Welcome to our February newsletter

This month we focus on using Qt for all parts of a mobile application and it’s cloud backend with Qt Allstack I – Setup – Creating a Realtime Mobile Chat App followed by Qt Allstack II – Adding Firebase. Then, following on from last month’s theme, there’s more on Data Bindings and a 6 more new videos including three from this month’s blog author, Daniel Nicoletti.

To round off, we bring you the latest updates on Events, including Qt Developer Conference. We invite you to join us in Berlin in June! Find out more below.

Qt Allstack I – Setup

Creating a Realtime Mobile Chat App

by Daniel Nicoletti

Writing mobile apps can be a lot of fun, especially with Qt and QML. But if your background is all about C++ and Qt, writing the entire required stack for a mobile app can be challenging.

Don’t give up! Read on.

Qt Allstack II – Adding Firebase

by Daniel Nicoletti

Now that we have a functional chat application, it’s time to add real world features, like push notifications. Firebase Cloud Messaging allows you to send push notifications to your users while your app is not running and integrates with APNs (Apple Push Notification services). This way, you only care about one API and can have push notifications on both Android and iOS.

Read on.

Data Bindings in C++ and more

an interview with Leon Matthes in KDAB news

Last month we introduced KDBindings. In this interview, Leon, who wrote a follow-up blog on Loose Coupling with Signals and Slots, talks about how KDAB came up with the idea of making it possible to do reactive programming and data binding in straight C++, and adds a bit more on the subject.

Other Videos this month

We’re happy to offer you a new series this month from longtime KDE Contributor and author of many open source projects, such as Apper, Cutelyst and ASql: Daniel Nicoletti.

Daniel kicks off with tips for avoiding Qt application freeze when querying a database, then he demonstrates how to create both a mobile application and its web backend. Next he talks about adding Firebase push notifications, all as discussed in his blogs above.

Asql and Cutelyst from Daniel Nicoletti
