Qt Script for Applications
Encyclopedia
QtScript is a scripting engine that has been part of the 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. 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 provides bindings for the Qt API to access directly from ECMAScript. QtScript and the binding generator are used for Amarok 2's scripting system.
The current (as of Qt 4.7) implementation uses JavaScriptCore.
and a commercial license.
With the release of QtScript, QSA has been deprecated and reached its end of life in 2008.
