Detailed Description

Create buttons bound to a URL.

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.

The URI bound to a Gtk::LinkButton can be set specifically using set_uri(), and retrieved using get_uri(). By default, Gtk::LinkButton calls gtk_show_uri() when the button is clicked. This behaviour can be overridden by connecting to the activate_link signal and returning true from the signal handler.

The LinkButton widget looks like this:

Since gtkmm 2.10:

Member Function Documentation

Glib::ustring Gtk::LinkButton::get_uri

(

)

const

Retrieves the URI set using set_uri().

Since gtkmm 2.10:

Returns:

A valid URI. The returned string is owned by the link button and should not be modified or freed.

bool Gtk::LinkButton::get_visited

(

)

const

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 set_visited().

Since gtkmm 2.14:

Returns:

true if the link has been visited, false otherwise.

GtkLinkButton* Gtk::LinkButton::gobj

(

)

[inline]

Provides access to the underlying C GtkObject.

Reimplemented from Gtk::Button.

const GtkLinkButton* Gtk::LinkButton::gobj

(

)

virtual bool Gtk::LinkButton::on_activate_link

(

)

[protected, virtual]

Glib::PropertyProxy<Glib::ustring> Gtk::LinkButton::property_uri

(

)

The URI bound to this button.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:

A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

Glib::PropertyProxy_ReadOnly<Glib::ustring> Gtk::LinkButton::property_uri

(

)

const

The URI bound to this button.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:

A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

Glib::PropertyProxy_ReadOnly<bool> Gtk::LinkButton::property_visited

(

)

const

Whether this link has been visited.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:

A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

Glib::PropertyProxy<bool> Gtk::LinkButton::property_visited

(

)

Whether this link has been visited.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:

A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

void Gtk::LinkButton::set_uri

(

const Glib::ustring &

uri

)

Sets uri as the URI where the Gtk::LinkButton points.

As a side-effect this unsets the 'visited' state of the button.

Since gtkmm 2.10:

Parameters:

uri	A valid URI.

void Gtk::LinkButton::set_visited

(

bool

visited = true

)

Sets the 'visited' state of the URI where the Gtk::LinkButton points.

See get_visited() for more details.

Since gtkmm 2.14:

Parameters:

visited

The new 'visited' state.

Glib::SignalProxy0< bool > Gtk::LinkButton::signal_activate_link

(

)

Prototype:

bool on_my_activate_link()

Friends And Related Function Documentation

Gtk::LinkButton* wrap	(	GtkLinkButton *	object,
		bool	take_copy = false
	)		[related]

A Glib::wrap() method for this object.

Parameters:

object	The C instance.
take_copy	False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns:

A C++ instance that wraps this C instance.
