As a developer of training material, we are of course active as training providers. We have experience with different teaching situations ranging from guest lectures at universities, half-day introductory courses to full, multiple-days courses. Our training material covers Qt and embedded Linux, but custom training sessions can be developed for your specific needs.
For the curious reader, we can recommend having a look at Foundations of Qt Development (ISBN 1-59059-831-8) available from Apress. The book covers Qt 4.2 and has been written by our Qt trainer: Johan Thelin.
