Qt 4.7 provides many improvements and enhancements over the previous releases in the Qt 4 series. This document covers the most important features in this release, separated by category.
A list of other Qt 4 features can be found on the What's New in Qt 4 page.
Qt 4.7 introduces Qt Quick, the Qt UI Creation Kit. that enables the creation of dynamic user interfaces, easier and more effective than possible with existing UI technologies. This UI Creation Kit consists of three technologies:
Bearer Management controls the connectivity state of the system. The new Bearer Management API in the QtNetwork module allows the application to identify whether the system is online and how many interfaces there are, as well as start and stop interfaces, or roam transparently between access points.
QNetworkAccessManager uses this API for HTTP level roaming.
The Multimedia API provides media playback and playlist support for Qt Applications. Play music and movies through a single interface with selectable output for movies to widgets or graphics view.
Multimedia support for Quick is also available with the new multimedia declarative elements.
