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 #GtkLinkButton::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.

class LinkButton : Button {

protected

GtkLinkButton* gtkLinkButton;

GtkLinkButton* getLinkButtonStruct();

void* getStruct();

void setStruct(GObject* obj);

this(GtkLinkButton* gtkLinkButton, bool ownedRef);

Constructors

this this(GtkLinkButton* gtkLinkButton, bool ownedRef): Sets our main struct and passes it to the parent class.
this this(string uri): Creates a new #GtkLinkButton with the URI as its text.
this this(string uri, string label): Creates a new #GtkLinkButton containing a label.

Functions

addOnActivateLink gulong addOnActivateLink(bool delegate(LinkButton) dlg, ConnectFlags connectFlags): The ::activate-link signal is emitted each time the #GtkLinkButton has been clicked.
getLinkButtonStruct GtkLinkButton* getLinkButtonStruct(): Get the main Gtk struct
getStruct void* getStruct(): the main Gtk struct as a void*
getUri string getUri(): Retrieves the URI set using gtk_link_button_set_uri().
getVisited bool 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.
internalRemoveOnActivateLink void internalRemoveOnActivateLink(OnActivateLinkDelegateWrapper source): Undocumented in source. Be warned that the author may not have intended to support it.
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.
setVisited void setVisited(bool visited): Sets the “visited” state of the URI where the #GtkLinkButton points. See gtk_link_button_get_visited() for more details.

From Button

gtkButton GtkButton* gtkButton;: the main Gtk struct
getButtonStruct GtkButton* getButtonStruct(): Get the main Gtk struct

setIconSize void setIconSize(IconSize iconSize)
getIconSize IconSize getIconSize()
getType GType getType()
clicked void clicked(): Emits a #GtkButton::clicked signal to the given #GtkButton.
enter void enter(): Emits a #GtkButton::enter signal to the given #GtkButton.
getAlignment void getAlignment(float xalign, float yalign): Gets the alignment of the child in the button.
getAlwaysShowImage bool getAlwaysShowImage(): Returns whether the button will ignore the #GtkSettings:gtk-button-images setting and always show the image, if available.
getEventWindow Window getEventWindow(): Returns the button’s event window if it is realized, %NULL otherwise. This function should be rarely needed.
getFocusOnClick bool getFocusOnClick(): Returns whether the button grabs focus when it is clicked with the mouse. See gtk_button_set_focus_on_click().
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().
getImagePosition GtkPositionType getImagePosition(): Gets the position of the image relative to the text inside the button.
getLabel string getLabel(): Fetches the text from the label of the button, as set by gtk_button_set_label(). If the label text has not been set the return value will be %NULL. This will be the case if you create an empty button with gtk_button_new() to use as a container.
getRelief GtkReliefStyle getRelief(): Returns the current relief style of the given #GtkButton.
getUseStock bool getUseStock(): Returns whether the button label is a stock item.
getUseUnderline bool getUseUnderline(): Returns whether an embedded underline in the button label indicates a mnemonic. See gtk_button_set_use_underline ().
leave void leave(): Emits a #GtkButton::leave signal to the given #GtkButton.
pressed void pressed(): Emits a #GtkButton::pressed signal to the given #GtkButton.
released void released(): Emits a #GtkButton::released signal to the given #GtkButton.
setAlignment void setAlignment(float xalign, float yalign): Sets the alignment of the child. This property has no effect unless the child is a #GtkMisc or a #GtkAlignment.
setAlwaysShowImage void setAlwaysShowImage(bool alwaysShow): If %TRUE, the button will ignore the #GtkSettings:gtk-button-images setting and always show the image, if available.
setFocusOnClick void setFocusOnClick(bool focusOnClick): Sets whether the button will grab focus when it is clicked with the mouse. Making mouse clicks not grab focus is useful in places like toolbars where you don’t want the keyboard focus removed from the main area of the application.
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 #GtkButton:always-show-image is %TRUE. You don’t have to call gtk_widget_show() on @image yourself.
setImagePosition void setImagePosition(GtkPositionType position): Sets the position of the image relative to the text inside the button.
setLabel void setLabel(string label): Sets the text of the label of the button to @str. This text is also used to select the stock item if gtk_button_set_use_stock() is used.
setRelief void setRelief(GtkReliefStyle relief): Sets the relief style of the edges of the given #GtkButton widget. Two styles exist, %GTK_RELIEF_NORMAL and %GTK_RELIEF_NONE. The default style is, as one can guess, %GTK_RELIEF_NORMAL. The deprecated value %GTK_RELIEF_HALF behaves the same as %GTK_RELIEF_NORMAL.
setUseStock void setUseStock(bool useStock): If %TRUE, the label set on the button is used as a stock id to select the stock item for the button.
setUseUnderline void setUseUnderline(bool useUnderline): If true, an underline in the text of the button label indicates the next character should be used for the mnemonic accelerator key.
