    ///
    /// The main area of a [`Dialog`][crate::Dialog] is called the "content area", and is yours
    /// to populate with widgets such a [`Label`][crate::Label] or [`Entry`][crate::Entry], to present
    /// your information, questions, or tasks to the user.
    ///
    /// In addition, dialogs allow you to add "action widgets". Most commonly,
    /// action widgets are buttons. Depending on the platform, action widgets may
    /// be presented in the header bar at the top of the window, or at the bottom
    /// of the window. To add action widgets, create your [`Dialog`][crate::Dialog] using
    /// [`with_buttons()`][Self::with_buttons()], or use
    /// [`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()].
    ///
    /// `GtkDialogs` uses some heuristics to decide whether to add a close
    /// button to the window decorations. If any of the action buttons use
    /// the response ID [`ResponseType::Close`][crate::ResponseType::Close] or [`ResponseType::Cancel`][crate::ResponseType::Cancel], the
    /// close button is omitted.
    ///
    /// Clicking a button that was added as an action widget will emit the
    /// `signal::Dialog::response` signal 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
    /// `signal::Dialog::response` signal will be emitted with the
    /// [`ResponseType::DeleteEvent`][crate::ResponseType::DeleteEvent] response ID.
    ///
    /// Dialogs are created with a call to [`new()`][Self::new()] or
    /// [`with_buttons()`][Self::with_buttons()]. The latter is recommended; it allows
    /// you to set the dialog title, some convenient flags, and add buttons.
    ///
    /// 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()]

    /// [`Dialog`][crate::Dialog] supports a custom `<action-widgets>` element, which can contain

    ///
    /// [`Dialog`][crate::Dialog] supports adding action widgets by specifying “action” as
    /// the “type” attribute of a `<child>` element. The widget will be added
