Member Type Documentation

enum QAbstractSocket::Error

Use QAbstractSocket::SocketError instead.

QAbstractSocket::ErrConnectionRefusedConnectionRefusedErrorUse QAbstractSocket::ConnectionRefusedError instead.
QAbstractSocket::ErrHostNotFoundHostNotFoundErrorUse QAbstractSocket::HostNotFoundError instead.

Member Function Documentation

[signal] void QAbstractSocket::connectionClosed()

Use disconnected() instead.

[signal] void QAbstractSocket::delayedCloseFinished()

Use disconnected() 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.
