QtScript: how using typedef enum as slot parameter in QtScript

[JSchmidt]

I want to call a slot of a class by a QtScript. But this slot has a typedef enum as parameter. I cannot figure out, how this will work.

I have something like this:
@
typedef enum
{
A = 0x02
B = 0x03
} MyVersion;

...

class Something : public QObject
{
...
public slot:
void setVersion( MyVersion vNumber);
}
@

Now I want to call that slot 'setVersion' in QtScript like:
@
//QtScript call 1
MyScriptSomething.setVersion( A );
@

or at least:
@
//QtScript call 2
MyScriptSomething.setVersion( 2 );
@

All I ever tried gave me the errors
QtScript call 1: "ReferenceError: Can't find variable: A"
QtScript call 2: "TypeError: Incompatible type of argument(s) in call to setVersion(); candidates were setVersion(MyVersion)"
