enum QAbstractSocket::Error

Use QAbstractSocket::SocketError instead.

Member Function Documentation

void QAbstractSocket::connectionClosed ()   [signal]

Use closed() instead.

void QAbstractSocket::delayedCloseFinished ()   [signal]

Use closed() instead.

void QAbstractSocket::setSocket ( int socket )

Use setSocketDescriptor() instead.

See also socket().

int QAbstractSocket::socket () const

Use socketDescriptor() instead.

See also setSocket().

qulonglong QAbstractSocket::waitForMore ( int msecs, bool * timeout = 0 ) const

Use waitForReadyRead() instead.

For example, if you have code like

 bool timeout;
 Q_ULONG numBytes = socket->waitForMore(30000, &timeout);

you can rewrite it as

 qint64 numBytes = 0;
 if (socket->waitForReadyRead(msecs))
     numBytes = socket->bytesAvailable();
 bool timeout = (error() == QAbstractSocket::SocketTimeoutError);

See also waitForReadyRead(), bytesAvailable(), error(), and SocketTimeoutError.
