I am delighted that roughly 70 people attended my talk "Qt vs. Web - Total Cost of Ownership. Thanks a lot for coming and for the great questions! You can find the video of my talk here. Here are
We have created a custom class, say Person, and use it in a unit test. void TestPerson::testEquality() { Person p1("Alice", 42); Person p2("Bob", 37); QCOMPARE(p1, p2); } The unit test fails with this message.
We have defined a Qt property warningLevel in the C++ class MainModel: Q_PROPERTY(WarningLevel::Enum warningLevel READ warningLevel WRITE setWarningLevel NOTIFY warningLevelChanged) We want to use this property in QML. For example, we want to colour a rectangle according
Security researchers from TrendMicro and the Technical University of Milano explain in a blog post "The Crisis of Connected Cars: When Vulnerabilities Affect the CAN Standard" and a video how to switch off any electronic control unit (ECU)
After offshoring and near-shoring, there is a new outsourcing trend: domestic outsourcing. For example, a company in California outsources work to a company in Indiana or Wisconsin. A New York Times article sheds some light on the reasons for domestic
We have succeeded in building embedded Linux with Yocto for a quad-core NXP i.MX6 (ARM Cortex-A9). Next, we want to cross-compile our own Qt application. As we use CMake for building our Qt application, we must create a CMake
Update: Since Qt 5.12, the QtQuick compiler has been available under LGPLv3. Even if you don't have a commercial Qt license, you will be able to enjoy a significantly faster startup of embedded QML applications. It is
Three years ago aged 45, I started as a freelance software developer in Southern Germany. It were three pretty amazing years. I had paid work for 522.5 days of 750 working days, which amounts to nearly 70% of total

The maize harvest is in full swing. The harvester runs nearly 24/7. The driver notices a drop in the area cut per hour. He calls tech support and starts sharing the screen of the terminal in the harvester. The
Recently, I brought up Qt 5.5 on a Freescale i.MX35, which has an ARM11 CPU but no OpenGL support. Despite the missing OpenGL, I wanted to write the HMI with QML. The additional challenge was that the cross-compilation
In my previous post, I have shown how to use scaling to adapt QML HMIs to different screen sizes and formats. We reach the limits of scaling if we must change the structure of the HMI or if the HMI
