Class Details

class Gtk.LinkButton(*args, **kwargs)
Bases:Gtk.Button
Abstract:No
Structure:Gtk.LinkButtonClass

A Gtk.LinkButton is a Gtk.Button 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.LinkButton.new() or 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 Gtk.LinkButton can be set specifically using Gtk.LinkButton.set_uri(), and retrieved using Gtk.LinkButton.get_uri().

By default, Gtk.LinkButton calls Gtk.show_uri_on_window() when the button is clicked. This behaviour can be overridden by connecting to the Gtk.LinkButton ::activate-link signal and returning True from the signal handler.

CSS nodes

Gtk.LinkButton has a single CSS node with name button. To differentiate it from a plain Gtk.Button, it gets the .link style class.

classmethod new(uri)[source]
Parameters:uri (str) – a valid URI
Returns:a new link button widget.
Return type:Gtk.Widget

Creates a new Gtk.LinkButton with the URI as its text.

New in version 2.10.

classmethod new_with_label(uri, label)[source]
Parameters:
  • uri (str) – a valid URI
  • label (str or None) – the text of the button
Returns:

a new link button widget.

Return type:

Gtk.Widget

Creates a new Gtk.LinkButton containing a label.

New in version 2.10.

get_uri()[source]
Returns:a valid URI. The returned string is owned by the link button and should not be modified or freed.
Return type:str

Retrieves the URI set using Gtk.LinkButton.set_uri().

New in version 2.10.

get_visited()[source]
Returns:True if the link has been visited, False otherwise
Return type:bool

Retrieves the “visited” state of the URI where the Gtk.LinkButton points. The button becomes visited when it is clicked. If the URI is changed on the button, the “visited” state is unset again.

The state may also be changed using Gtk.LinkButton.set_visited().

New in version 2.14.

set_uri(uri)[source]
Parameters:uri (str) – a valid URI

Sets uri as the URI where the Gtk.LinkButton points. As a side-effect this unsets the “visited” state of the button.

New in version 2.10.

set_visited(visited)[source]
Parameters:visited (bool) – the new “visited” state

Sets the “visited” state of the URI where the Gtk.LinkButton points. See Gtk.LinkButton.get_visited() for more details.

New in version 2.14.

Return type:bool

Signal Details

Signal Name:activate-link
Flags:RUN_LAST
Parameters:link_button (Gtk.LinkButton) – The object which received the signal
Return type:bool

The ::activate-link signal is emitted each time the Gtk.LinkButton has been clicked.

The default handler will call Gtk.show_uri_on_window() with the URI stored inside the Gtk.LinkButton :uri property.

To override the default behavior, you can connect to the ::activate-link signal and stop the propagation of the signal by returning True from your handler.

Property Details

Gtk.LinkButton.props.uri
Name:uri
Type:str
Default Value:None
Flags:READABLE, WRITABLE

The URI bound to this button.

New in version 2.10.

Gtk.LinkButton.props.visited
Name:visited
Type:bool
Default Value:False
Flags:READABLE, WRITABLE, EXPLICIT_NOTIFY

The ‘visited’ state of this button. A visited link is drawn in a different color.

New in version 2.14.
