Implemented Interfaces

GtkFileChooserDialog implements AtkImplementorIface and GtkFileChooser.

Description

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 GtkFileChooserIface 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.

Example 6. Typical usage

In the simplest of cases, you can use GtkFileChooserDialog as in the following code:

GtkWidget *dialog;

dialog = gtk_file_chooser_dialog_new ("Open File",
				      parent_window,
				      GTK_FILE_CHOOSER_ACTION_OPEN,
				      GTK_STOCK_CANCEL, GTK_RESPONSE_CANCEL,
				      GTK_STOCK_OPEN, GTK_RESPONSE_ACCEPT,
				      NULL);

if (gtk_dialog_run (GTK_DIALOG (dialog)) == GTK_RESPONSE_ACCEPT)
  {
    char *filename;

    filename = gtk_file_chooser_get_filename (GTK_FILE_CHOOSER (dialog));
    open_file (filename);
    g_free (filename);
  }

gtk_widget_destroy (dialog);

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:

GtkWidget *dialog;

dialog = gtk_file_chooser_dialog_new ("Open File",
				      parent_window,
				      GTK_FILE_CHOOSER_ACTION_OPEN,
				      GTK_STOCK_CANCEL, GTK_RESPONSE_CANCEL,
				      GTK_STOCK_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.

Note

To summarize, make sure you use a stock response code when you use GtkFileChooserDialog to ensure proper operation.
