+ Most applications just need to turn on the <link
+ linkend="GtkFileChooser--do-overwrite-confirmation">do-overwrite-confirmation</link>
+ property (or call the

+ signal.
+ </para>
+
+ <para>
+ A signal handler for this signal must return a

+ should return #GTK_FILE_CHOOSER_CONFIRMATION_ACCEPT_FILENAME.
+ On the other hand, if it determines that the stock confirmation
