资源说明：This book teaches how to write GUI applications using the Python programming
language and the Qt application development framework. The only
essential prior knowledge is that you can program in some object-oriented programming
language, such as C++, C#, Java, or of course, Python itself. For the
rich text chapter, some familiarity with HTML and with regular expressions is
assumed,and the databases and threading chapters assume some basic knowledge
of those topics. A knowledge of GUI programming is not required, since
all the key concepts are covered.
The book will be useful to people who program professionally as part of their
job, whether as full-time software developers, or those from other disciplines,
including scientists and engineers, who need to do some programming in support
of their work. It is also suitable for undergraduate and post-graduate students,
particularly those doing courses or research that includes a substantial
computing element. The exercises (with solutions) are provided especially to
help students.
Python is probably the easiest to learn and nicest scripting language in
widespread use,and Qt is probably the best library for developing GUI applications.
The combination of Python and Qt, “PyQt”, makes it possible to develop
applications on any supported platform and run them unchanged on all the
supported platforms—for example, all modern versions of Windows, Linux,
Mac OS X, and most Unix-based systems. No compilation is required thanks
to Python being interpreted, and no source code changes to adapt to different
operating systems are required thanks to Qt abstracting away the platformspecific
details. We only have to copy the source file or files to a target machine
that has both Python and PyQt installed and the application will run.
If you are new to Python:Welcome! You are about to discover a language that
is clear to read and write, and that is concise without being cryptic. Python
supports many programming paradigms, but because our focus is on GUI
programming, we will take an object-oriented approach everywhere except in
the very early chapters.
