Hi,
The new behavior is correct. You define the property to be a
getter/setter, which means you can do
var a = ReadFile; // this will call your function
ReadFile = 123; // this will call your function with argument 123
The statement
ReadFile();
will call your property getter, then attempt to call the result of that
call. If your property getter itself doesn't return a function, the
latter call will fail.
Judging from your code snippets it seems you actually want ReadFile to
behave like an ordinary function, not like a property getter/setter. So
just remove the QScriptValue::PropertyGetter |
QScriptValue::PropertySetter argument.

Kent
