   5 // Creates a link button that shows |text| in blue and underlined. The cursor
   6 // changes to a hand when over the link.  This is like the GTK LinkButton, but
   7 // it doesn't call the global URI link handler, etc.  It is a button subclass,
   8 // so you can just handle the clicked signal.
