Qt 3 Support Members for QAbstractSocket

The following class members are part of the Qt 3 support layer. They are provided to help you port old code to Qt 4. We advise against using them in new code.

Public Types

enum Error { ErrConnectionRefused, ErrHostNotFound, ErrSocketRead }
typedef State

Public Functions

void setSocket ( int socket )
int socket () const
qulonglong waitForMore ( int msecs, bool * timeout = 0 ) const
  • 22 public functions inherited from QIODevice
  • 8 public functions inherited from QObject

Signals

void connectionClosed ()
void delayedCloseFinished ()

Member Type Documentation

enum QAbstractSocket::Error

Use QAbstractSocket::SocketError instead.

ConstantValueDescription
QAbstractSocket::ErrConnectionRefusedConnectionRefusedErrorUse QAbstractSocket::ConnectionRefusedError instead.
QAbstractSocket::ErrHostNotFoundHostNotFoundErrorUse QAbstractSocket::HostNotFoundError instead.
QAbstractSocket::ErrSocketReadUnknownSocketErrorUse QAbstractSocket::UnknownSocketError instead.

Member Function Documentation

void QAbstractSocket::connectionClosed () [signal]

Use disconnected() instead.

void QAbstractSocket::delayedCloseFinished () [signal]

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.
