  1. POudp packet is not received in QThread
    text
    copied!<p>I'm trying to receive some packets using a <code>udpReceiver</code> class that I have written using <code>qUdpSocket</code> in a separate <code>QThread</code> : </p> <pre><code>class udpThread : public QThread { private: QObject * parent; public: udpThread(QObject * parent = 0) { this-&gt;parent = parent; } void run() { UdpReceiver * test = new UdpReceiver(parent); } }; class UdpReceiver : public QObject { Q_OBJECT private: QUdpSocket * S; int port; public: UdpReceiver(QObject* parent = 0) : QObject(parent) { port = 9003; initialize(); } UdpReceiver(int p,QObject* parent = 0) : QObject(parent) { port = p; initialize(); } void initialize() { S = new QUdpSocket(); S-&gt;bind(port); S-&gt;connect(S,SIGNAL(readyRead()),this,SLOT(readPendingDiagrams())); qDebug() &lt;&lt; "Waiting for UDP data from port " &lt;&lt; port &lt;&lt; " ... \n"; } public slots: void readPendingDiagrams() { while(S-&gt;waitForReadyRead()) { QByteArray datagram; datagram.resize(S-&gt;pendingDatagramSize()); QHostAddress sender; quint16 senderPort; S-&gt;readDatagram(datagram.data(), datagram.size(),&amp;sender, &amp;senderPort); qDebug() &lt;&lt; datagram.size() &lt;&lt; " bytes received .... \n"; qDebug() &lt;&lt; " bytes received .... \n"; } } }; </code></pre> <p>And here is the <code>main()</code> method :</p> <pre><code>int main(int argc, char *argv[]) { QApplication a(argc, argv); // UdpReceiver * net = new UdpReceiver(); MainWindow w; udpThread * ut = new udpThread(); ut-&gt;start(); w.show(); return a.exec(); } </code></pre> <p>Now when I use the <code>udpReceiver</code> class to get the packets without the <code>QThread</code> it works just fine, but when I use the <code>udpThread</code> class it doesn't get the packets or at least the <code>raedyread()</code> signal does not activate some how. When I try to get the packets without the <code>QThread</code> my GUI crashes somehow and the whole program hangs, that's why I want to use <code>QThread</code>. I appreciate if you could help me solve this :) Regards,</p>
