GI.Gtk.Objects.FileChooserDialog

Description

FileChooserDialog is a dialog box suitable for use with “File/Open” or “File/Save as” 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:

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);

res = gtk_dialog_run (GTK_DIALOG (dialog));
if (res == GTK_RESPONSE_ACCEPT)
  {
    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 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” with fileChooserSetCurrentName.
  • To save a file under a different name. Use GTK_FILE_CHOOSER_ACTION_SAVE, and set the existing filename with fileChooserSetFilename.
  • 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 fileChooserSetFilename, 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 stock 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 [stock response code][gtkfilechooserdialog-responses] when you use FileChooserDialog to ensure proper operation.
