## Properties

## 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()`.

GtkLinkButton offers a global hook, which is called when the used clicks on it: see `gtk_link_button_set_uri_hook()`.

GtkLinkButton was added in GTK+ 2.10.

## Details

### GtkLinkButton

    typedef struct _GtkLinkButton GtkLinkButton;

The GtkLinkButton struct contains private data only, and should be manipulated using the functions below.

### 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
Returns : | a new link button widget.

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.

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

Since 2.10

### GtkLinkButtonUriFunc ()

    void                (*GtkLinkButtonUriFunc)             (GtkLinkButton *button,
                                                             const gchar *link_,
                                                             gpointer user_data);

The type of a function which is called when the GtkLinkButton is clicked.

`button` : | the GtkLinkButton which was clicked
`link_` : |
`user_data` : | user data that was passed when the function was registered with `gtk_link_button_set_uri_hook()`

### gtk_link_button_set_uri_hook ()

    GtkLinkButtonUriFunc gtk_link_button_set_uri_hook       (GtkLinkButtonUriFunc func,
                                                             gpointer data,
                                                             GDestroyNotify destroy);

Sets `func` as the function that should be invoked every time a user clicks a GtkLinkButton. This function is called before every callback registered for the "clicked" signal.

`func` : | a function called each time a GtkLinkButton is clicked, or `NULL`
`data` : | user data to be passed to `func`, or `NULL`
`destroy` : | a GDestroyNotify that gets called when `data` is no longer needed, or `NULL`
Returns : | the previously set hook function.

Since 2.10

## Property Details
