Our projects


We are passionate Qt users and contributors, dating back to the early 2000s. With such a long tenure, we have used and experienced almost every piece of it daily, and frequently worked on them, too. With Qt being an open source project, no matter which product or client we are working on - we frequently contribute changes back.

Gunnar is an expert with all things graphical, and has intimate knowledge of OpenGL and QtGui, especially QPainter, as well as the QtQuick Scene Graph implementation.

Robin knows QPA and QtCore like the back of his hand, and has also dabbled extensively with QtNetwork. He spends most of his spare time working on QtQuick now.

If you need help with Qt - either in creating your own product, or working on the framework itself to fix bugs or add features - then we would be most happy to help. Take a look at our services, and then get in touch!

Here's a list of just some of the things we have done:

  • Added journald logging to QtCore
  • Added TUIO touch protocol support to QPA
  • Wrote the QtQuick Scenegraph, used in QtQuick 2
  • Wrote custom QPA plugins for non-standard windowing systems
  • Improved the performance of various parts of Qt, QtQuick, and QML
  • Participated in the design of the current QPainter architecture, including implentation of the raster paint engine
  • Fixed a whole host of bugs :-)

Open source

We have worked on a wide variety of projects in open source, including creating some of our own. Here's a non-exhaustive list:

Title Description
rengine A rendering engine. An experiment into a more efficient framework for developing graphical applications specifically for embedded systems.
qmlbench A benchmarking framework for evaluating the creation and rendering performance of individual QtQuick components (such as a button, or all the way down to Rectangle).
dqml A tool for live-coding with QML. Use dqml instead of the qml or qmlscene tools, and dqml will reload whenever anything in your code changes, leading to a much faster think-code-test cycle.
tuio2qt A QPA plugin for Qt, allowing sending touch events to Qt over a network using the TUIO protocol. Note that this plugin was subsequently released with Qt, but the repository remains for allowing use with older Qt versions.

From time to time, we may release new projects. Feel free to check out our Github, where we host most of it.
