Book Description

Cross-platform development is a kind of holy grail, and Trolltech’s Qt toolkit may well be the most promising solution yet to this development challenge. Qt is widely used for the development of GUI applications as well as console tools and servers, and it’s especially appealing to programmers who need to write cross-platform applications to run on Linux/Unix, Mac, and Windows machines without having to rewrite for each platform.

The Book of Qt 4 offers an in-depth explanation of Qt 4 that goes beyond the common focus on C++ programming. Author Daniel Molkentin uses practical examples to explain features like the signal/slot concept and the event system, as he guides you through developing applications with and without Qt’s graphical GUI builder, Qt Designer. And as a core KDE developer, Molkentin’s head is full of real-world problems and solutions that he peppers liberally throughout The Book of Qt 4, making it a resource that you’ll consult time and again. You’ll find coverage of:

• Tools for creating dialogs
• GUI design with the Qt Designer
• Widget layout and dialog construction
• Data visualization using Qt’s model/view concept
• The QtSql module and the graphics library Arthur
• File handling, XML, processes, and network connections
• Databases and threading
• Event handling and using drag and drop Download Now »

Book Description

Physics for Flash Games, Animation, and Simulations teaches ActionScript programmers how to incorporate real physics into their Flash animations, games, user interfaces, and simulations.

• Introduces Flash physics in an accurate, but approachable way, covering what is required to produce physically realistic simulations (as opposed to animations that look roughly right)
• Packed full of practical examples of how physics can be applied to your own games and applications
• Addresses the diverse needs of game developers, animators, artists, and e-learning developers

The book assumes a basic knowledge of ActionScript and Flash. However, no previous knowledge of physics is required—only some very basic math skills. The authors present everything from basic principles to advanced concepts, so you’ll be able to follow the logic and easily adapt the principles to your own applications. The book builds on your physics knowledge, enabling you to create not only visual effects, but also more complex models and simulations.

What you’ll learn

• Basic math and physics you’ll need to incorporate realism into your games, animations and simulations
• How to incorporate a wide range of forces, including environmental forces such as gravity and friction, and forces due to fluids, such as drag and upthrust
• How to build a number of realistic simulations, like submarines and flight simulators Download Now »
