Version 5.4 uprates Digia Qt’s hybrid development capabilities, and connected device boot-up

January 13, 2015 // By Graham Prophet
Qt 5.4 is the latest version of the cross-platform application and user interface (UI) development framework. It enables the creation of connected devices and applications with native C++ performance, regardless of platform.

Qt 5.4 introduces significant advances for device creation crucial for a variety of industries most notably automotive, STB/DTV, medical and industrial. The addition of a new Chromium-based browser engine, Qt WebEngine, supports HTML5 hybrid development, future-proofing the integration of web technologies. There are improvements to device creation development with several updates and new features, most notably the Qt Quick 2D Renderer plugin, which enables Qt Quick graphics to run without OpenGL allowing Qt Quick to run on low-end devices without a GPU, as well as the Qt Quick Compiler 2.0 reducing device boot-up time and securing against reverse engineering. Reflecting the growth in development of wearable devices and the Internet of Things, a technology preview of Bluetooth Low Energy support is included. Qt 5.4 also includes an update to its Qt Creator IDE to version 3.3, which introduces an all-new Qt Quick Designer and many other productivity enhancing features.

Qt claims a combination of simplicity of development and efficient performance – even on platforms with constrained processing capabilities – with fluid modern UIs. The framework delivers these benefits not only on the initial target platform or device but on all other supported platforms too. Developers can reuse their effort with support on other operating systems or deployment on additional device hardware.

Qt 5.4, says the Qt Company (a subsidiary of Digia) further enhances Qt's ability to bring elegance, functionality and power to the creation of connected devices. Qt’s existing support for creating applications for devices includes C++ libraries, a full embedded tool chain and a pre-built software stack for instant prototyping. Qt 5.4 also introduces a completely new professionally designed “Flat Light” style for Qt Quick Controls that covers traditional and industrial enterprise controls and provides a more polished look-and-feel for application and device UIs.
