    /// [`ResponseType::Cancel`][crate::ResponseType::Cancel] if he pressed cancel. It can also return

    ///
    /// ## Differences from [`FileChooserDialog`][crate::FileChooserDialog] ## {`gtkfilechooserdialognative`-differences}
    ///
    /// There are a few things in the GtkFileChooser API that are not
    /// possible to use with [`FileChooserNative`][crate::FileChooserNative], as such use would
    /// prohibit the use of a native dialog.
    ///
    /// There is no support for the signals that are emitted when the user
    /// navigates in the dialog, including:
    /// * `signal::FileChooser::current-folder-changed`
    /// * `signal::FileChooser::selection-changed`
    /// * `signal::FileChooser::file-activated`
    /// * `signal::FileChooser::confirm-overwrite`
    ///
    /// You can also not use the methods that directly control user navigation:
    /// * [`FileChooserExt::unselect_filename()`][crate::prelude::FileChooserExt::unselect_filename()]
    /// * [`FileChooserExt::select_all()`][crate::prelude::FileChooserExt::select_all()]
    /// * [`FileChooserExt::unselect_all()`][crate::prelude::FileChooserExt::unselect_all()]
    ///
    /// If you need any of the above you will have to use [`FileChooserDialog`][crate::FileChooserDialog] directly.
    ///
    /// No operations that change the the dialog work while the dialog is
    /// visible. Set all the properties that are required before showing the dialog.
    ///
    /// ## Win32 details ## {`gtkfilechooserdialognative`-win32}
    ///
    /// On windows the IFileDialog implementation (added in Windows Vista) is
    /// used. It supports many of the features that [`FileChooserDialog`][crate::FileChooserDialog]
    /// does, but there are some things it does not handle:
    ///
    /// * Extra widgets added with [`FileChooserExt::set_extra_widget()`][crate::prelude::FileChooserExt::set_extra_widget()].
    ///
    /// * Use of custom previews by connecting to `signal::FileChooser::update-preview`.
    ///
    /// * Any [`FileFilter`][crate::FileFilter] added using a mimetype or custom filter.
    ///
    /// If any of these features are used the regular [`FileChooserDialog`][crate::FileChooserDialog]
    /// will be used in place of the native one.
    ///
    /// ## Portal details ## {`gtkfilechooserdialognative`-portal}
    ///
    /// When the org.freedesktop.portal.FileChooser portal is available on the
    /// session bus, it is used to bring up an out-of-process file chooser. Depending
    /// on the kind of session the application is running in, this may or may not
    /// be a GTK+ file chooser. In this situation, the following things are not
    /// supported and will be silently ignored:
    ///
    /// * Extra widgets added with [`FileChooserExt::set_extra_widget()`][crate::prelude::FileChooserExt::set_extra_widget()].
    ///
    /// * Use of custom previews by connecting to `signal::FileChooser::update-preview`.
    ///
    /// * Any [`FileFilter`][crate::FileFilter] added with a custom filter.
    ///
    /// ## macOS details ## {`gtkfilechooserdialognative`-macos}
    ///
    /// On macOS the NSSavePanel and NSOpenPanel classes are used to provide native
    /// file chooser dialogs. Some features provided by [`FileChooserDialog`][crate::FileChooserDialog] are
    /// not supported:
    ///
    /// * Extra widgets added with [`FileChooserExt::set_extra_widget()`][crate::prelude::FileChooserExt::set_extra_widget()], unless the
    ///  widget is an instance of GtkLabel, in which case the label text will be used
    ///  to set the NSSavePanel message instance property.
    ///
    /// * Use of custom previews by connecting to `signal::FileChooser::update-preview`.
    ///
    /// * Any [`FileFilter`][crate::FileFilter] added with a custom filter.
    ///
    /// * Shortcut folders.
