For some time I have wanted to write a Qt book that covered topics that were
too advanced for C++ GUI Programming with Qt 4,★ even though that book
itself has proved quite challenging for some readers. There is also some
specialized material—not all of it difficult—that I wanted to cover that simply
does not belong in a first book on Qt programming. Furthermore, in view of
the sheer size of Qt, no one book can possibly do justice to all that it offers, so
there was clearly room for the presentation of new material.
