Implemented Interfaces
GtkLinkButton implements AtkImplementorIface, GtkBuildable, GtkActionable and GtkActivatable.
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.
CSS nodes
GtkLinkButton has a single CSS node with name button. To differentiate it from a plain GtkButton, it gets the .link style class.
Functions
gtk_link_button_new ()
GtkWidget *
gtk_link_button_new (const gchar *uri);
Creates a new GtkLinkButton with the URI as its text.
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.
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().
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.
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().
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.
Since: 2.14
Types and Values
struct GtkLinkButton
struct GtkLinkButton;
The GtkLinkButton contains only private data and should be accessed using the provided API.
struct GtkLinkButtonClass
struct GtkLinkButtonClass {
gboolean (* activate_link) (GtkLinkButton *button);
};
The GtkLinkButtonClass contains only private data.
Property Details
The “uri” property
“uri” gchar *
The URI bound to this button.
Flags: Read / Write
Default value: NULL
Since: 2.10
The “visited” property
“visited” gboolean
The 'visited' state of this button. A visited link is drawn in a different color.
Flags: Read / Write
Default value: FALSE
Since: 2.14
Signal Details
The “activate-link” signal
gboolean user_function (GtkLinkButton *button, gpointer user_data)
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.
Parameters
button |
the GtkLinkButton that emitted the signal |
|
user_data |
user data set when the signal handler was connected. |
Flags: Run Last
