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.

• QAbstractSocket class reference

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.

typedef QAbstractSocket::State

Use QAbstractSocket::SocketState 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.
