LinkButton

open class LinkButton : Button, LinkButtonProtocol

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_on_window() 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.

The LinkButton type acts as a reference-counted owner of an underlying GtkLinkButton instance. It provides the methods that can operate on this data type through LinkButtonProtocol conformance. Use LinkButton as a strong reference or owner of a GtkLinkButton instance.

  • Designated initialiser from the underlying `C` data type.

    This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the LinkButton instance.

    Declaration

    Swift

    @inlinable
public init(_ op: UnsafeMutablePointer<GtkLinkButton>)

    Parameters

    op

    pointer to the underlying object
    Show on GitHub

  • Designated initialiser from a constant pointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the LinkButton instance.

    Declaration

    Swift

    @inlinable
public init(_ op: UnsafePointer<GtkLinkButton>)

    Parameters

    op

    pointer to the underlying object

  • Optional initialiser from a non-mutating gpointer to the underlying C data type. This creates an instance without performing an unbalanced retain i.e., ownership is transferred to the LinkButton instance.

    Declaration

    Swift

    @inlinable
override public init!(gpointer op: gpointer?)

    Parameters

    op

    gpointer to the underlying object

override public init!(gconstpointer op: gconstpointer?)

    Parameters

    op
