    /// About dialogs often contain links and email addresses. [`AboutDialog`][crate::AboutDialog]
    /// displays these as clickable links. By default, it calls [`FileLauncher::launch()`][crate::FileLauncher::launch()]
    /// when a user clicks one. The behaviour can be overridden with the
    /// [`activate-link`][struct@crate::AboutDialog#activate-link] signal.
    ///
    /// To specify a person with an email address, use a string like
    /// `Edgar Allan Poe <edgar@poe.com>`. To specify a website with a title,
    /// use a string like `GTK team https://www.gtk.org`.
    ///
    /// To make constructing an about dialog as convenient as possible, you can
    /// use the function [`show_about_dialog()`][crate::show_about_dialog()] which constructs and shows
    /// a dialog and keeps it around so that it can be shown again.
