But it’s actually not that difficult to understand. In general Signals &amp; Slots are used to loosely connect classes. Illustrated by the keyword <code>emit</code>, Signals are used to broadcast a message to all connected Slots. If no Slots are connected, the message &ldquo;is lost in the wild&rdquo;. So a connection between Signals &amp; Slots is like a TCP/IP connection with a few exceptions, but this metaphor will help you to get the principle. A Signal is an outgoing port and a Slot is an input only port and a Signal can be connected to multiple Slots.</p>https://nidomiro.de/2016/12/how-to-start-with-qt/Fri, 07 Oct 2016 11:44:00 +0200https://nidomiro.de/2016/12/how-to-start-with-qt/<p>In this series I’ll give you a starting point on working with Qt. Like I mentioned in <em><a href="https://nidomiro.de/2016/10/en-why-i-love-the-qt-framework/">Why I love the Qt framework</a></em> I had a hard time at the beginning. I want to give you an easier start with this awesome peace of technology. This page will serve as an index for the whole series of tutorials and explanations. As more posts follow this page will be updated. I know there are plenty of tutorials on Qt, but maybe I’ll explain some things in a way you understand better.</p>
