Detailed Description

The QScriptString class acts as a handle to "interned" strings in a QScriptEngine.

QScriptString can be used to achieve faster (repeated) property getting/setting, and comparison of property names, of script objects.

To get a QScriptString representation of a string, pass the string to QScriptEngine::toStringHandle(). The typical usage pattern is to register one or more pre-defined strings when setting up your script environment, then subsequently use the relevant QScriptString as argument to e.g. QScriptValue::property().

Call the toString() function to obtain the string that a QScriptString represents.
