    /// 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
    /// `VBox`, and is where widgets such as a `Label` or a `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` boxes are created with a call to `Dialog::new` or
    /// `Dialog::new_with_buttons`. `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::get_content_area` and
    /// `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` on the
    /// dialog. Use the GTK_WINDOW() macro to cast the widget returned from
    /// `Dialog::new` into a `Window`. When using `Dialog::new_with_buttons`
    /// you can also pass the `DialogFlags::Modal` flag to make a dialog modal.
    ///
    /// If you add buttons to `Dialog` using `Dialog::new_with_buttons`,
    /// `DialogExt::add_button`, `DialogExt::add_buttons`, or
    /// `DialogExt::add_action_widget`, clicking the button will emit a signal
    /// called `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` enumeration (these all have values less than zero). If
    /// a dialog receives a delete event, the `Dialog::response` signal will
    /// be emitted with a response ID of `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`. 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` 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 `Dialog` usage:
    ///
    /// ```C
    /// // Function to open a dialog box with a message
    /// void
    /// quick_message (GtkWindow *parent, gchar *message)
    /// {
    ///  GtkWidget *dialog, *label, *content_area;
    ///  GtkDialogFlags flags;
    ///
    ///  // Create the widgets
    ///  flags = GTK_DIALOG_DESTROY_WITH_PARENT;
    ///  dialog = gtk_dialog_new_with_buttons ("Message",
    ///                                        parent,
    ///                                        flags,
    ///                                        _("_OK"),
    ///                                        GTK_RESPONSE_NONE,
    ///                                        NULL);
    ///  content_area = gtk_dialog_get_content_area (GTK_DIALOG (dialog));
    ///  label = gtk_label_new (message);
    ///
    ///  // Ensure that the dialog box is destroyed when the user responds
    ///
    ///  g_signal_connect_swapped (dialog,
    ///                            "response",
    ///                            G_CALLBACK (gtk_widget_destroy),
    ///                            dialog);
    ///
    ///  // Add the label, and show everything we’ve added
    ///
    ///  gtk_container_add (GTK_CONTAINER (content_area), label);
    ///  gtk_widget_show_all (dialog);

    /// # `Dialog` as `Buildable`
    ///
    /// The `Dialog` implementation of the `Buildable` interface exposes the
    /// `vbox` and `action_area` as internal children with the names “vbox” and
    /// “action_area”.
    ///
    /// `Dialog` 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.
    ///
    /// `Dialog` 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` UI definition fragment:
    ///
    /// ```text
    /// <object class="GtkDialog" id="dialog1">
    ///   <child type="action">
    ///     <object class="GtkButton" id="button_cancel"/>
    ///   </child>
    ///   <child type="action">
    ///     <object class="GtkButton" id="button_ok">
    ///       <property name="can-default">True</property>
    ///     </object>
    ///   </child>
    ///   <action-widgets>
    ///     <action-widget response="cancel">button_cancel</action-widget>
    ///     <action-widget response="ok" default="true">button_ok</action-widget>
