# Qt Script C++ Classes

The Qt Script module provides classes for making Qt applications scriptable. More...

This module was introduced in Qt 4.3.

## Detailed Description

The Qt Script module only provides core scripting facilities; the Qt Script Tools module provides additional Qt Script-related components that application developers may find useful.

Warning: This module is not actively developed. It is provided for backwards compatibility with Qt 4 only. For new code, use QJSEngine and related classes in the Qt QML module instead.

To include the definitions of the module's classes, use the following directive:

     #include <QtScript>

To link against the module, add this line to your qmake `.pro` file:

     QT += script

For detailed information on how to make your application scriptable with Qt Script, see Making Applications Scriptable.

### License Information

Qt Commercial Edition licensees that wish to distribute applications that use the Qt Script module need to be aware of their obligations under the GNU Library General Public License (LGPL).

Developers using the Open Source Edition can choose to redistribute the module under the appropriate version of the GNU LGPL.

Commercial customers that do not want to depend on LGPL code can consider using the QJSEngine and QJSValue classes in the Qt Qml module. These classes offer a similar but more narrow scripting API that is sufficient for most use cases and is not dependent on LGPL code.
