KDAB is delighted to offer, with our partners The Qt Company and Software Compliance Academy, 9 superb one day training classes to kick off the QtDevCon event in Berlin this summer – June 13th – 15th. Each class is led by an expert in the field with content that is slap up-to-date and derived from comprehensive longer courses.
As well as a wide range of more obviously Qt-focused courses, subjects offered range from the oft-overlooked but vital FOSS Compliance that every developer should be aware of to the nitty gritty on What’s New in C%2B%2B20 – not for the faint-hearted.

JSONify All Things
Extending the nlohmann/json Library
|

|

|

The nlohmann/json library is everything a developer can expect from a modern library . . .
However, it has one problem that is widely mentioned across the internet, which I’ll tell you about below. Various solutions to the problem have been developed and shared, but none seem to be easy-to-use.
In this blog post, we will see how one can serialize and deserialize almost anything by extending the library a bit.
Read on.
Hear more about it in this month’s KDAB News.

C%2B%2B23 is feature complete and on track to be released next year. . .
In this blog post, I want to talk about what I think is my favorite feature of C%2B%2B23: the really keyword. This is a brand new keyword that can be used in a number of different scenarios. Let’s explore them together to understand the usefulness of it.

In Qt Creator, there is a line edit which has a push button embedded in it for selecting tokens. How did they do that?
In this episode, Jesper investigates and implements a file chooser based on this idea.
Watch the video.

Jesper starts this episode by bashing Qt 3, where you could write update(false). What does that mean? Do not update?
Watch and find out.

If you have a Java or C%2B%2B98 background, or similar, your finger memory may reach for the subclassing tool in your toolbox whenever you face a problem.
In this episode, Jesper shows an example where subclassing indeed isn’t the right tool in modern C%2B%2B.
Watch the video.
