Struct FileChooserDialog

pub struct FileChooserDialog { /* private fields */ }

👎Deprecated: Since 4.10

Use FileDialog instead FileChooserDialog is a dialog 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 FileChooserDialog otherwise.

Typical usage

In the simplest of cases, you can the following code to use FileChooserDialog to select a file for opening:

⚠️ The following code is in 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:

⚠️ The following code is in 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 FileChooserDialog:

• To select a file for opening, use FileChooserAction::Open.

• To save a file for the first time, use FileChooserAction::Save, and suggest a name such as “Untitled” with FileChooserExt::set_current_name().

• To save a file under a different name, use FileChooserAction::Save, and set the existing file with FileChooserExt::set_file().

• To choose a folder instead of a filem use FileChooserAction::SelectFolder.

In general, you should only cause the file chooser to show a specific folder when it is appropriate to use FileChooserExt::set_file(), i.e. when you are doing a “Save As” command and you already have a file saved somewhere.

Response Codes

FileChooserDialog inherits from Dialog, so buttons that go in its action area have response codes such as ResponseType::Accept and ResponseType::Cancel. For example, you could call new() as follows:

⚠️ The following code is in 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 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:

• ResponseType::Accept
• ResponseType::Ok
• ResponseType::Yes
• ResponseType::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 when you use FileChooserDialog to ensure proper operation.
