Introduction In the previous article we gave an overview of the process for creating a custom aspect and showed how to create (most of) the front end functionality. In this article we shall continue building our custom aspect by implementing the corresponding backend types, registering the types and setting up communication from the frontend to […]
Introduction Qt 3D has a flexible and extensible architecture that allows us to easily add our own new functionality to it without disrupting the existing features. The functionality of Qt 3D is divided among so-called aspects, each of which encapsulates a particular subject domain such as rendering, input, or animation. This short series of articles […]
Sometimes data visualization might call for more than a graph – you need to visualize complex data, such as that generated by city lighting, in three dimensions to get the full effect. KDAB decided to put together a showcase for the Qt World Summit that allowed us to demonstrate Qt 3D’s capabilities as a performant […]
Introduction This article is part of a blog series about Clang Tidy. In the previous article we learned about the general usage of Clang Tidy to automatically refactor source code
As my first subject for this animation blog series, we will be taking a look at Animation curves. Curves, or better, easing curves, is one of the first concepts we are exposed to when dealing with the subject of animation in the QML space. What are they? Well, in simplistic terms, they are a description […]
This blog series will introduce the clang-tidy utility from the Clang/LLVM project and show how to use it to automatically refactor
Functional Safety is the term used for systems designed to minimize risk to human health. But there’s a dilemma in today’s tech-driven world. We are more reliant than ever on software to control our planes, trains, cars, and boats, to operate our medical equipment, to process our food, to clean our water, and to power […]
Starting with Qt 5.7, we added the ability to create Android services using Qt. In this article we’re going to see how to get started and also how to communicate between the two. Before we get started I want to add a big bold WARNING about the performance! Because the services are run in the […]
Some time ago, I wrote a code to restart the running application on Android. You might well ask why such a thing was needed. It was needed because there are cases where, whenever a user changes the theme, the application has to restart to apply the change (it can’t be applied on the fly). In […]
To get you started on this, we’ll be using KDAB’s Android utils with the humble Toast. Toasts are small popups which are used to show the user some feedback. Check Google’s API guide for more info about toasts. The easiest way to show a toast is to use Toast.makeText(Context context, CharSequence text, int duration) static […]
