+ \title What's New in Qt 4.6
+
+ Qt 4.6 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 comprehensive list of changes between Qt 4.5 and Qt 4.6 is
+ included in the \c changes-4.6.0 file
+ \l{http://qt.nokia.com/developer/changes/changes-4.6.0}{available
+ online}. A \l{Known Issues in %VERSION%}{list of known issues}
+ for this release is also available.
+
+ Changes between this release and the previous release are provided
+ in the \c{changes-%VERSION%} file (also
+ \l{http://qt.nokia.com/developer/changes/changes-%VERSION%}{available online}).
+
+ A list of other Qt 4 features can be found on the \bold{\l{What's
+ New in Qt 4}} page.

+
+ \section1 Animation Framework
+
+ The animation framework helps build highly animated,
+ high-performance GUIs without the hassle of managing complex
+ structures, timers, and easing curves, not to mention the large
+ state graphs that all animated GUIs tend to be full of.
+
+ The framework makes it easy to animate \l{QObject}s, including
+ QWidgets, by allowing Qt properties to be animated. It also allows
+ creating custom animations and interpolation functions. Graphics
+ views are not left out--one can animate \l{QGraphicsWidget}s,
+ which inherits from QObject (and thereby enables properties).
+
+ Animations are controlled using easing curves and can be grouped
+ together. This enables animations of arbitrary complexity.
+
+ The API is easy to grasp with functions such as start(), stop(),
+ pause(), and currentTime(). Here is an image from one of the
+ examples that come with the framework:
+
+ \image whatsnewanimatedtiles.png
+
+ The animation framework also plugs into the new Qt Statemachine by
+ allowing an animation to be played when transitions are triggered.
+ The state machine framework is introduced in 4.6 and is described
+ below.
+
+ \section1 State Machine Framework
+
+ The state machine framework provides a robust state chart
+ implementation based on Harel statecharts and SCXML. Qt's API lets
+ you construct such state graphs and execute them. The key benefits
+ of a state machine are:
+
+ \list
+ \o Simplify complex application semantics.
+ \o Use of states to reduce code bloat.
+ \o Use states to improve maintainability.
+ \o Makes event-driven programming robust and more
+ reusable.
+ \endlist
+
+ It is especially the last item here that makes using a state
+ machine worthwhile. A key characteristic of event-driven systems
+ (such as Qt applications) is that behavior often depends not only
+ on the last or current event, but also the events that preceded
+ it. With statecharts, this information is easy to express.
+
+ The framework fits neatly into Qt by allowing transitions to
+ trigger on signals and \l{QEvent}s. By inserting animations into
+ the state machine, it is also easier to use the framework for
+ animating GUIs, for instance.
+
+ \section1 Multi-touch & Gestures
+
+ The new multi-touch and gestures support enables user interaction
+ with more than one finger, and combines sequential touch inputs to
+ a 'gesture'.
+
+ \image gestures.png
+
+ The main benefits of this new functionality are:
+
+ \list
+ \o Allow users to interact with applications in better ways.
+ \o Simplify finger-based interaction with UI components.
+ \o Allowing common basic gestures and multi-touch
+ gestures.
+ \o Enable extensibility.
+ \endlist
+
+ \section1 DOM access API
+
+ Web pages and XML both have very complex document object models.
+ The W3C selector API provides a very simple way to access and
+ manipulate such structures. This API makes it intuitive to access
+ DOM, helps reuse CSS selector knowledge, and gives little
+ maintenance or footprint overhead.
+
+ \code
+ QWebElement document = frame->documentElement();
+ QList<QWebElement> allSpans = document.findAll("span");
+ QList<QWebElement> introSpans = document.findAll("p.intro span");
+ \endcode
+
+ \section1 Qt3D enablers
+
+ As more of Qt, and more of the applications built on Qt go 3D,
+ API's should be provided to simplify this. Mainly, the new API
+ aims to make it more easy to create 3D applications with OpenGL.
+ It will also unify the Qt OpenGL codebase, and enable
+ cross-platform 3D codebase.
+
+ The main features of the Qt3D enablers are currently: Math
+ primitives for matrix multiplication, vectors, quaternions
+ (client-side), and API for vertex and fragment shaders, GLSL/ES.
+ Future research will, among other things include stencils,
+scissors, vertex buffers and arrays, texture manipulation, and
+ geometry shaders.
+
+ \section1 Performance Optimizations
+
+ As always, Qt continuously strive to optimize its performance.
+ For this release, we have:
+
+ \list
+ \o Rewritten the QGraphicsView rendering algorithm.
+ \o Made QPixmapCache support efficient Key datastructure.
+ \o Reduced overhead in QNetworkAccessManager.
+ \o Added the QContiguousCache class, which provides efficient caching of
+ contiguous data.
+ \o Removed Win9x support.
+ \endlist
+
+ \section1 Multimedia Audio Services
+
+ Qt 4.6 comes with new classes for handling audio. These classes
+ provide low-level access to the system's audio system. By
+ specifying the audio format (QAudioFormat) and supplying audio
+ data through a QIODevice, you get direct access to the
+ functionality of the sound device. The API also comes with
+ functions to query audio devices for which audio formats they
+ support.

\section1 Improved Network Proxy Support
Qt's networking classes have been updated with
- \l{Network Programming#Support for Network Proxies}{improved proxy support}.
+ \l{QtNetwork Module#Support for Network Proxies}{improved proxy support}.
This includes improved integration with system proxy settings and the added
ability to handle non-trivial proxy cases.
