Qt 5.3.2 / 5.4.0 Beta

An SDK and GUI toolkit solution that allows developers to create rich graphical user interfaces
Qt is an open source project that works as a cross-platform SDK (Software Development Kit) and GUI toolkit with APIs for C++ programming. It is a cross-platform framework, supporting the Linux, Microsoft Windows and Mac OS X operating systems.

The project is comprised of the Qt framework, which includes intuitive APIs for C++ and CSS/JavaScript-like programming languages, Qt Creator IDE, a powerful and cross-platform integrated development environment, as well as several other tools and toolchains.

While Qt Creator comes with UI designer tools and on-device debugging functionality, the included tools and toolchains provide Qt developers with everything they need, from simulators and local or remote compilers, to internationalization support and device toolchains.

When installing the program in any Linux-based operating system, it will provide users with several command-line and graphical utilities that can be used to configure the look and feel of Qt applications, as well as to compile Qt programs or choose the default version to use, if multiple ones are installed.

A graphical application called Qt Configuration will allow users to select how the Qt application will blend in the current desktop environment. For example, you can use Qt apps in the GNOME desktop environment and they will look the same as existing GTK+ apps.

In addition, you can also choose a default font, enable GUI effects, modify feel and global strut settings, as well as to configure the Phonon multimedia framework component (if available).

The Qt UI creation toolkit will allow users to create rich, touch-enabled graphical user interfaces and applications in a timely manner. It aims to combine the Qt framework with tools designed for the creation of applications for Symbian phones and the Nokia N9 smartphone.

Summing up, Qt is a strong rival to existing open source GUI toolkits, such as the highly acclaimed GTK+ project. It provides some unique features, compatibility with other GUI styles, as well as platform independence.

What's New in version 5.4.0 Beta
  • Powerful Web Offering with Qt WebEngine:
  • As the importance of HTML5 has grown we want to provide the best support for HTML5 within the Qt technology offering. The Qt WebEngine, a long-term R&D project based on the Chromium web engine has now reached fully supported version on desktop and embedded platforms.
  • Qt WebEngine provides a convenient API for both Qt Widgets and Qt Quick for using the Chromium web engine. Besides plain web viewing purposes Qt WebEngine takes full benefit of the whole Qt graphics stack integration allowing you to mix and overlay native Qt controls with web contents and OpenGL shaders. Of course, the fact that Qt provides a full application framework around the web engine makes Qt WebEngine truly an unparalled web engine API.
