Hello! The question arose whether books exist for studying Qt, but not such as is usually the case, which tell something concrete and too general, but something really worthwhile. I am particularly interested in the whole Qt, starting from its root components, on what everything and how it is built, models, items and other components of this library. It is advisable that the books be in Russian, but if there is no Russian, do not mind reading in English.
Something I did not quite understand your "special" requirements, but if it is useful, here is a list of more or less relevant books in Russian that I know.
Max Schlee "Qt4.8. Professional C ++ Programming"
Borovsky Andrey. "Qt4.7. Practical C ++ Programming"
Blanchett, Summerfield. "Qt4. C ++ C ++ Programming"
