Detailed Description

TheQDeclarativeScriptString class encapsulates a script and its context.

QDeclarativeScriptString is used to createQObject properties that accept a script "assignment" from QML.

Normally, the following QML would result in a binding being established for thescript property; i.e.script would be assigned the value obtained from runningmyObj.value = Math.max(myValue, 100)

MyType {script:myObj.value=Math.max(myValue,100)}

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

QDeclarativeExpression expr(scriptString.context(), scriptString.script(), scriptStr.scopeObject());expr.value();
