.SH DESCRIPTION
The QFtp class provides an implementation of the FTP protocol.
.PP
This class is derived from QNetworkProtocol. QFtp is not normally used directly, but rather through a QUrlOperator, for example:
.PP
.nf
.br
  QUrlOperator op( "ftp://ftp.trolltech.com" );
.br
  op.listChildren(); // Asks the server to provide a directory listing
.br
.fi
.PP
This code will only work if the QFtp class is registered; to register the class, you must call qInitNetworkProtocols() before using a QUrlOperator with QFtp.
.PP
If you really need to use QFtp directly, don't forget to set its QUrlOperator with setUrl().
.PP
See also Qt Network Documentation, QNetworkProtocol, QUrlOperator and Input/Output and Networking.
.SH MEMBER FUNCTION DOCUMENTATION
.SH "QFtp::QFtp ()"
Constructs a QFtp object.
.SH "QFtp::~QFtp ()\fC [virtual]\fR"
Destructor
.SH "void QFtp::dataBytesWritten ( int nbytes )\fC [protected slot]\fR"
This function is called, when \fInbytes\fR have been successfully written to the data socket.
.SH "void QFtp::dataClosed ()\fC [protected slot]\fR"
This function is called when the data connection has been closed.
.SH "void QFtp::dataConnected ()\fC [protected slot]\fR"
Some operations require a data connection to the server. If this connection could be opened, this function handles the data connection.
.SH "void QFtp::dataReadyRead ()\fC [protected slot]\fR"
This function is called when new data arrived on the data socket.
.SH "void QFtp::parseDir ( const QString & buffer, QUrlInfo & info )\fC [protected]\fR"
Parses the string, \fIbuffer\fR, which is one line of a directory listing which came from the FTP server, and sets the values which have been parsed to the url info object, \fIinfo\fR.
.SH "void QFtp::readyRead ()\fC [protected slot]\fR"
If data has arrived on the command socket, this slot is called. The
function loks at the data and passes it on to the function which can
handle it
