Qt is a cross-platform application framework for desktop and embedded development. It includes an intuitive API and a rich C++ class library, integrated tools for GUI development and internationalization, and support for Java and C++ development.

• An intuitive, easy to use class library
• Integrated development tools
• Cross-platform development on desktop and embedded platforms
• Support for C++ and Java development

Qt sets the standard for high-performance, cross-platform application development. It includes a C++ class library and tools for cross-platform desktop and embedded development and internationalization.

Qt is Comprehensive

Qt is a comprehensive development framework that includes an extensive array of features, capabilities and tools that enable development of high-performance, cross-platform rich-client and server-side applications.

• The Qt Class Library is a growing library of over 400 C++ classes, which encapsulates all infrastructure needed for end-to-end application development. The elegant Qt API includes a mature object model, a rich set of collection classes, and functionality for GUI programming, layout, database programming, networking, XML, internationalization, OpenGL integration and much more.
• Qt Designer is a powerful GUI layout and forms builder, enabling rapid development of high-performance user interfaces with native look and feel across all supported platforms.
• Qt Linguist is a set of tools designed to smooth the internationalization workflow. Using Qt Linguist, development teams can outsource the translation of applications to non-technical translators, increasing accuracy and greatly speeding the localization process.
• Qt Assistant is a fully customizable, redistributable help file/documentation browser that can be shipped with Qt-based applications. With Qt Assistant, development teams significantly speed the documentation process.

Qt is available in three commercial editions: Qt Console Edition, Qt Desktop Light Edition and Qt Desktop Edition.

• Qt Console Edition is an edition of Qt optimized for the development of powerful, GUI-independent back-end and server applications.
• Qt Desktop Light Edition includes all the functionality required for for entry-level GUI application development.
• Qt Desktop Edition provides comprehensive access to a wide range of enterprise-level features needed to develop high-end applications.

Qt is Cross-Platform

Qt is the leading framework for native cross-platform application development. The Qt API and tools are consistent across all supported platforms, enabling developers to learn one API and perform truly platform-independent application development and deployment. Using Qt, development teams can create native applications for all major operating systems - from all major development platforms.

Qt is available for the following platforms:

• Qt/Windows (Microsoft Windows XP, 2000, NT 4, Me/98)
• Qt/Mac (Mac OS X)
• Qt/X11 (Linux, Solaris, HP-UX, IRIX, AIX, many other Unix variants)
