'''QtScript''' is a scripting engine that has been part of the [[Qt (framework)|Qt]] [[cross-platform]] [[application framework]] since version 4.3.0.

The [[scripting language]] is based on the [[ECMAScript]] standard with a few extensions, such as QObject-style signal and slot connections.<ref>{{cite web |url=http://doc.trolltech.com/4.6/scripting.html#ecmascript-compatibility |title=Making Applications Scriptable: ECMAScript Compatibility |work=Qt 4.6 |publisher=Nokia |accessdateaccess-date=5 September 2011 |archive-url=https://web.archive.org/web/20100928053842/http://doc.trolltech.com/4.6/scripting.html#ecmascript-compatibility |archive-date=2010-09-28 |url-status=dead }}</ref> The library contains the engine, and a [[C++]] API for evaluating QtScript code and exposing custom QObject-derived C++ classes to QtScript.

The QtScript Binding Generator<ref>[http://qt.gitorious.org/qt-labs/qtscriptgenerator QtScript Generator] {{webarchive|url=https://web.archive.org/web/20111228033225/http://qt.gitorious.org/qt-labs/qtscriptgenerator |date=2011-12-28 }}</ref> provides bindings for the Qt API to access directly from ECMAScript.{{clarify|post-text=update needed?|date=September 2011}} QtScript and the binding generator are used for [[Amarok (software)|Amarok]] 2's scripting system.

The current (as of Qt 4.7) implementation uses [[JavaScriptCore]] and will not be further developed. The module is deprecated as of Qt 5.5.<ref>{{cite web |url=http://wiki.qt.io/New-Features-in-Qt-5.5#Deprecated_Functionality | title=New Features in Qt 5.5 | publisher=Qt Company |accessdateaccess-date=15 April 2015}}</ref>

== Qt Script for Applications (QSA) ==

An earlier and unrelated scripting engine, called '''Qt Script for Applications''' (QSA), was shipped by Trolltech as a separate Qt-based library, dual-licensed under [[GNU General Public License|GPL]] and a commercial license.

With the release of QtScript, QSA has been deprecated and reached its end of life in 2008.<ref>{{cite web |last=Hansen |first=Kent |date=5 January 2007 |url=http://blog.qt.digia.com/blog/2007/01/05/say-hello-to-qtscript/ |title=Say hello to QtScript! |work=Qt Labs: Developer Blogs |publisher=Nokia |accessdateaccess-date=23 November 2013 |url-status=dead |archiveurlarchive-url=https://www.webcitation.org/6HfSMamF0?url=http://blog.qt.digia.com/blog/2007/01/05/say-hello-to-qtscript/ |archivedatearchive-date=26 June 2013 }}</ref>
