\class QDeclarativeScriptString
\since 4.7
\brief The QDeclarativeScriptString class encapsulates a script and its context.
QDeclarativeScriptString is used to create QObject properties that accept a script "assignment" from QML.
Normally, the following QML would result in a binding being established for the \c script
property; i.e. \c script would be assigned the value obtained from running \c {myObj.value = Math.max(myValue, 100)}
\qml
MyType {
script: myObj.value = Math.max(myValue, 100)
}
\endqml
If instead the property had a type of QDeclarativeScriptString,
the script itself -- \e {myObj.value = Math.max(myValue, 100)} -- would be passed to the \c script property
and the class could choose how to handle it. Typically, the class will evaluate
the script at some later time using a QDeclarativeExpression.
\code
QDeclarativeExpression expr(scriptString.context(), scriptString.script(), scriptStr.scopeObject());
expr.value();
\endcode
\sa QDeclarativeExpression
