    /// The GtkAboutDialog offers a simple way to display information about
    /// a program like its logo, name, copyright, website and license. It is
    /// also possible to give credits to the authors, documenters, translators
    /// and artists who have worked on the program. An about dialog is typically
    /// opened when the user selects the `About` option from the `Help` menu.
    /// All parts of the dialog are optional.
    ///
    /// About dialogs often contain links and email addresses. GtkAboutDialog
    /// displays these as clickable links. By default, it calls [`show_uri_on_window()`][crate::show_uri_on_window()]
    /// when a user clicks one. The behaviour can be overridden with the
    /// `signal::AboutDialog::activate-link` signal.
    ///
    /// To specify a person with an email address, use a string like
    /// "Edgar Allan Poe <edgar\`poe`>". To specify a website with a title,
    /// use a string like "GTK+ team http://www.gtk.org".
    ///
    /// To make constructing a GtkAboutDialog as convenient as possible, you can
    /// use the function `gtk_show_about_dialog()` which constructs and shows a dialog
    /// and keeps it around so that it can be shown again.
    ///
    /// Note that GTK+ sets a default title of `_("About `s`")` on the dialog
    /// window (where \`s` is replaced by the name of the application, but in
    /// order to ensure proper translation of the title, applications should
    /// set the title property explicitly when constructing a GtkAboutDialog,
    /// as shown in the following example:
    ///
    ///
    /// **⚠️ The following code is in C ⚠️**
    ///
    /// ```C
    /// GdkPixbuf *example_logo = gdk_pixbuf_new_from_file ("./logo.png", NULL);
    /// gtk_show_about_dialog (NULL,
    ///                        "program-name", "ExampleCode",
    ///                        "logo", example_logo,
    ///                        "title", _("About ExampleCode"),
    ///                        NULL);
    /// ```
    ///
    /// It is also possible to show a [`AboutDialog`][crate::AboutDialog] like any other [`Dialog`][crate::Dialog],
    /// e.g. using [`DialogExt::run()`][crate::prelude::DialogExt::run()]. In this case, you might need to know that
