C++ (Cpp) dataReadyRead Examples

Example #1

File: sdrdaemonfecudphandler.cpp Project: f4exb/sdrangel

void SDRdaemonFECUDPHandler::start()
{
	qDebug("SDRdaemonFECUDPHandler::start");

	if (!m_dataSocket)
	{
		m_dataSocket = new QUdpSocket(this);
	}

	if (!m_dataConnected)
	{
		if (m_dataSocket->bind(m_dataAddress, m_dataPort))
		{
			qDebug("SDRdaemonFECUDPHandler::start: bind data socket to %s:%d", m_dataAddress.toString().toStdString().c_str(),  m_dataPort);
			connect(m_dataSocket, SIGNAL(readyRead()), this, SLOT(dataReadyRead()), Qt::QueuedConnection); // , Qt::QueuedConnection
			m_dataConnected = true;
		}
		else
		{
			qWarning("SDRdaemonFECUDPHandler::start: cannot bind data port %d", m_dataPort);
			m_dataConnected = false;
		}
	}

	// Need to notify the DSP engine to actually start
	DSPSignalNotification *notif = new DSPSignalNotification(m_samplerate, m_centerFrequency * 1000); // Frequency in Hz for the DSP engine
	m_deviceAPI->getDeviceInputMessageQueue()->push(notif);
    m_elapsedTimer.start();
}

Example #2

File: mainwindow.cpp Project: f4deb/Raspberry-Pi

void MainWindow::status_connecte(char *toto){
    statusBar()->showMessage(tr(toto));
    if (etat_serveur_port){
        serveurConnect->setText("Connected");
        serialGroupBox->setTitle("Port série distant");
        QObject::connect(servv, SIGNAL(dataReadyRead()), servv, SLOT(donneesRecues()));
        QObject::connect(servv, SIGNAL(dataServerReceived()), this, SLOT(readData()));
        }
    else{
        serveurConnect->setText("Disconnected");
        serialGroupBox->setTitle("Port série local");
    }
}

Example #3
