Implemented Interfaces

GtkFileChooserDialog implements GtkAccessible, GtkBuildable, GtkConstraintTarget, GtkNative, GtkShortcutManager, GtkRoot and GtkFileChooser.


#include <gtk/gtk.h>


GtkFileChooserDialog is a dialog box suitable for use with “File Open” or “File Save” 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.

If you want to integrate well with the platform you should use the GtkFileChooserNative 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:

To use a dialog for saving, you can use this:

Setting up a file chooser dialog

There are various cases in which you may need to use a GtkFileChooserDialog:

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_file(), i.e. when you are doing a Save As command and you already have a file saved somewhere.

Response Codes

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:

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",

  gtk_widget_show (dialog);

  g_signal_connect (dialog, "response",
                    G_CALLBACK (on_open_response),

This will create buttons for “Cancel” and “Open” that use predefined 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:

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.


gtk_file_chooser_dialog_new ()

GtkWidget *
gtk_file_chooser_dialog_new (const char *title,
                             GtkWindow *parent,
                             GtkFileChooserAction action,
                             const char *first_button_text,

Creates a new GtkFileChooserDialog. This function is analogous to gtk_dialog_new_with_buttons().



Title of the dialog, or NULL.



Transient parent of the dialog, or NULL.



Open or save mode for the dialog


text to go in the first button, or NULL.



response ID for the first button, then additional (button, id) pairs, ending with NULL


a new GtkFileChooserDialog
