Wysota Witold :
Witold Wysota is a software architect and developer living in Poland. He started his adventure with Qt in 2004 when he joined QtForum.org and started answering questions about programming with Qt and shortly afterwards became part of the moderator group of the forum. In 2006, together with with the the moderator team, he established QtCentre.org which quickly became the largest community-driven support site devoted to Qt. For a number of years he conducted commercial, academic and public trainings, workshops, has given lectures on Qt, Qt Quick and related technologies. He is a certified Qt developer and was a member of Qt in Education Advisory Board with Nokia where he helped preparing materials for using Qt in educational activities. Witold was also a technical reviewer of Foundations of Qt Development by Johan Thelin, a book about Qt4 and an author of a couple of articles on programming with Qt. In real life Witold is a passionate adept of Seven Star Praying Mantis, a traditional style of Chinese martial arts. I would like to thank all people who have worked on Qt development over the years for creating such great programming framework which was the main force shaping my programming career. I would also like to thank Lorenz for helping me with the book as well as Packt for magnitudes of patience towards me during the process of creating this book.Haas Lorenz :
Lorenz Haas is a passionate programmer who started his Qt career with Qt 3. Thrilled by Qt's great community, especially the one at QtCentre.org, he immerses himself in this framework, became one of the first certified Qt developers and specialists, and turned his love for Qt into profession. Haas is now working at a medium-sized IT-company based in Erlangen, Germany, as a lead software architect. He mainly develops machine controls and their user interfaces as well as general solutions for the industry sector. Additionally he runs his own small consultancy and programming-business called Histomatics. You can contact him at qtbook@histomatics.de. A few years ago he started contributing to Qt Creator. He added a couple of refactoring options you probably rely on a regular basis if you use Qt Creator. He is also the author of the it's Beautifier plug-in. I would like to thank Witold who guided my fist steps into the Qt world back in the days and who still is assisting me with any problems that may arise today. I am also very grateful to him for taking me on board for this book-writing project. He's an excellent teacher and tutor! Second, I would like to thank the team at Packt who helped and guided us through the entire process of writing this book.
