Good and up-to-date QT book?

[Asperamanca]

Hi,

I'm looking for a good, concise, well-structured book covering C++ development with QT. Ideally, it would serve both as a learning tool and a reference.

Recommendations?

I've seen "C++ GUI Programming with Qt4" and it looks good. Anyone knows it? Is there a new, upcoming edition (the last one is more than a year old)?

The three nice books are the one you mentioned, "Qt Book" by one of the KDE contributors and "Foundations of Qt Development" by Johan Thelin. For obvious reasons I consider the last one the best. Unfortunately all of them slowly become outdated.
