Improving Performance Across Platforms with Qt and Multithreading
|
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. |

Improving Performance Across Platforms with Qt and Multithreading
[PDF: 14 pages]
More and more software applications we use today perform multiple tasks concurrently and seamlessly. As the audio player streams audio from the net, it also decompresses it, updates the display, and scans the disk for new songs. A video editor responds to the user changing the storyboard, while previewing the video. A code editor pops up appropriate prompts as the programmer types, even while it parses the code for highlighting the syntax of what has already been typed.
Any application that must perform multiple parallel tasks can benefit from multithreading. Multithreading can provide a solution to the more common problem of simply keeping the interface attractive while the program is busy. 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 is a cross-platform application framework with a range of features, including C++ APIs that vastly simplify programming of multithreaded applications. By subclassing Qt’s base classes for multithreading, you inherit a rich set of capabilities based on our years of experience addressing the challenges of this type of programming.
