Welcome to our June Newsletter

First, a note from me: from next month the KDAB Newsletter will be sent out by Sebastian Springer so I can make trouble elsewhere in my 75th year. Time for a change ;-). Please welcome him, especially in your inbox.

 

I bid you farewell with Anchoring Qt Quick Components Instantiated with JSON, followed by Parts 1 and 2 of Mastering the Embedded Update Process.

 

We also bring you QtTest Extension for VSCode, some changes to KDAB Training and this month's video releases, including Module 4 of Introduction to Qt Widgets. Finally, we have a short selection of Events worth attending. Closing date for entry to FlutterCon is imminent, so grab a ticket while you can!

Anchoring Qt Quick Components Instantiated with JSON

Factory Design Techniques - Parts 3 & 4

by Javier Cordero Pérez

This is the final entry of the Factory Design Techniques series, which looks at simple architecture for remote real time instantiation and updating of arbitrary QML components. 

 

Part 1 focused on software design patterns while Part 2 showed how to use QML's positioning and layout APIs.

 

In this post, Parts 3 and 4 combined, Javier evaluates a technique for anchoring nested components to mitigate remote code execution risks.

QtTest Extension for VSCode

Introducing QtTest Runner

Qt Test is a framework designed for unit testing applications and libraries built with Qt. It provides all the standard features commonly found in unit testing frameworks, making it easier to write unit tests for Qt-based projects.

We’re happy to introduce the QtTest Runner – a Visual Studio Code extension for running Qt Tests via the test explorer pane.

Introduction to Qt Widgets

Module 4 is released

This latest Module from Jesper - and it's a short one so you can get outdoors while the sun shines - focuses on Dialogs and Main Windows.

 

Here's the link to the previous module, Module 3, The Whirlwind Tour, in case you missed it.

Dialogs

Why you need QDialog, (the same reason your Mum is not actually a stone ;-) ). The difference between a modal and non modal dialog, and how you create your own is also covered.
