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.
| enum | Error { ErrConnectionRefused, ErrHostNotFound, ErrSocketRead } |
| typedef | State |
| void | setSocket ( int socket ) |
| int | socket () const |
| qulonglong | waitForMore ( int msecs, bool * timeout = 0 ) const |
| void | connectionClosed () |
| void | delayedCloseFinished () |
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. |
Use QAbstractSocket::SocketState instead.
| Qt 3 enum value | Qt 4 enum value |
|---|---|
| Idle | UnconnectedState |
| HostLookup | HostLookupState |
| Connecting | ConnectingState |
| Connected | ConnectedState |
| Closing | ClosingState |
| Connection | ConnectedState |
Use disconnected() instead.
Use disconnected() instead.
Use setSocketDescriptor() instead.
See also socket().
Use socketDescriptor() instead.
See also setSocket().
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.
