I've been working with C/C++ for a few years now, and with Qt for 1-2 years...mainly with Qt4 in embedded systems. I have a couple of the (very thorough) Qt4-based books that are available here on Amazon, and they are very good. In fact, they are almost TOO good from the standpoint that they nearly overwhelm you with information. But as reference material, they are extremely valuable. That being said however, when I saw that this book was dealing with Qt5 I wanted to go ahead and read it.
I read both of the reviews posted previous to mine, before buying the book. Then I purchased the Kindle version of this book and worked through the first couple of chapters. I can definitely see the criticism(s) noted in Keith Peter's review. It's pretty apparent that this book did not have a good Technical Editor to go through it, because there are a number of simple errors that should NOT have made it through. For example in chapter 2, here's one such example:
"...In other cases, we have to explicitly set the parent for a QObject child so that the parent can take over its ownership and manage the release of its memory. Hence, we pass the QObject parent, which is this, a MainWindow class to the constructor of QTimer."
It's unfortunate that the author doesn't point out that the "this" pointer is a pointer to the instance of a class that is currently being referenced. In other words, "this" isn't a class...it's a pointer to an instance of a class.
There are a number of similar such errors in the first two chapters, but overall the intent of the author is very good I think. But as I stated above, the book is in dire need of a good Technical Editor to go through and point this out to the author. I have served as a Technical Editor for a book on embedded systems, and it's not an easy task. It take many hours of work to go through a book such as this, but the result is well worth the effort.
So overall I'll want to come back and revisit this review after finishing the book, but for now I would have to give it a 4-stars due to poor editing. I would have to agree with Keith on this point. I would also add that you really do need to have some C++ experience before working through this book, as that is assumed--and it would also be most helpful to know something about Qt (and Qt Creator) before reading this book. While it's not absolutely imperative that you have used Qt before, there are many times that the author chooses not to go into elaborate detail on a take he asks you to perform. If you are at least somewhat experienced with Qt Creator you will have little problem getting things accomplished--but you might struggle a little but if you've never used the IDE before. On the other hand it will make you dig more for the answer(s), so I suppose that's not all bad.
