The Insider's Best-Practice Guide to Rapid PyQt 4 GUI Development

Whether you're building GUI prototypes or full-fledged cross-platform GUI applications with native look-and-feel, PyQt 4 is your fastest, easiest, most powerful solution. Qt expert Mark Summerfield has written the definitive best-practice guide to PyQt 4 development.

With Rapid GUI Programming with Python and Qt you'll learn how to build efficient GUI applications that run on all major operating systems, including Windows, Mac OS X, Linux, and many versions of Unix, using the same source code for all of them. Summerfield systematically introduces every core GUI development technique: from dialogs and windows to data handling; from events to printing; and more. Through the book's realistic examples you'll discover a completely new PyQt 4-based programming approach, as well as coverage of many new topics, from PyQt 4's rich text engine to advanced model/view and graphics/view programming. Every key concept is illuminated with realistic, downloadable examples—all tested on Windows, Mac OS X, and Linux with Python 2.5, Qt 4.2, and PyQt 4.2, and on Windows and Linux with Qt 4.3 and PyQt 4.3.

Coverge includes

• Python basics for every PyQt developer: data types, data structures, control structures, classes, modules, and more

• Core PyQt GUI programming techniques: dialogs, main windows, and custom file formats

• Using Qt Designer to design user interfaces, and to implement and test dialogs, events, the Clipboard, and drag-and-drop

• Building custom widgets: Widget Style Sheets, composite widgets, subclassing, and more

• Making the most of Qt 4.2's new graphics/view architecture

• Connecting to databases, executing SQL queries, and using form and table views

• Advanced model/view programming: custom views, generic delegates, and more

• Implementing online help, internationalizing applications, and using PyQt's networking and multithreading facilities

The girl's name is Penny Lane (really!). Homicide Johnny West had been called in to solve the murder of Harry Waters whose newspaper columns had ruined many men. But the web of violence grew and murder followed murder until Johnny and his co-worker, Penny Lane, found out they were next in line.

Python 3 is the best version of the language yet: It is more powerful, convenient, consistent, and expressive than ever before. Now, leading Python programmer Mark Summerfield demonstrates how to write code that takes full advantage of Python 3’s features and idioms. The first book written from a completely “Python 3” viewpoint, Programming in Python 3 brings together all the knowledge you need to write any program, use any standard or third-party Python 3 library, and create new library modules of your own.

Summerfield draws on his many years of Python experience to share deep insights into Python 3 development you won’t find anywhere else. He begins by illuminating Python’s “beautiful heart”: the eight key elements of Python you need to write robust, high-performance programs. Building on these core elements, he introduces new topics designed to strengthen your practical expertise—one concept and hands-on example at a time. This book’s coverage includes

• Developing in Python using procedural, object-oriented, and functional programming paradigms
• Creating custom packages and modules
• Writing and reading binary, text, and XML files, including optional compression, random access, and text and XML parsing
• Leveraging advanced data types, collections, control structures, and functions
• Spreading program workloads across multiple processes and threads
• Programming SQL databases and key-value DBM files
• Utilizing Python’s regular expression mini-language and module
• Building usable, efficient, GUI-based applications
• Advanced programming techniques, including generators, function and class decorators, context managers, descriptors, abstract base classes, metaclasses, and more

Programming in Python 3 serves as both tutorial and language reference, and it is accompanied by extensive downloadable example code—all of it tested with the final version of Python 3 on Windows, Linux, and Mac OS X.
