So far programs using Qt OPC UA with the open62541 back-end produced quite a bit of chatter on stdout originating from the open62541 stack itself. Unfortunately there was no simple way to get rid of these low-level logs. We now provide a way to control this behavior.
Porting a Qt 5 QML application to Qt 6 doesn’t have to be difficult. We want to share the issues we had and how we solved them. Look out for your shaders and modules.
Something that has traditionally been complicated to achieve in Qt/QML, especially on low end hardware, is high performant list scrolling with complex delegates.
This has recently changed. In Qt 5.15, it is as simple as setting the new QML ListView property called reuseItems to true. For more details, have a look at the documentation.
In this blog post, I will explain how you can implement this feature in Qt Versions prior to 5.15.
Protobuf is a great choice to transfer data from a IoT device into the cloud. This blog will show you what Protobuf is, how it can be used with C++ and Javascript and how to handle updates without breaking backwards compatibility.
In the first part of our series, we will connect a Qt app to the Microsoft Azure IoT Hub, use the Device Twin and show you how to authorize your IoT device to the cloud.
IoT and IIoT applications are special compared to other kinds of cloud applications as they have to deal with devices existing “outside” of data centers.
The following series of articles provide an end-to-end overview of what Microsoft Azure offers to handle some of the challenges involved in connecting an IoT Device with the Cloud.
By working through this series you will learn about the major concepts involved in getting your IoT/IIoT device connected to Microsoft Azure. In our examples we will feature Qt, Node.Js, Protobuf from Google and much more to get you started.

Continuous Delivery and Continuous Integration are related disciplines. Continuous Delivery is the ability to get changes to the users, safely and quickly in a sustainable way . A Continuous Delivery process achieves this by ensuring that code is always in a deployable state even when making changes on a daily basis.
Builds that take a lot of manual work are highly error-prone. Make sure to have a good foundation for your project by implementing automated builds.
