Qt, the leading cross-platform
application and user interface (UI) development framework is now
available under version Qt 5.3. With Qt, developers can easily develop
cross-platform applications and simply reuse code to target all the
major desktop, embedded and mobile platforms. Qt 5.3 packs in numerous
new features and improvements that enables the simple and effortless
development of applications and connected devices that run anywhere on
any device, on any operating system making the end users' life easier.
To lower the barrier of entry for application development, Digia is also
introducing a monthly subscription plan for Qt Enterprise.
Building on the success of Qt 5.2, which has been downloaded more than 1
million times since December 2013, Qt 5.3 brings enhanced quality across
all platforms with improved documentation and new coding examples
delivering an improved user experience. In addition, the Qt for Windows
Runtime port has now reached the supported Beta state further
strengthening Qt's cross-platform story of defragmenting multi-platform
mobile development. Qt for WinRT allows Qt developers reach a portfolio
of millions of devices including Windows 8 PCs and tablets, applications
using the Modern UI, also for WinRT tablets on ARM chips such as the
Microsoft Surface and Windows Phone devices.
Qt 5.3 boasts several improvements on desktop application development
easing the migration path for existing users to Qt 5. The introduction
of QQuickWidget, which is designed to simplify the migration of larger
Qt Widget-based applicatons to Qt 5, allows for hybrid development with
both, C++ Qt Widgets and Qt Quick UI technology, in one application.
This enables designers and developers to save time using the best of
both UI technologies together without sacrificing the ease and
functionality of the other. The Qt Quick Controls have also received new
updates which include calendar control, native dialogs and styling for
the menu bar as well as several new Qt Quick Enterprise controls for
On the API side, the new Qt Positioning API provides GPS support for
both Android and iOS, while the Qt Bluetooth API now provides direct
support for Android. Qt Enterprise mobile application customers will
also benefit from the new Qt Purchasing API that provides a
simple-to-use, cross-platform Qt API for in-app purchasing from Android
Google Play and iOS App Store. In the future, this will be extended to
WinRT (Windows Store / Windows Phone Store) and desktop marketplaces
such as the Mac OS X store.
Qt 5.3 also announces a new Qt WebSockets API and new Managed WebSockets
backend service in the Qt Cloud Services portfolio that enables
cloud-connected applications and devices to communicate bi-directionally
in real-time. In addition, the Managed WebSockets solution enables any
number of client-server communications so that one-to-many communication
channels, including chat and notifications, can be implemented.
Qt 5.3 introduces a first look at a new professional build tool under
the Qt Enterprise offering, Qt Quick Compiler, which allows you to
compile QML files into the application. The compiler ensures IP
protection of the QML source and improves load time and performance by
pre-parsing the QML files. With compiled Qt Quick, application start up
is up to 90% faster than before. Qt Quick Compiler delivers significant
run-time performance improvements on platforms such as iOS.
Qt Enterprise 5.3 also introduces primary support from Digia for QNX®
Neutrino® 6.6 with pre-built Qt Enterprise binaries that enable
intuitive and attractive UIs for the QNX Car Automotive platforms and
also the healthcare, industrial automation, and in-flight entertainment
