## Implemented Interfaces

GtkLinkButton implements AtkImplementorIface, GtkBuildable and GtkActivatable.

## Properties

      "visited"                  gboolean              : Read / Write

## Signals

## Description

A GtkLinkButton is a GtkButton 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_link_button_new()` or `gtk_link_button_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 `gtk_link_button_set_uri()`, and retrieved using `gtk_link_button_get_uri()`.

By default, GtkLinkButton 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.

## Details

### struct GtkLinkButton

    struct GtkLinkButton;

The GtkLinkButton structure contains only private data and should be accessed using the provided API.

### gtk_link_button_new ()

    GtkWidget *         gtk_link_button_new                 (const gchar *uri);

Creates a new GtkLinkButton with the URI as its text.

`uri` : | a valid URI
Returns : | a new link button widget.

Since 2.10

### gtk_link_button_new_with_label ()

    GtkWidget *         gtk_link_button_new_with_label      (const gchar *uri,
                                                             const gchar *label);

Creates a new GtkLinkButton containing a label.

`uri` : | a valid URI
`label` : | the text of the button. [allow-none]
Returns : | a new link button widget. [transfer none]

Since 2.10

### gtk_link_button_get_uri ()

    const gchar *       gtk_link_button_get_uri             (GtkLinkButton *link_button);

Retrieves the URI set using `gtk_link_button_set_uri()`.

`link_button` : | a GtkLinkButton
Returns : | a valid URI. The returned string is owned by the link button and should not be modified or freed.

Since 2.10

### gtk_link_button_set_uri ()

    void                gtk_link_button_set_uri             (GtkLinkButton *link_button,
                                                             const gchar *uri);

Sets `uri` as the URI where the GtkLinkButton points. As a side-effect this unsets the 'visited' state of the button.

`link_button` : | a GtkLinkButton
`uri` : | a valid URI

Since 2.10

### gtk_link_button_get_visited ()

    gboolean            gtk_link_button_get_visited         (GtkLinkButton *link_button);

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.

The state may also be changed using `gtk_link_button_set_visited()`.

`link_button` : | a GtkLinkButton
Returns : | `TRUE` if the link has been visited, `FALSE` otherwise

Since 2.14

### gtk_link_button_set_visited ()

    void                gtk_link_button_set_visited         (GtkLinkButton *link_button,
                                                             gboolean visited);

Sets the 'visited' state of the URI where the GtkLinkButton points. See `gtk_link_button_get_visited()` for more details.

`link_button` : | a GtkLinkButton
`visited` : | the new 'visited' state

Since 2.14

## Property Details

### The `"uri"` property

      "uri"                      gchar*                : Read / Write

The URI bound to this button.

Default value: NULL

Since 2.10

### The `"visited"` property

      "visited"                  gboolean              : Read / Write

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

Default value: FALSE

Since 2.14

## Signal Details

### The `"activate-link"` signal

    gboolean            user_function                      (GtkLinkButton *button,
                                                            gpointer       user_data)      : Run Last

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

The default handler will call `gtk_show_uri()` with the URI stored inside the "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.

`button` : | the GtkLinkButton that emitted the signal
`user_data` : | user data set when the signal handler was connected.
