[Qt-interest] What QT version is this?

[Scott Sibley]

Oh. Interesting. I think that's what happened. Here's what I called.

QObject *obj = new QObject();
obj->setProperty(name, engine.newFunction(func),
QScriptValue::PropertyGetter);

I can't find it now, but I'm pretty sure I pulled that from the docs.

At any rate, that opened up a new error.

Evaluator.cpp:26: error: passing 'const QScriptValue' as 'this' argument of
'void QScriptValue::setProperty(const QString&, const QScriptValue&, const
QFlags<QScriptValue::PropertyFlag>&)' discards qualifiers
scons: *** [Evaluator.o] Error 1

void Evaluator::AddFunction(const char *name,
    QScriptValue (*func)(QScriptContext *ctx, QScriptEngine *eng)) {
    QString key = name;
    obj.setProperty(key, engine.newFunction(func),
QScriptValue::PropertyGetter); // line 26
}

I'm not sure what to do here. I can pass setProperty a non-const
QScriptValue fine. Here are the signatures:
/usr/include/QtScript/qscriptvalue.h:184: note: candidates are: void
QScriptValue::setProperty(const QString&, const QScriptValue&, const
QFlags<QScriptValue::PropertyFlag>&)
/usr/include/QtScript/qscriptvalue.h:189: note:                 void
QScriptValue::setProperty(quint32, const QScriptValue&, const
QFlags<QScriptValue::PropertyFlag>&)
/usr/include/QtScript/qscriptvalue.h:194: note:                 void
QScriptValue::setProperty(const QScriptString&, const QScriptValue&, const
QFlags<QScriptValue::PropertyFlag>&)

newFunction returns a const QScriptValue. I'm confused. Why does it except a
non-const QScriptValue, but not the const?
