Detailed Description

QQmlScriptString 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 script property; i.e. script would be assigned the value obtained from running myObj.value = Math.max(myValue, 100)

If instead the property had a type of QQmlScriptString , the script itself – myObj.value = Math.max(myValue, 100) – would be passed to the script property and the class could choose how to handle it. Typically, the class will evaluate the script at some later time using a QQmlExpression .

QQmlExpression expr(scriptString);
expr.evaluate();
