/// A `GtkLinkButton` is a button with a hyperlink.
///
/// 
///
/// It is useful to show quick links to resources.
///
/// A link button is created by calling either [ctor@Gtk.LinkButton.new] or
/// [ctor@Gtk.LinkButton.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
/// [method@Gtk.LinkButton.set_uri].
///
/// By default, `GtkLinkButton` calls [method@Gtk.FileLauncher.launch] when the button
/// is clicked. This behaviour can be overridden by connecting to the
/// [signal@Gtk.LinkButton::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.
///
/// # Accessibility
///
/// `GtkLinkButton` uses the %GTK_ACCESSIBLE_ROLE_LINK role.
