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::FileLauncher::launch() 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:

Member Function Documentation

get_type()

static GType Gtk::LinkButton::get_type ( )

static

Get the GType for this class, for use with the underlying GObject type system.

get_uri()

Glib::ustring Gtk::LinkButton::get_uri

(

)

const

Retrieves the URI of the Gtk::LinkButton.

Returns

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

get_visited()

bool Gtk::LinkButton::get_visited

(

)

const

Retrieves the “visited” state of the Gtk::LinkButton.

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().

Returns

true if the link has been visited, false otherwise.

gobj() [1/2]

GtkLinkButton * Gtk::LinkButton::gobj ( )

inline

Provides access to the underlying C GObject.

gobj() [2/2]

const GtkLinkButton * Gtk::LinkButton::gobj ( ) const

inline

Provides access to the underlying C GObject.

operator=() [1/2]

LinkButton & Gtk::LinkButton::operator= ( const LinkButton &  )

delete

operator=() [2/2]

LinkButton & Gtk::LinkButton::operator= ( LinkButton &&  src )

noexcept

property_uri() [1/2]

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

(

)

The URI bound to this button.

Default value: ""

Returns

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

property_uri() [2/2]

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

(

)

const

The URI bound to this button.

Default value: ""

Returns

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

property_visited() [1/2]

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

(

)

The 'visited' state of this button.

A visited link is drawn in a different color.

Default value: false

Returns

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

property_visited() [2/2]

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

(

)

const

The 'visited' state of this button.

A visited link is drawn in a different color.

Default value: false

Returns

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

set_uri()

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.

Parameters

uri	A valid URI.

set_visited()

void Gtk::LinkButton::set_visited

(

bool

visited = true

)

Sets the “visited” state of the Gtk::LinkButton.

See get_visited() for more details.

Parameters

visited

The new “visited” state.

signal_activate_link()

Glib::SignalProxy< bool()> Gtk::LinkButton::signal_activate_link

(

)

Slot Prototype:

bool on_my_activate_link()

Flags: Run Last

Emitted each time the Gtk::LinkButton is clicked.

The default handler will call Gtk::FileLauncher::launch() with the URI stored inside the property_uri() property.

To override the default behavior, you can connect to the signal_activate_link() signal and stop the propagation of the signal by returning true from your handler.

Returns

true if the signal has been handled.

wrap()

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.
