Qt piping data between plugins
<p>I'm developing an app based on plugins, following the <a href="http://doc.qt.io/qt-5/qtwidgets-tools-echoplugin-example.html" rel="nofollow">Echo Plugin Example</a>. </p>

<p>So far so good. Now I'm at a point where I would like to pipe data between plugins. I have one plugin which establishes a network connection using <code>QTcpSocket</code> and I have another plugin in which I would like to display the data in a <code>QTextEdit</code>. How do I pipe the data between plugins?</p>

<p>If both where simple objects I will do simple signal slot connection, but since the interface of plugins doesn't derive from QObject it's not possible to have signal slots. Or, at least I don't know how.</p>
