  38  * @Short_description: A file chooser dialog, suitable for "File/Open" or "File/Save" commands
  39  * @Title: GtkFileChooserDialog
  40  * @See_also: #GtkFileChooser, #GtkDialog
  41  *
  42  * #GtkFileChooserDialog is a dialog box suitable for use with
  43  * "File/Open" or "File/Save as" commands.  This widget works by
  44  * putting a #GtkFileChooserWidget inside a #GtkDialog.  It exposes
  45  * the #GtkFileChooserIface interface, so you can use all of the
  46  * #GtkFileChooser functions on the file chooser dialog as well as
  47  * those for #GtkDialog.
  48  *
  49  * Note that #GtkFileChooserDialog does not have any methods of its
  50  * own.  Instead, you should use the functions that work on a
  51  * #GtkFileChooser.
  52  *
  53  * <example id="gtkfilechooser-typical-usage">

 140  * when it is appropriate to use gtk_file_chooser_set_filename(),

 149  * #GtkFileChooserDialog inherits from #GtkDialog, so buttons that
 150  * go in its action area have response codes such as
 151  * #GTK_RESPONSE_ACCEPT and #GTK_RESPONSE_CANCEL.  For example, you
 152  * could call gtk_file_chooser_dialog_new() as follows:
 153  * <para>
 154  * <informalexample><programlisting>
 155  * GtkWidget *dialog;
 156  *
 157  * dialog = gtk_file_chooser_dialog_new ("Open File",

 163  * </programlisting></informalexample>
 164  * </para>
 165  * This will create buttons for "Cancel" and "Open" that use stock
 166  * response identifiers from #GtkResponseType.  For most dialog
 167  * boxes you can use your own custom response codes rather than the
 168  * ones in #GtkResponseType, but #GtkFileChooserDialog assumes that
 169  * its "accept"-type action, e.g. an "Open" or "Save" button,
 170  * <emphasis>will</emphasis> have one of the following response

 177  * <member>#GTK_RESPONSE_APPLY</member>
 178  * </simplelist>
 179  * </para>
 180  * This is because #GtkFileChooserDialog must intercept responses
 181  * and switch to folders if appropriate, rather than letting the
 182  * dialog terminate &mdash; the implementation uses these known
 183  * response codes to know which responses can be blocked if
