Which book to learn ?
I'm looking for a book explaining Qt5 (not Qt Quick or others for a start) explaining how does Qt work and with plenty of examples from beginner to confirmed.
My problem for the moment is that I can have serious trouble to (for example) build a simple QTreeView, while I have no problem manipulation of a QTableWidget...
Like many self-learners, there are gaps...
Here here you have a set of books that should get you started.
Note that the Qt 4 books are still very relevant. The theory itself is still pretty valid e.g. for the Model View Framework, nothing as changed in the way they should be used.
This one is free and not very outdated
I liked how he explained things but your mileage might vary.
