 * SECTION:gtkfilechooserdialog
 | 
						||
 * @Short_description: A file chooser dialog, suitable for “File/Open” or “File/Save” commands
 | 
						||
 * @Title: GtkFileChooserDialog
 | 
						||
 * @See_also: #GtkFileChooser, #GtkDialog
 | 
						||
 *
 | 
						||
 * #GtkFileChooserDialog is a dialog box suitable for use with
 | 
						||
 * “File/Open” or “File/Save as” commands.  This widget works by
 | 
						||
 * putting a #GtkFileChooserWidget inside a #GtkDialog.  It exposes
 | 
						||
 * the #GtkFileChooser interface, so you can use all of the
 | 
						||
 * #GtkFileChooser functions on the file chooser dialog as well as
 | 
						||
 * those for #GtkDialog.
 | 
						||
 *
 | 
						||
 * Note that #GtkFileChooserDialog does not have any methods of its
 | 
						||
 * own.  Instead, you should use the functions that work on a
 | 
						||
 * #GtkFileChooser.
 | 
						||
 *
 | 
						||
 * ## Typical usage ## {#gtkfilechooser-typical-usage}
 | 
						||
 *
 | 
						||
 * In the simplest of cases, you can the following code to use
 | 
						||
 * #GtkFileChooserDialog to select a file for opening:
 | 
						||
 *
 | 
						||
 * |[
 | 
						||
 * GtkWidget *dialog;
 | 
						||
 * GtkFileChooserAction action = GTK_FILE_CHOOSER_ACTION_OPEN;
 | 
						||
 * gint res;
 | 
						||
 *
 | 
						||
 * dialog = gtk_file_chooser_dialog_new ("Open File",
 | 
						||
 *                                       parent_window,
 | 
						||
 *                                       action,
 | 
						||
 *                                       _("_Cancel"),
 | 
						||
 *                                       GTK_RESPONSE_CANCEL,
 | 
						||
 *                                       _("_Open"),
 | 
						||
 *                                       GTK_RESPONSE_ACCEPT,
 | 
						||
 *                                       NULL);
 | 
						||
 *
 | 
						||
 * res = gtk_dialog_run (GTK_DIALOG (dialog));
 | 
						||
 * if (res == GTK_RESPONSE_ACCEPT)
 | 
						||
 *   {
 | 
						||
 *     char *filename;
 | 
						||
 *     GtkFileChooser *chooser = GTK_FILE_CHOOSER (dialog);
 | 
						||
 *     filename = gtk_file_chooser_get_filename (chooser);
 | 
						||
 *     open_file (filename);
 | 
						||
 *     g_free (filename);
 | 
						||
 *   }
 | 
						||
 *
 | 
						||
 * gtk_widget_destroy (dialog);
 | 
						||
 * ]|
 | 
						||
 *
 | 
						||
 * To use a dialog for saving, you can use this:
 | 
						||
 *
 | 
						||
 * |[
 | 
						||
 * GtkWidget *dialog;
 | 
						||
 * GtkFileChooser *chooser;
 | 
						||
 * GtkFileChooserAction action = GTK_FILE_CHOOSER_ACTION_SAVE;
 | 
						||
 * gint res;
 | 
						||
 *
 | 
						||
 * 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);
 | 
						||
 *
 | 
						||
 * 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);

						||
 *   {
 | 
						||
 *     char *filename;
 | 
						||
 *
 | 
						||
 *     filename = gtk_file_chooser_get_filename (chooser);
 | 
						||
 *     save_to_file (filename);
 | 
						||
 *     g_free (filename);
 | 
						||
 *   }
 | 
						||
 *
 | 
						||
 * gtk_widget_destroy (dialog);
 | 
						||
 * ]|
 | 
						||
 *
 | 
						||
 * ## Setting up a file chooser dialog ## {#gtkfilechooserdialog-setting-up}
 | 
						||
 *
 | 
						||
 * 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 gtk_file_chooser_set_current_name().
 | 
						||
 *
 | 
						||
 * - To save a file under a different name. Use #GTK_FILE_CHOOSER_ACTION_SAVE,
 | 
						||
 *   and set the existing filename with gtk_file_chooser_set_filename().
 | 
						||
 *
 | 
						||
 * - To choose a folder instead of a file. Use #GTK_FILE_CHOOSER_ACTION_SELECT_FOLDER.
 | 
						||
 *
 | 
						||
 * Note that old versions of the file chooser’s documentation suggested
 | 
						||
 * using gtk_file_chooser_set_current_folder() in various
 | 
						||
 * situations, with the intention of letting the application
 | 
						||
 * suggest a reasonable default folder.  This is no longer
 | 
						||
 * considered to be a good policy, as now the file chooser is
 | 
						||
 * able to make good suggestions on its own.  In general, you
 | 
						||
 * should only cause the file chooser to show a specific folder
 | 
						||
 * when it is appropriate to use gtk_file_chooser_set_filename(),
 | 
						||
 * i.e. when you are doing a Save As command and you already
 | 
						||
 * have a file saved somewhere.
 | 
						||
 | 
						||
 * ## Response Codes ## {#gtkfilechooserdialog-responses}
 | 
						||
 *
 | 
						||
 * #GtkFileChooserDialog inherits from #GtkDialog, 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 gtk_file_chooser_dialog_new() as follows:
 | 
						||
 *
 | 
						||
 * |[
 | 
						||
 * 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 stock
 | 
						||
 * response identifiers from #GtkResponseType.  For most dialog
 | 
						||
 * boxes you can use your own custom response codes rather than the
 | 
						||
 * ones in #GtkResponseType, 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
 | 
						||
 * [stock response code][gtkfilechooserdialog-responses]
 | 
						||
 * when you use #GtkFileChooserDialog to ensure proper operation.
