46\class QQmlScriptString-
47\brief The QQmlScriptString class encapsulates a script and its context.-
48\inmodule QtQml-
49-
50QQmlScriptString is used to create QObject properties that accept a script "assignment" from QML.-
51-
52Normally, the following QML would result in a binding being established for the \c script-
53property; i.e. \c script would be assigned the value obtained from running \c {myObj.value = Math.max(myValue, 100)}-
54-
55\qml-
56MyType {-
57 script: myObj.value = Math.max(myValue, 100)-
58}-
59\endqml-
60-
61If instead the property had a type of QQmlScriptString,-
62the script itself -- \e {myObj.value = Math.max(myValue, 100)} -- would be passed to the \c script property-
63and the class could choose how to handle it. Typically, the class will evaluate-
64the script at some later time using a QQmlExpression.-
65-
66\code-
67QQmlExpression expr(scriptString);-
68expr.evaluate();-
