbar()
  T.set_show_arrow(False)

  tb = gtk.ToolButton('gtk-refresh')

  tt = gtk.Tooltips()
  tt.set_tip(tb, "tooltip...")

  w.add(T)
  T.add(tb)
  w.show_all()
  gtk.main()
