TQLocalFs is not normally used directly, but rather through a TQUrlOperator, for example: \code TQUrlOperator op( "file:///tmp" ); op.listChildren(); // Asks the server to provide a directory listing \endcode This code will only work if the TQLocalFs class is registered; to register the class, you must call tqInitNetworkProtocols() before using a TQUrlOperator with TQLocalFs. If you really need to use TQLocalFs directly, don't forget to set its TQUrlOperator with setUrl(). \sa \link network.html TQt Network Documentation \endlink TQNetworkProtocol, TQUrlOperator */ /*!
