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 */ /*!
