From migration to cross-platform, KDAB's expert Qt consulting and development services specialize in crafting high-quality, performance-driven applications.

Since 1999, KDAB has been the largest independent Qt consultancy worldwide and today is a Qt Platinum partner. Our experts can help you with any aspect of software development with Qt and QML.

The Qt Creator reference card is a handy reference (cheat-sheet) designed to speed up your use of Qt Creator. It gives you keyboard shortcuts for Windows, Linux and Mac.

Explore how KDAB leverages its expertise in Qt, QML, C++, and web technologies to create efficient HTML5 application development stacks. This article discusses best practices for building hybrid applications, integrating Qt WebEngine, and utilizing Qt WebChannel for seamless communication between C++/QML and web clients. Discover how KDAB can help you achieve powerful results by mixing native and web technologies.

The build system for Qt is CMake. What are the benefits of CMake, and how can it help transform your build system? This whitepaper gives you the basic facts so you can take advantage of CMake for building Qt applications.

One of the most difficult choices when starting any new software project is selecting the programming language and framework your team will use to create it. Should you stick with Qt because it’s the best tool for the job? Should you switch to something using web-based technology or designed explicitly for mobile? The choice of a software stack is a strategic decision. Here is a list of considerations that we use to help customers select a software stack that can stand the test of time, whether that’s Qt or something else.

Supervisory control and data acquisition (SCADA) systems have been responsible for the streamlining of any industry that needs precise and consistent controls. However, the UIs of many SCADA devices look antiquated. Even the non-designers responsible for running the system expect their SCADA human-machine interface (HMIs) to have polish and sophistication. This whitepaper provides a quick overview on why KDAB finds Qt to be an ideal tool for building today’s modern SCADA systems.

Learning to create 3D applications can be an overwhelming task even for seasoned developers because of all the new terminology, visual concepts, and advanced math. To simplify the job, many developers use a framework like Qt 3D, which KDAB developed and contributed to Qt. In this paper, the first of 3 whitepapers, you will learn about the structure of a Qt 3D program – the nature of entities, components, and aspects, and how those are incorporated into the scene graph and frame graph. The Qt 3D Basics series is intended to help developers create highly polished Qt 3D applications, including descriptions of the technology components, the rationale behind their designs, and straightforward examples.

The ability to create a 3D applications is a skillset that is increasingly in demand as it plays a crucial role in advanced UX design, virtual reality, game development, and more. While developing a modern 3D program requires many disparate skills, there are frameworks that help the developer stitch it all together. Qt 3D, developed by KDAB, is one such framework. Our first Qt 3D whitepaper helped us understand the structure of a Qt 3D program - the nature of the entities, components and aspects, in the scene graph and frame graph. This paper shows how to incorporate those elements into a functioning program by examining how to receive user input and how to animate objects in a scene.

Parts One and Two of our three part Qt 3D series focused on drawing a 3D model and accepting user input, which are necessary building blocks of 3D applications. For the last part, we’ll look at how to use Qt 3D and frame graphs to create some really sophisticated looking graphics, including how to implement multi-pass rendering.

There are more languages, frameworks and libraries available than ever before, with many of them free or nearly so. But every new tool comes at a cost. In this whitepaper, Kevin Krammer discusses the many benefits to be had from choosing Qt, but also evaluates alternatives to help you decide what's right for you.

If your project relies on MFC, you may find yourself constrained by a legacy framework that limits your ability to leverage modern productivity gains, cross-platform support, and mobile app development. KDAB has extensive experience in migrating MFC projects to Qt, ensuring minimal disruption while modernizing your systems. Discover how to transition effectively and unlock new capabilities for your applications!

Upgrading from Qt 4 to Qt 5 may seem straightforward, but potential pitfalls can complicate the process. Despite Qt 5's design to ease transitions, resource constraints and shifting priorities often delay migration from legacy frameworks. As pressure mounts to adopt newer technologies, discover the essential steps to successfully navigate this upgrade and ensure your project thrives!
