Writing a basic Qt project with Qt Creator

I’m assuming you are already able to program and at least had a look at C++. For example I won’t explain why int main(int argc, char *argv[]) is in the C++ source code.

If you create a "Qt Console Application" you will have the following code:

Qt Signals & Slots: How they work

Wed, 07 Dec 2016 11:44:10 +0200

The one thing that confuses the most people in the beginning is the Signal & Slot mechanism of Qt. But it’s actually not that difficult to understand. In general Signals & Slots are used to loosely connect classes. Illustrated by the keyword emit, Signals are used to broadcast a message to all connected Slots. If no Slots are connected, the message "is lost in the wild". So a connection between Signals & 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.

How to start with Qt?

In this series I’ll give you a starting point on working with with Qt. Like I mentioned in Why I love the Qt framework 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.

Why I love the Qt framework

Everyone that knows me, knows that I love the Qt framework. Before I started programming in C++, Java was my primary programming language. I love the generics (yes, some of you will hate me for that opinion right now) and reflection. During my Java-time I used them very often to increase reusability. But while studying we had do learn C++ and I hated it in the beginning. It felt so old and so stiff compared to Java.
