Описание: As PyQt’s creator, I’m delighted to see that this book has been written. Although
I served as one of the book’s technical reviewers, I’m happy to confess
that I learned a few things myself.
The PyQt documentation covers the APIs of all the PyQt classes. This book
shows you how to use all those classes, how to combine them to create dialogs,
main windows, and entire applications—all of which look good and work well,
with no arbitrary limits, and using a programming language that is a joy
to use.
What I particularly like about the book is that the examples aren’t trivial ones
designed to illustrate a simple point, but are potentially useful in their own
right. Theway that different approaches are considered will reward the reader
who wants to develop a deeper understanding of how to apply PyQt to the
development of large scale, production quality applications.
I began the PyQt story back in the late 1990s. I had been using Tcl/Tk for
some time, but I felt that Tk applications looked ugly, especially when I saw
what had been achieved with the first version of KDE. I had wanted to switch
to Python, and so I thought I would combine the change of language with a
change of GUI library.
Initially I used some wrappers that had been written using SWIG, but I concluded
that I could produce a more suitable wrapper tool myself. I set to work
creating SIP, and released PyQt 0.1 supporting Qt 1.41 in November 1998.
Development has continued regularly ever since, both to keep up with new releases
of Qt and to broaden the scope of PyQt with, for example, the addition
of support tools and improved documentation. By 2000, PyQt 2.0 supported
Qt 2.2 on both Linux and Windows. Qt 3 support appeared in 2001, and
Mac OS X support in 2002. The PyQt4 series began with PyQt 4.0 in June 2006
with support for Qt 4.
My primary goal has always been to allow Python and Qt to work together in
a way that feels natural to Python programmers, while allowing them to do
anything they want in Python that can be done in C++. The key to achieving
this was the development of SIP. This gave me a specialized code generator
over which I had complete control and ensures that Python and Qt will always
fit snugly together.
The essential process of developing and maintaining PyQt is now well established.
Much of the work isnow automated,which means that keeping up with
new releases of Qt from Trolltech is no longer the problem it once was, and ensurs
that PyQt will continue for years to come.
It’s been very gratifying to watch the growth of the PyQt community over the
years. If this book is part of your introduction to PyQt, then welcome!
