Qt framework is useful for GUI design because it is faster than other languages, is managed directly by the CPU, and uses smart memory management. Key features that make Qt attractive include being cross-platform, supporting both desktop and embedded platforms, allowing code to be written in C++ and compiled to native binaries, being open source and well maintained, having a capable GUI designer and IDE, and allowing new ways to develop apps for devices using QML and JavaScript. The author developed the same application in Java and Qt, finding it ran 5 or more times faster in Qt.

- 1. Encoding Enhancers PvtLtd IIOT Solutions 1 Qt framework usability Why do we use Qt framework? Qt is better for GUI design,because is faster than other languages; Is managed directly by the CPU; Uses smart Memory management. It's GUI Designer is very useful and easy to handle!! Key features that make it attractive are: It's cross-platform and it uses the system's resources to draw windows, controls,etc so your application will get a native look (e.g on a Mac your app window will be lacking the menu bar and the menu bar will appear on the system's menu bar as it is the standard behavioron the Mac platform). It is not just cross platform across desktop platforms namely - Windows, Mac OS and Linux but also the same code will work on the devices based on Embedded Linux, Windows CE/Mobile, Symbian and the newly coming Meego.For embedded linux it has its own light weight windowing system based on framebuffer eliminating the need for X11. Writing in C++ gives you great control, the possibility to work with fantastic libraries like the STL, Boost, etc; and your code is compiled to native binaries that will run at full speed without the need for a virtual machine. Qt is open source and is developed by the Qt Group (formerly Trolltech) at Nokia so you have a very large enterprise maintaining it with the support from the community and ensuring it's evolution. It has the best GUI designer I've ever seen (I have worked with .NET before using both Windows Forms and WPF) It now also has a very capable IDE in Qt Creator which again works on all platforms and hence gives you same development environment where ever you go. The latest 4.7 is coming with a new way of developing apps for devices using QML+Javascript for your fluid multi touch gesture enabled interface talking directly to the business logic done in C++ Qt classes. The same is true for Qt Webkit based on Webkit toolkit where you can connect yourjavascript code to yourcore C++ classes done in Qt. I have made the same application on Java and QT, and runs like 5 o more times faster on QT
