Mark Summerfield owns Qtrac Ltd., where he works as an independent consultant, programmer, author, editor, and trainer specializing in C++, Qt, Python, and PyQt. During nearly three years as documentation manager for Trolltech (now Nokia's Qt Development Frameworks), he founded and edited the Qt Quarterly technical journal. His books include Rapid GUI Programming with Python and Qt (Prentice Hall, 2008) and Programming in Python 3, Second Edition (Addison-Wesley, 2010). With Jasmin Blanchette, he coauthored C++ GUI Programming with Qt 4, Second Edition (Prentice Hall, 2008).

"A good book on advanced Qt programming has been missing in the arsenal of Qt programmers. I'm very happy that Mark has written one. He is a fantastic technicalwriter with all the necessary background to write authoritatively about Qt programming. ... In other words: You are in for a treat! You are holding in your hands an excellent opportunity to expand on your knowledge of all the cool stuff you can do with Qt." --Eirik Chambe-Eng, cocreator of Qt
