as a fallback, but also has support for the win32 file chooser dialog.

+ * SECTION:gtkfilechoosernative
+ * @Short_description: A native file chooser dialog, suitable for “File/Open” or “File/Save” commands
+ * @Title: GtkFileChooserNative
+ * @See_also: #GtkFileChooser, #GtkNativeDialog, #GtkFileChooserDialog
+ *
+ * #GtkFileChooserNative is an abstraction of a dialog box suitable
+ * for use with “File/Open” or “File/Save as” commands. By default, this
+ * just uses a #GtkFileChooserDialog to implement the actual dialog.
+ * However, on certain platforms, such as Windows, the native platform
+ * file chooser is uses instead.
+ *
+ * While the API of #GtkFileChooserNative closely mirrors #GtkFileChooserDialog, the main
+ * difference is that there is no access to any #GtkWindow or #GtkWidget 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 #GtkNativeDialog functions.
+ *
+ * ## Typical usage ## {#gtkfilechoosernative-typical-usage}
+ *
+ * In the simplest of cases, you can the following code to use
+ * #GtkFileChooserDialog to select a file for opening:
+ *
+ * |[
+ * GtkFileChooserNative *native;
+ * GtkFileChooserAction action = GTK_FILE_CHOOSER_ACTION_OPEN;
+ * gint res;
+ *
+ * native = gtk_file_chooser_native_new ("Open File",
+ * parent_window,
+ * action,
+ * "_Open",
+ * "_Cancel");
+ *
+ * res = gtk_native_dialog_run (GTK_NATIVE_DIALOG (native));
+ * if (res == GTK_RESPONSE_ACCEPT)
+ * {
+ * char *filename;
+ * GtkFileChooser *chooser = GTK_FILE_CHOOSER (native);
+ * filename = gtk_file_chooser_get_filename (chooser);
+ * open_file (filename);
+ * g_free (filename);
+ * }
+ *
+ * g_object_unref (native);
+ * ]|
+ *
+ * To use a dialog for saving, you can use this:
+ *
+ * |[
+ * GtkFileChooserNative *native;
+ * GtkFileChooser *chooser;
+ * GtkFileChooserAction action = GTK_FILE_CHOOSER_ACTION_SAVE;
+ * gint res;
+ *
+ * native = gtk_file_chooser_native_new ("Save File",
+ * parent_window,
+ * action,
+ * "_Save",
+ * "_Cancel");
+ * chooser = GTK_FILE_CHOOSER (native);
+ *
+ * gtk_file_chooser_set_do_overwrite_confirmation (chooser, TRUE);
+ *
+ * if (user_edited_a_new_document)
+ * gtk_file_chooser_set_current_name (chooser,
+ * _("Untitled document"));
+ * else
+ * gtk_file_chooser_set_filename (chooser,
+ * existing_filename);
+ *
+ * res = gtk_native_dialog_run (GTK_NATIVE_DIALOG (native));
+ * if (res == GTK_RESPONSE_ACCEPT)
+ * {
+ * char *filename;
+ *
+ * filename = gtk_file_chooser_get_filename (chooser);
+ * save_to_file (filename);
+ * g_free (filename);
+ * }
+ *
+ * g_object_unref (native);
+ * ]|
+ *
+ * For more information on how to best set up a file dialog, see #GtkFileChooserDialog.
+ *
+ * ## Response Codes ## {#gtkfilechooserdialognative-responses}
+ *
+ * #GtkFileChooserNative inherits from #GtkNativeDialog, which means it
+ * will return #GTK_RESPONSE_ACCEPT if the user accepted, and
+ * #GTK_RESPONSE_CANCEL if he pressed cancel. It can also return
+ * #GTK_RESPONSE_DELETE_EVENT if the window was unexpectedly closed.
+ *
+ * ## Differences from #GtkFileChooserDialog ## {#gtkfilechooserdialognative-differences}
+ *
+ * There are a few things in the GtkFileChooser API that are not
+ * possible to use with #GtkFileChooserNative, 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:
+ * * #GtkFileChooser::current-folder-changed
+ * * #GtkFileChooser::selection-changed
+ * * #GtkFileChooser::file-activated
+ * * #GtkFileChooser::confirm-overwrite
+ *
+ * You can also not use the methods that directly control user navigation:
+ * * gtk_file_chooser_unselect_filename()
+ * * gtk_file_chooser_select_all()
+ * * gtk_file_chooser_unselect_all()
+ *
+ * If you need any of the above you will have to use #GtkFileChooserDialog 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 #GtkFileChooserDialog
+ * does, but there are some things it does not handle:
+ *
+ * * Extra widgets added with gtk_file_chooser_set_extra_widget().
+ *
+ * * Use of custom previews by connecting to #GtkFileChooser::update-preview.
+ *
+ * * Any #GtkFileFilter added using a mimetype or custom filter.
+ *
+ * If any of these features are used the regular #GtkFileChooserDialog
+ * will be used in place of the native one.
