Qt is a cross-platform application framework. With its intuitive functions for thread, data and object management, high-level concurrency APIs and cross-platform portability, Qt is an ideal choice for developing applications that squeeze maximum performance out of multi-core systems.

Why use Qt for multithreaded development?

Powerful, straightforward C++ threading classes

Type-safe inter-thread communications

Code once, target multiple desktop and embedded platforms

Parallel programming without low-level primitives

Automatically scale to take maximum advantage of multi-core systems

More and more software applications we use today perform multiple tasks concurrently and seamlessly. Any application that must perform multiple parallel tasks can benefit from multithreading. With the increasing popularity of multi-core processors, in not just desktops, but also high-end embedded systems, multithreading can improve not just response times, but also runtimes. However, the challenge of incorporating multithreading in an application can be daunting, especially in the absence of a high-level interface for managing threads. Qt -- a cross-platform application framework -- offers a range of features, including intuitive C++ APIs, that vastly simplify programming of multithreaded applications.

In this paper, we will discuss the common challenges faced by developers of visualization software, and present techniques for using C++ to easily integrate advanced 2D and 3D graphics into native, high-performance applications. Using the Qt® application framework, we will demonstrate how these techniques speed visualization development, and enable deployment across multiple operating systems from a single codebase.

The use of XML as way to share structured data across information systems on- and offline is increasing, however effectively using XML data in your application can be cumbersome, demanding many lines of complex code. This whitepaper discusses how to put XML and other structured data to work in your application with XQuery the standard language for querying XML data, -- vastly simplifying the use of XML in the Qt application framework.

If you are leading a software development project today, you probably start with one very basic choice can I make this work on the web? More and more, the default answer tends to be yes. Find out how Trolltech has made it easy for developers to implement web content directly into their native applications through the integration of the WebKit rendering engine.
