Detailed Description¶
QQmlScriptString
is used to createQObject
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 runningmyObj.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 thescript
property and the class could choose how to handle it. Typically, the class will evaluate the script at some later time using aQQmlExpression
.QQmlExpression expr(scriptString); expr.evaluate();See also
