Qt

Qt is a comprehensive, object-oriented development framework that enables development of high-performance, cross-platform rich-client and server-side applications. When you implement a program with Qt, you can run it on the X Window System (Unix/X11), Apple Mac OS X, and Microsoft Windows NT/9x/2000/XP by simply compiling the source code for the platform you want. Qt is the basis for the KDE desktop environment, and is also used in numerous commercial applications such as Google Earth, Skype for Linux, and Adobe Photoshop Elements.

Release Notes: Qt 5.0.2 brings over 600 improvements compared to Qt 5.0.1. Qt Creator 2.7.0 is included in the release package. You can now easily skip modules in configure when building Qt yourself. Static linking now works correctly for the Qt libraries.

Release Notes: This version represents a major overhaul of the C++ GUI programming framework. Key benefits include graphics quality improvements, higher performance on constrained hardware, cross-platform portability, support for C++11, HTML5 support with QtWebKit 2, a vastly improved QML engine with new APIs, and ease of use and compatibility with Qt 4 versions.

Release Notes: This release adds over 100 functional improvements, updates WebKit to version 2.2.2 and libpng to version 1.5.10, and adds 30 improvements to documentation and tools.

Release Notes: Qt Platform Abstraction (QPA) restructures the GUI stack to enable easier porting of Qt to different windowing systems and devices. Threaded OpenGL enables rendering OpenGL from more than one thread concurrently. HTTP requests are now handled in a separate thread by default. The filesystem stack received some heavy lifting under the hood. The result is better I/O performance.

Dear Qt User/Qt Customer:

Trolltech is pleased to announce that we intend to

make Qt 4 for Windows

available under our successful dual licensing

business model.  This means that

Open Source projects under the GNU GPL license

will be able to target all

major operating systems using Qt 4. We plan to

release the Windows Open Source

version of Qt at the same time as Qt 4.

==

So now everyone can finally stop using that inferior

toolkit with 3 letters ;)
