/**
 * GtkFileChooserDialog:
 *
 * `GtkFileChooserDialog` is a dialog suitable for use with
 * “File Open” or “File Save” commands.
 *
 * ![An example GtkFileChooserDialog](filechooser.png)
 *
 * This widget works by putting a [class@Gtk.FileChooserWidget]
 * inside a [class@Gtk.Dialog]. It exposes the [iface@Gtk.FileChooser]
 * interface, so you can use all of the [iface@Gtk.FileChooser] functions
 * on the file chooser dialog as well as those for [class@Gtk.Dialog].
 *
 * Note that `GtkFileChooserDialog` does not have any methods of its
 * own. Instead, you should use the functions that work on a
 * [iface@Gtk.FileChooser].
 *
 * If you want to integrate well with the platform you should use the
 * [class@Gtk.FileChooserNative] API, which will use a platform-specific
 * dialog if available and fall back to `GtkFileChooserDialog`
 * otherwise.
 *
 * ## Typical usage
 *
 * In the simplest of cases, you can the following code to use
 * `GtkFileChooserDialog` to select a file for opening:
 *
 * ```c
 * static void
 * on_open_response (GtkDialog *dialog,
 *                   int        response)
 * {
 *   if (response == GTK_RESPONSE_ACCEPT)
 *     {
 *       GtkFileChooser *chooser = GTK_FILE_CHOOSER (dialog);
 *
 *       g_autoptr(GFile) file = gtk_file_chooser_get_file (chooser);
 *
 *       open_file (file);
 *     }
 *
 *   gtk_window_destroy (GTK_WINDOW (dialog));
 * }
 *
 *   // ...
 *   GtkWidget *dialog;
 *   GtkFileChooserAction action = GTK_FILE_CHOOSER_ACTION_OPEN;
 *
 *   dialog = gtk_file_chooser_dialog_new ("Open File",
 *                                         parent_window,
 *                                         action,
 *                                         _("_Cancel"),
 *                                         GTK_RESPONSE_CANCEL,
 *                                         _("_Open"),
 *                                         GTK_RESPONSE_ACCEPT,
 *                                         NULL);
 *
 *   gtk_window_present (GTK_WINDOW (dialog));
 *
 *   g_signal_connect (dialog, "response",
 *                     G_CALLBACK (on_open_response),
 *                     NULL);
 * ```
 *
 * To use a dialog for saving, you can use this:
 *
 * ```c
 * static void
 * on_save_response (GtkDialog *dialog,
 *                   int        response)
 * {
 *   if (response == GTK_RESPONSE_ACCEPT)
 *     {
 *       GtkFileChooser *chooser = GTK_FILE_CHOOSER (dialog);
 *
 *       g_autoptr(GFile) file = gtk_file_chooser_get_file (chooser);
 *
 *       save_to_file (file);
 *     }
 *
 *   gtk_window_destroy (GTK_WINDOW (dialog));
 * }
 *
 *   // ...
 *   GtkWidget *dialog;
 *   GtkFileChooser *chooser;
 *   GtkFileChooserAction action = GTK_FILE_CHOOSER_ACTION_SAVE;
 *
 *   dialog = gtk_file_chooser_dialog_new ("Save File",
 *                                         parent_window,
 *                                         action,
 *                                         _("_Cancel"),
 *                                         GTK_RESPONSE_CANCEL,
 *                                         _("_Save"),
 *                                         GTK_RESPONSE_ACCEPT,
 *                                         NULL);
 *   chooser = GTK_FILE_CHOOSER (dialog);
 *
 *   if (user_edited_a_new_document)
 *     gtk_file_chooser_set_current_name (chooser, _("Untitled document"));
 *   else
 *     gtk_file_chooser_set_file (chooser, existing_filename);
 *
 *   gtk_window_present (GTK_WINDOW (dialog));
 *
 *   g_signal_connect (dialog, "response",
 *                     G_CALLBACK (on_save_response),
 *                     NULL);
 * ```
 *
 * ## Setting up a file chooser dialog
 *
 * There are various cases in which you may need to use a `GtkFileChooserDialog`:
 *
 * - To select a file for opening, use %GTK_FILE_CHOOSER_ACTION_OPEN.
 *
 * - To save a file for the first time, use %GTK_FILE_CHOOSER_ACTION_SAVE,
 *   and suggest a name such as “Untitled” with
 *   [method@Gtk.FileChooser.set_current_name].
 *
 * - To save a file under a different name, use %GTK_FILE_CHOOSER_ACTION_SAVE,
 *   and set the existing file with [method@Gtk.FileChooser.set_file].
 *
 * - To choose a folder instead of a filem use %GTK_FILE_CHOOSER_ACTION_SELECT_FOLDER.
 *
 * In general, you should only cause the file chooser to show a specific
 * folder when it is appropriate to use [method@Gtk.FileChooser.set_file],
 * i.e. when you are doing a “Save As” command and you already have a file
 * saved somewhere.

 * ## Response Codes
 *
 * `GtkFileChooserDialog` inherits from [class@Gtk.Dialog], so buttons that
 * go in its action area have response codes such as %GTK_RESPONSE_ACCEPT and
 * %GTK_RESPONSE_CANCEL. For example, you could call
 * [ctor@Gtk.FileChooserDialog.new] as follows:
 *
 * ```c
 * GtkWidget *dialog;
 * GtkFileChooserAction action = GTK_FILE_CHOOSER_ACTION_OPEN;
 *
 * dialog = gtk_file_chooser_dialog_new ("Open File",
 *                                       parent_window,
 *                                       action,
 *                                       _("_Cancel"),
 *                                       GTK_RESPONSE_CANCEL,
 *                                       _("_Open"),
 *                                       GTK_RESPONSE_ACCEPT,
 *                                       NULL);
 * ```
 *
 * This will create buttons for “Cancel” and “Open” that use predefined
 * response identifiers from [enum@Gtk.ResponseType].  For most dialog
 * boxes you can use your own custom response codes rather than the
 * ones in [enum@Gtk.ResponseType], but `GtkFileChooserDialog` assumes that
 * its “accept”-type action, e.g. an “Open” or “Save” button,
 * will have one of the following response codes:
 *
 * - %GTK_RESPONSE_ACCEPT
 * - %GTK_RESPONSE_OK
 * - %GTK_RESPONSE_YES
 * - %GTK_RESPONSE_APPLY
 *
 * This is because `GtkFileChooserDialog` must intercept responses and switch
 * to folders if appropriate, rather than letting the dialog terminate — the
 * implementation uses these known response codes to know which responses can
 * be blocked if appropriate.
 *
 * To summarize, make sure you use a predefined response code
 * when you use `GtkFileChooserDialog` to ensure proper operation.
 *
 * Deprecated: 4.10: Use [class@Gtk.FileDialog] instead
