QT Scripting - Native Functions

[gabon]

I am trying to follow the help example. So I created a method in the class which is handling the script engine:

// .h
QScriptValue random(QScriptContext *context, QScriptEngine *engine);

// .h
QScriptValue random(QScriptContext *context, QScriptEngine *engine);

To copy to clipboard, switch view to plain text mode 

Then I implemented it (it's just a test):

// .cpp
QScriptValue MyClass::random(QScriptContext *context, QScriptEngine *engine)
{
    QScriptValue a = context->argument(0);
    return a.toNumber();
}

// .cpp
QScriptValue MyClass::random(QScriptContext *context, QScriptEngine *engine)
{
    QScriptValue a = context->argument(0);
    return a.toNumber();
}

To copy to clipboard, switch view to plain text mode 

When I try to register it:

QScriptValue fun = engine.newFunction(random);
engine.globalObject().setProperty("random", fun);

QScriptValue fun = engine.newFunction(random);
engine.globalObject().setProperty("random", fun);

To copy to clipboard, switch view to plain text mode 

I get: /.../../helloscript/myclass.cpp:14: error: no matching function for call to 'QScriptEngine::newFunction(<unresolved overloaded function type>)'

Any idea what's wrong? The only difference I can see from the example is that in my case the function is a class method.

Is it because "global functions" have to be static?


Thanks, chr

Your "random" is not a function but a class member method. Make it a standalone function or make it static.
