    /// [`FileChooserNative`][crate::FileChooserNative] is an abstraction of a dialog suitable
    /// for use with “File Open” or “File Save as” commands.
    ///
    /// By default, this just uses a [`FileChooserDialog`][crate::FileChooserDialog] to implement
    /// the actual dialog. However, on some platforms, such as Windows and
    /// macOS, the native platform file chooser is used instead. When the
    /// application is running in a sandboxed environment without direct
    /// filesystem access (such as Flatpak), [`FileChooserNative`][crate::FileChooserNative] may call
    /// the proper APIs (portals) to let the user choose a file and make it
    /// available to the application.
    ///
    /// While the API of [`FileChooserNative`][crate::FileChooserNative] closely mirrors [`FileChooserDialog`][crate::FileChooserDialog],
    /// the main difference is that there is no access to any [`Window`][crate::Window] or [`Widget`][crate::Widget]
    /// for the dialog. This is required, as there may not be one in the case of a
    /// platform native dialog.
    ///
    /// Showing, hiding and running the dialog is handled by the
    /// [`NativeDialog`][crate::NativeDialog] functions.
    ///
    /// Note that unlike [`FileChooserDialog`][crate::FileChooserDialog], [`FileChooserNative`][crate::FileChooserNative] objects
    /// are not toplevel widgets, and GTK does not keep them alive. It is your
    /// responsibility to keep a reference until you are done with the
    /// object.
    ///
    /// ## Typical usage
    ///
    /// In the simplest of cases, you can the following code to use
    /// [`FileChooserNative`][crate::FileChooserNative] to select a file for opening:

    /// ## Response Codes
    ///
    /// [`FileChooserNative`][crate::FileChooserNative] inherits from [`NativeDialog`][crate::NativeDialog],
    /// which means it will return [`ResponseType::Accept`][crate::ResponseType::Accept] if the user accepted,
    /// and [`ResponseType::Cancel`][crate::ResponseType::Cancel] if he pressed cancel. It can also return
    /// [`ResponseType::DeleteEvent`][crate::ResponseType::DeleteEvent] if the window was unexpectedly closed.
    ///
    /// ## Differences from [`FileChooserDialog`][crate::FileChooserDialog]
    ///
    /// There are a few things in the [`FileChooser`][crate::FileChooser] interface that
    /// are not possible to use with [`FileChooserNative`][crate::FileChooserNative], as such use would
    /// prohibit the use of a native dialog.
    ///
    /// No operations that change the dialog work while the dialog is visible.
    /// Set all the properties that are required before showing the dialog.
    ///
    /// ## Win32 details
    ///
    /// On windows the `IFileDialog` implementation (added in Windows Vista) is
    /// used. It supports many of the features that [`FileChooser`][crate::FileChooser] has, but
    /// there are some things it does not handle:
    ///
    /// * Any [`FileFilter`][crate::FileFilter] added using a mimetype
    ///
    /// If any of these features are used the regular [`FileChooserDialog`][crate::FileChooserDialog]
    /// will be used in place of the native one.
    ///
    /// ## Portal details
    ///
    /// 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.
    ///
    /// ## macOS details
    ///
    /// On macOS the `NSSavePanel` and `NSOpenPanel` classes are used to provide
    /// native file chooser dialogs. Some features provided by [`FileChooser`][crate::FileChooser]
    /// are not supported:
    ///
    /// * Shortcut folders.
