/**
 * A GtkLinkButton is a #GtkButton with a hyperlink, similar to the one
 * used by web browsers, which triggers an action when clicked. It is useful
 * to show quick links to resources.
 * 
 * A link button is created by calling either gtk_link_button_new() or
 * gtk_link_button_new_with_label(). If using the former, the URI you pass
 * to the constructor is used as a label for the widget.
 * 
 * The URI bound to a GtkLinkButton can be set specifically using
 * gtk_link_button_set_uri(), and retrieved using gtk_link_button_get_uri().
 * 
 * By default, GtkLinkButton calls gtk_show_uri() when the button is
 * clicked. This behaviour can be overridden by connecting to the
 * #GtkLinkButton::activate-link signal and returning %TRUE from the
 * signal handler.
 * 
 * # CSS nodes
 * 
 * GtkLinkButton has a single CSS node with name button. To differentiate
 * it from a plain #GtkButton, it gets the .link style class.
