    /// Dialog boxes are a convenient way to prompt the user for a small amount
    /// of input, e.g. to display a message, ask a question, or anything else
    /// that does not require extensive effort on the user’s part.
    ///
    /// GTK+ treats a dialog as a window split vertically. The top section is a
    /// `GtkVBox`, and is where widgets such as a [`Label`][crate::Label] or a [`Entry`][crate::Entry] should
    /// be packed. The bottom area is known as the
    /// “action area”. This is generally used for
    /// packing buttons into the dialog which may perform functions such as
    /// cancel, ok, or apply.
    ///
    /// [`Dialog`][crate::Dialog] boxes are created with a call to [`new()`][Self::new()] or
    /// `gtk_dialog_new_with_buttons()`. `gtk_dialog_new_with_buttons()` is
    /// recommended; it allows you to set the dialog title, some convenient
    /// flags, and add simple buttons.
    ///
    /// If “dialog” is a newly created dialog, the two primary areas of the
    /// window can be accessed through [`DialogExt::content_area()`][crate::prelude::DialogExt::content_area()] and
    /// `gtk_dialog_get_action_area()`, as can be seen from the example below.
    ///
    /// A “modal” dialog (that is, one which freezes the rest of the application
    /// from user input), can be created by calling [`GtkWindowExt::set_modal()`][crate::prelude::GtkWindowExt::set_modal()] on the
    /// dialog. Use the GTK_WINDOW() macro to cast the widget returned from
    /// [`new()`][Self::new()] into a [`Window`][crate::Window]. When using `gtk_dialog_new_with_buttons()`
    /// you can also pass the [`DialogFlags::MODAL`][crate::DialogFlags::MODAL] flag to make a dialog modal.
    ///
    /// If you add buttons to [`Dialog`][crate::Dialog] using `gtk_dialog_new_with_buttons()`,
    /// [`DialogExt::add_button()`][crate::prelude::DialogExt::add_button()], [`DialogExtManual::add_buttons()`][crate::prelude::DialogExtManual::add_buttons()], or
    /// [`DialogExt::add_action_widget()`][crate::prelude::DialogExt::add_action_widget()], clicking the button will emit a signal
    /// called [`response`][struct@crate::Dialog#response] with a response ID that you specified. GTK+
    /// will never assign a meaning to positive response IDs; these are entirely
    /// user-defined. But for convenience, you can use the response IDs in the
    /// [`ResponseType`][crate::ResponseType] enumeration (these all have values less than zero). If
    /// a dialog receives a delete event, the [`response`][struct@crate::Dialog#response] signal will
    /// be emitted with a response ID of [`ResponseType::DeleteEvent`][crate::ResponseType::DeleteEvent].
    ///
    /// If you want to block waiting for a dialog to return before returning
    /// control flow to your code, you can call [`DialogExt::run()`][crate::prelude::DialogExt::run()]. This function
    /// enters a recursive main loop and waits for the user to respond to the
    /// dialog, returning the response ID corresponding to the button the user
    /// clicked.
    ///
    /// For the simple dialog in the following example, in reality you’d probably
    /// use [`MessageDialog`][crate::MessageDialog] to save yourself some effort. But you’d need to
    /// create the dialog contents manually if you had more than a simple message
    /// in the dialog.
    ///
    /// An example for simple GtkDialog usage:
    ///
    ///
    /// **⚠️ The following code is in C ⚠️**
    ///
    /// ```C
    /// // Function to open a dialog box with a message

    /// # GtkDialog as GtkBuildable
    ///
    /// The GtkDialog implementation of the [`Buildable`][crate::Buildable] interface exposes the
    /// `vbox` and `action_area` as internal children with the names “vbox” and
    /// “action_area”.
    ///
    /// GtkDialog supports a custom ``<action-widgets>`` element, which can contain
    /// multiple ``<action-widget>`` elements. The “response” attribute specifies a
    /// numeric response, and the content of the element is the id of widget
    /// (which should be a child of the dialogs `action_area`). To mark a response
    /// as default, set the “default“ attribute of the ``<action-widget>`` element
    /// to true.
    ///
    /// GtkDialog supports adding action widgets by specifying “action“ as
    /// the “type“ attribute of a ``<child>`` element. The widget will be added
    /// either to the action area or the headerbar of the dialog, depending
    /// on the “use-header-bar“ property. The response id has to be associated
    /// with the action widget using the ``<action-widgets>`` element.
    ///
    /// An example of a [`Dialog`][crate::Dialog] UI definition fragment:
    ///
    ///
    ///
    /// **⚠️ The following code is in xml ⚠️**
    ///
    /// ```xml
    /// <object class="GtkDialog" id="dialog1">
    ///   <child type="action">
    ///     <object class="GtkButton" id="button_cancel"/>
    ///   </child>
    ///   <child type="action">
