The gtk.LinkButton
      is available in PyGTK 2.10 and above.
A gtk.LinkButton
    is a gtk.Button with
    a hyperlink, similar to the one used by web browsers, that triggers an
    action when clicked. It is useful to show quick links to
    resources.
A link button is created by calling the gtk.LinkButton constructor. The URI you pass to the constructor is used as a label for the widget.
The URI bound to a gtk.LinkButton
    can be set specifically using the set_uri())
    method, and retrieved using the get_uri()
    method.
gtk.LinkButton
    offers a global hook, which is called when the used clicks on it: see
    the gtk.link_button_set_uri_hook()
    function.
    gtk.LinkButton(uri, label=None)| 
 | a valid URI | 
| 
 | the text of the button or None | 
| Returns : | a new link button widget. | 
This constructor is available in PyGTK 2.10 and above.
Creates a new gtk.LinkButton
      with the URI specified by uri as its text if
      label is None. If
      label is not None, it is
      used as the text of the button.
    def get_uri()| Returns : | the associated URI. | 
This method is available in PyGTK 2.10 and above.
The get_uri() method returns the URI
      set using the gtk.LinkButton.set_uri()
      method or the gtk.LinkButton()
      constructor.
    def get_visited()| Returns : | Trueif the link has been visited,Falseotherwise | 
This method is available in PyGTK 2.14 and above.
	The get_visited() method retrieves the 'visited'
	state of the URI where the GtkLinkButton points. The button becomes visited
	when it is clicked. If the URI is changed on the button, the 'visited'
	state is unset again. 
      
    def set_uri(uri)| 
 | a valid URI | 
This method is available in PyGTK 2.10 and above.
The set_uri() method sets the string
      specified by uri as the URI the gtk.LinkButton
      points to.
    def set_visited(visited)| 
 | the new 'visited' state. | 
This method is available in PyGTK 2.14 and above.
	The set_visited() method setsthe 'visited' state
	of the URI where the
	gtk.LinkButton
	points. See
	gtk.LinkButton.get_visited()
	for more details.
      
    def gtk.link_button_set_uri_hook(func, data=None)| 
 | a function called each time a gtk.LinkButtonis clicked, orNone | 
| 
 | user data to be passed to func | 
This function is available in PyGTK 2.10 and above.
The gtk.link_button_set_uri_hook() function
      sets func as the function that should be
      invoked every time a user clicks a gtk.LinkButton.
      This function is called before every callback registered for the
      "clicked" signal. If func is
      None the current callback function will be
      removed.
