Description
FileChooserDialog is a dialog box suitable for use with
 “File Open” or “File Save” commands.  This widget works by
 putting a FileChooserWidget inside a Dialog.  It exposes
 the FileChooser interface, so you can use all of the
 FileChooser functions on the file chooser dialog as well as
 those for Dialog.
Note that FileChooserDialog does not have any methods of its
 own.  Instead, you should use the functions that work on a
 FileChooser.
If you want to integrate well with the platform you should use the
 FileChooserNative API, which will use a platform-specific
 dialog if available and fall back to GtkFileChooserDialog
 otherwise.
## Typical usage ## {gtkfilechooser-typical-usage}
In the simplest of cases, you can the following code to use
 FileChooserDialog to select a file for opening:
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_widget_show (dialog);
  g_signal_connect (dialog, "response",
                    G_CALLBACK (on_open_response),
                    NULL);To use a dialog for saving, you can use this:
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_widget_show (dialog);
  g_signal_connect (dialog, "response",
                    G_CALLBACK (on_save_response),
                    NULL);## Setting up a file chooser dialog ## {gtkfilechooserdialog-setting-up}
There are various cases in which you may need to use a FileChooserDialog:
- 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” withfileChooserSetCurrentName.
- To save a file under a different name. Use GTK_FILE_CHOOSER_ACTION_SAVE, and set the existing file withfileChooserSetFile.
- 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 fileChooserSetCurrentFolder 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 fileChooserSetFile,
 i.e. when you are doing a Save As command and you already
 have a file saved somewhere.
## Response Codes ## {gtkfilechooserdialog-responses}
FileChooserDialog inherits from 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 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 predefined
 response identifiers from ResponseType.  For most dialog
 boxes you can use your own custom response codes rather than the
 ones in ResponseType, but FileChooserDialog 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 FileChooserDialog 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][gtkfilechooserdialog-responses]
 when you use FileChooserDialog to ensure proper operation.
