I am interested in preparing the Qt Essentials Cerificate and for that I would like to buy a book (only one or maximum two). I saw the books that are listed "here":http://qt.nokia.com/learning/certification/exams/preparation-prerequisites/qt-curriculum/qt-essentials/materials, these are:
C++ GUI Programming with Qt 4, 1st and 2nd Edition, by Jasmin Blanchette, Mark Summerfield.
Foundations of Qt Development, by Johan Thelin
An Introduction to Design Patterns in C++ with Qt 4, by Alan Ezust, Paul Ezust
The Book of Qt 4: The Art of Building Qt Applications by Daniel Molkentin
But apparently no one treats completelly all the exam's subjects. Could you tell me (if you know them) which is the best ?
Thanks in advance!
