LinkButton

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.

Constructors

this this(GtkLinkButton* gtkLinkButton): Sets our main struct and passes it to the parent class

Functions

addOnActivateLink void addOnActivateLink(bool delegate(LinkButton) dlg, ConnectFlags connectFlags): 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. See Also GtkButton
getLinkButtonStruct GtkLinkButton* getLinkButtonStruct(): Undocumented in source. Be warned that the author may not have intended to support it.
getStruct void* getStruct(): the main Gtk struct as a void*
getUri string getUri(): Retrieves the URI set using gtk_link_button_set_uri(). Since 2.10
getVisited int getVisited(): 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
setStruct void setStruct(GObject* obj): Undocumented in source. Be warned that the author may not have intended to support it.
setUri void setUri(string 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
setVisited void setVisited(int visited): Sets the 'visited' state of the URI where the GtkLinkButton points. See gtk_link_button_get_visited() for more details. Since 2.14

addOnActivate void addOnActivate(void delegate(Button) dlg, ConnectFlags connectFlags): The ::activate signal on GtkButton is an action signal and emitting it causes the button to animate press then release. Applications should never connect to this signal, but use the "clicked" signal.

getAlignment void getAlignment(float xalign, float yalign): Gets the alignment of the child in the button. Since 2.4
setImage void setImage(Widget image): Set the image of button to the given widget. The image will be displayed if the label text is NULL or if "always-show-image" is TRUE. You don't have to call gtk_widget_show() on image yourself. Since 2.6
getImage Widget getImage(): Gets the widget that is currenty set as the image of button. This may have been explicitly set by gtk_button_set_image() or constructed by gtk_button_new_from_stock(). Since 2.6

getEventWindow Window getEventWindow(): Returns the button's event window if it is realized, NULL otherwise. This function should be rarely needed. Since 2.22
