    /// The [`AboutDialog`][crate::AboutDialog] offers a simple way to display information about
    /// a program.
    ///
    /// The shown information includes the programs' 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.
    ///
    /// ![An example GtkAboutDialog](aboutdialog.png)
    ///
    /// 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 a [`AboutDialog`][crate::AboutDialog] 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.
    ///
    /// 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 [`AboutDialog`][crate::AboutDialog],
    /// as shown in the following example:
    ///
    /// **⚠️ The following code is in c ⚠️**
    ///
    /// ```c
    /// GFile *logo_file = g_file_new_for_path ("./logo.png");
    /// GdkTexture *example_logo = gdk_texture_new_from_file (logo_file, NULL);
