Member Function Documentation

void QtNetwork.IQAbstractSocketSignals.Connected

(

)

This signal is emitted after connectToHost() has been called and a connection has been successfully established.

Note: On some operating systems the connected() signal may be directly emitted from the connectToHost() call for connections to the localhost.

See also connectToHost() and disconnected().

void QtNetwork.IQAbstractSocketSignals.ConnectionClosed

(

)

void QtNetwork.IQAbstractSocketSignals.DelayedCloseFinished

(

)

void QtNetwork.IQAbstractSocketSignals.Disconnected

(

)

This signal is emitted when the socket has been disconnected.

Warning: If you need to delete the sender() of this signal in a slot connected to it, use the deleteLater() function.

See also connectToHost(), disconnectFromHost(), and abort().

void QtNetwork.IQAbstractSocketSignals.Error

(

QAbstractSocket.SocketError

arg1

)

Returns the type of error that last occurred.

See also state() and errorString().

void QtNetwork.IQAbstractSocketSignals.HostFound

(

)

This signal is emitted after connectToHost() has been called and the host lookup has succeeded.

Note: Since Qt 4.6.3 QAbstractSocket may emit hostFound() directly from the connectToHost() call since a DNS result could have been cached.

See also connected().

void QtNetwork.IQAbstractSocketSignals.ProxyAuthenticationRequired	(	QNetworkProxy	proxy,
		QAuthenticator	authenticator
	)

This signal can be emitted when a proxy that requires authentication is used. The authenticator object can then be filled in with the required details to allow authentication and continue the connection.

Note: It is not possible to use a QueuedConnection to connect to this signal, as the connection will fail if the authenticator has not been filled in with new information when the signal returns.

This function was introduced in Qt 4.3.

See also QAuthenticator and QNetworkProxy.

void QtNetwork.IQAbstractSocketSignals.StateChanged

(

QAbstractSocket.SocketState

arg1

)

This signal is emitted whenever QAbstractSocket's state changes. The socketState parameter is the new state.

QAbstractSocket::SocketState is not a registered metatype, so for queued connections, you will have to register it with Q_REGISTER_METATYPE() and qRegisterMetaType().

See also state() and Creating Custom Qt Types.
