Description

Create buttons bound to a URL

  • Module available since Gtk+ version 2.10

Synopsis

Detail

A LinkButton is a Button 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 linkButtonNew or linkButtonNewWithLabel. If using the former, the URI you pass to the constructor is used as a label for the widget.

The URI bound to a LinkButton can be set specifically using "set linkButton [linkButtonURI := uri]", and retrieved using "uri <- get linkButton linkButtonURI".

LinkButton offers a global hook, which is called when the used clicks on it: see linkButtonSetURIHook.

LinkButton was added in Gtk+ 2.10.

Methods

linkButtonSetUriHook :: (String -> IO ()) -> IO ()Source

Sets func as the function that should be invoked every time a user clicks a LinkButton. This function is called before every callback registered for the buttonClicked signal.

If no uri hook has been set, Gtk+ defaults to calling showURI.
