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.



Открытые типы

  • enum Error { ErrConnectionRefused, ErrHostNotFound, ErrSocketRead }
  • typedef State

Открытые функции

  • 22 открытых функций унаследованных от QIODevice
  • 8 открытых функций унаследованных от QObject

Сигналы


Описание типов членов

enum QAbstractSocket::Error

Use QAbstractSocket::SocketError instead.


Constant Value Description
QAbstractSocket::ErrConnectionRefused ConnectionRefusedError Use QAbstractSocket::ConnectionRefusedError instead.
QAbstractSocket::ErrHostNotFound HostNotFoundError Use QAbstractSocket::HostNotFoundError instead.
QAbstractSocket::ErrSocketRead UnknownSocketError Use QAbstractSocket::UnknownSocketError instead.

typedef QAbstractSocket::State

Use QAbstractSocket::SocketState instead.

Описание функций-членов

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.
