Qt Container in Qt 5 and Qt 6 - Video

What's a container? Maybe you know them under another name (collections, sequences, ...): they are data structures that can hold (arbitrary) amounts of data. Think about lists, associative arrays (maps), and so on. For various reasons, detailed in these videos, Qt ships with its own family of containers, even if you're using Qt with a language (C++, Python) that also has them!

So what are the features of Qt containers? Should you use them? How are they different from the ones coming from the C++ Standard Library? Have the Qt containers changed between Qt 5 and Qt 6? This video series will give answers to these questions.

"Who cares about containers, anyways?" That's a fair point; one may as well answer: "everybody!". Any non-trivial application needs to use some container to hold data. Maybe most of the time a developer won't care about picking a specific one... except in the cases where they do, and then the knowledge that these videos will provide will be useful :-)

This first video acts as an introduction to the whole series. We will discuss what are the history and the common features of the Qt containers.
