Performance Across Platforms

With Qt, you can develop rich-client applications that run natively – with no emulation layers or virtual machines required – on Windows®, Linux®/X11 and Mac OS® X, all from a single source code-base, delivering lower memory consumption and higher rich-client performance across all the platforms you target.  Native performance: without compromising on portability.

Code Less. Create More.

Qt boosts developer performance too: Qt handles all platform-specific infrastructure, freeing developers to focus instead on creative, innovative development. And Qt's intuitive, easy-to-use API and integrated development tools make cross-platform development a snap:

• The Qt Class Library - the core of Qt. Originally a GUI toolkit, the Qt API has been expanded to include most functionality needed to create nontrivial C++ applications.
• Qt Designer - a fully-fledged GUI builder
• Qt Linguist - a set of tools designed to smooth the internationalization process.
• Qt Assistant - a configurable, customizable help file and documentation reader that can be redistributed with your Qt application.
