Welcome to January, 2022

This month we are Introducing KD Bindings: Reactive Programming and Data Binding in C++, while Loose Coupling with Signals and Slots: Connecting (Almost) Any Function to a Signal, goes into some of the details.

 

Jesper Pedersen and family add four more lessons to the Qt Widgets and More series and there's more news about (real) Events, including the opening of ticket sales to our Qt Developer Conference!

 

Enjoy!

Introducing KDBindings

Reactive Programming and Data Binding in C++
­
­
­
­

by Sean Harmer

All Qt developers should know about signals, slots, and properties. Those of you who have used QML will know that property bindings are super useful and cool. Bindings allow us to write more reactive and declarative style code. However, they are only available within QML, which means there are no compile time errors when you do something wrong.

 

Until now . . .

Loose Couplings with Signals and Slots

Connecting (Almost) Any Function to a Signal 
­
­
­
­

by Leon Matthes
­

Leon gives an in-depth look under the hood and provides numerous code examples to help you make the best of KDBindings where loose couplings are what you're dealing with.

 

Read the blog.

See Leon's interview about it in January's KDAB News.

Linux, & qDebug

See how to back up your source files every 10 minutes on Linux, then Jesper offers some useful techniques involving qDebug.

Events in 2022
­

Before we kick off with the Events for 2022, we thought you'd like to listen to this podcast: ‘Building the Open Metaverse'. Born out of a BOF session at last year's SIGGRAPH, it's driving the conversation around interoperability and open standards, addressing such questions as ‘Can we get USD and GLTF on a converging path?’. Take some time out and find out about the real Metaverse, from the bleeding edge.
