So this class lacks documentation until + I really know where all this will lead to. + + The plan however is to have a server that receives commands for selecting an + indenter and perhaps load some by the user predefined indenter config file. Then + the client can send a text to it and will receive it formatted. + The idea behind that is to make UiGUIs use as plugin or whatever more flexible. + So the plugin is developed for Eclipse for example and it takes the client role, + making it possible to use UiGUI from within Eclipse. Choosing a network protocol + makes everything platform and programming language independent, so it doesn't + matter for which application the plugin/client is developed. +*/ + +UiGuiIndentServer::UiGuiIndentServer(void) : + TQObject() +{ + _tcpServer = NULL; + _currentClientConnection = NULL; + _readyForHandleRequest = false; +} + +UiGuiIndentServer::~UiGuiIndentServer(void) +{ +} + +void UiGuiIndentServer::startServer() +{ + if (_tcpServer == NULL) + { + _tcpServer = new TQTcpServer(this); + } + + if (!_tcpServer->isListening()) + { + if (!_tcpServer->listen(TQHostAddress::Any, tquint16(84484))) + { + TQMessageBox::critical(NULL, tr("UiGUI Server"), + tr("Unable to start the server: %1.").arg(_tcpServer->errorString())); + return; + } + } + + connect(_tcpServer, SIGNAL(newConnection()), this, SLOT(handleNewConnection())); + _readyForHandleRequest = true; + _blockSize = 0; +} + +void UiGuiIndentServer::stopServer() +{ + if (_tcpServer != NULL) + { + _tcpServer->close(); + delete _tcpServer; + _tcpServer = NULL; + } + _currentClientConnection = NULL; + _readyForHandleRequest = false; +} + +void UiGuiIndentServer::handleNewConnection() +{ + TQTcpSocket *clientConnection = _tcpServer->nextPendingConnection(); + connect(clientConnection, SIGNAL(disconnected()), clientConnection, SLOT(deleteLater())); + + connect(clientConnection, SIGNAL(readyRead()), this, SLOT(handleReceivedData())); +} + +void UiGuiIndentServer::handleReceivedData() +{ + if (!_readyForHandleRequest) + { + return; + } + + _currentClientConnection = qobject_cast<TQTcpSocket*>(sender()); + TQString receivedData = ""; + + if (_currentClientConnection != NULL) + { + TQDataStream in(_currentClientConnection); + in.setVersion(TQDataStream::TQt_4_0); + + if (_blockSize == 0) + { + if (_currentClientConnection->bytesAvailable() < (int)sizeof(tquint32)) + { + return; + } + + in >> _blockSize; + } + + if (_currentClientConnection->bytesAvailable() < _blockSize) + { + return; + } + + TQString receivedMessage; + in >> receivedMessage; + + _blockSize = 0; + + tqDebug() << "receivedMessage: " << receivedMessage; + + if (receivedMessage == "ts") + { + sendMessage("Toll"); + } + else + { + sendMessage("irgendwas"); + } + } +} + +void UiGuiIndentServer::sendMessage(const TQString &message) +{ + _readyForHandleRequest = false; + + _dataToSend = ""; + TQDataStream out(&_dataToSend, TQIODevice::WriteOnly); + out.setVersion(TQDataStream::TQt_4_0); + out << (tquint32)0; + out << message; + out.device()->seek(0); + out << (tquint32)(_dataToSend.size() - sizeof(tquint32)); + + connect(_currentClientConnection, SIGNAL(bytesWritten(qint64)), this, + SLOT(checkIfReadyForHandleRequest())); + _currentClientConnection->write(_dataToSend); +} + +void UiGuiIndentServer::checkIfReadyForHandleRequest() +{ + if (_currentClientConnection->bytesToWrite() == 0) + { + TQString dataToSendStr = _dataToSend.right(_dataToSend.size() - sizeof(tquint32)); + tqDebug() << "checkIfReadyForHandleRequest _dataToSend was: " << dataToSendStr; + disconnect(_currentClientConnection, SIGNAL(bytesWritten(qint64)), this, + SLOT(checkIfReadyForHandleRequest())); + _readyForHandleRequest = true; + } +} |
