PySide.QtDeclarative.QDeclarativeScriptString class encapsulates a script and its context.
PySide.QtDeclarative.QDeclarativeScriptString is used to create PySide.QtCore.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)
MyType {
script: myObj.value = Math.max(myValue, 100)
}
If instead the property had a type of PySide.QtDeclarative.QDeclarativeScriptString , 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 PySide.QtDeclarative.QDeclarativeExpression .
QDeclarativeExpression expr(scriptString.context(), scriptString.script(), scriptStr.scopeObject());
expr.value();
