    <p>I'm sending two (or more) same signals, which receives one slot, but it is only called once instead of two times.. What I'm doing wrong?</p> <p>main.cpp:</p> <pre><code>#include &lt;QCoreApplication&gt; #include "app.h" int main(int argc, char *argv[]) { QCoreApplication a(argc, argv); App app; QMetaObject::invokeMethod(&amp;app, "run", Qt::QueuedConnection); return a.exec(); } </code></pre> <p>app.h:</p> <pre><code>#ifndef APP_H #define APP_H #include &lt;QObject&gt; #include "tcpserver.h" #include "tcpsocket.h" class App : public QObject { Q_OBJECT public: explicit App(QObject *parent = 0); signals: public slots: void run() { qDebug() &lt;&lt; "run()"; server.server_start(1111); socket.connectToHost("127.0.0.1", 1111); socket.write("hello", 5); socket.write("olleh", 5); // should execute slot two times. } private: TcpServer server; TcpSocket socket; }; #endif // APP_H </code></pre> <p>TcpSocket.h:</p> <pre><code>#ifndef TCPSOCKET_H #define TCPSOCKET_H #include &lt;QTcpSocket&gt; class TcpSocket : public QTcpSocket { Q_OBJECT public: explicit TcpSocket(QObject *parent = 0); signals: void dataReady(QByteArray data); public slots: void readyRead() { qDebug() &lt;&lt; "Bytes available:" &lt;&lt; this.bytesAvailable(); // called only once. data = this.readAll(); // just for testing. emit dataReady(data); // } void disconnected(); private: QByteArray data; }; #endif // TCPSOCKET_H </code></pre> <p>as you can see, I'm doing two socket.write functions, which should be handled two readyRead slots, but it is called only once. I honestly don't understand what I'm doing wrong.</p> <p>Regards.</p>

    2. COIt's not wise to define a slot in a derived class with the same name and signature of a signal in the parent class.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
