Hello,
I have the following situation. I have a C++ class (Point) and I
wrapped it inside a JS object. In JS, I do something like:
Point.prototype.testProperty="Hi there!"
var p=new Point(1,2);
for(var i in p)
{
trace("property: "+i);
}
Unfortunately, p doesn't have any property called testProperty.
Similar thing works just fine with 100% JS managed objects:
function Circle(r){
this.radius=r;
this.print=function(){
trace("Radius: "+r);
}
}
Circle.prototype.border="thick";
var c=new Circle(100);
for(var i in c)
{
trace("property: "+i);
}
And the output is:
property: radius
property: print
property: border
Is it possible to alter the prototype of a wrapped C++ object from JS
or not?
Here is the C++ relevant part:
Persistent<FunctionTemplate> _pointFunctionTemplate;
_pointFunctionTemplate =
Persistent<FunctionTemplate>::New(FunctionTemplate::New(pointConstructor));
_pointFunctionTemplate->SetClassName(String::New("Point"));
_pointFunctionTemplate->PrototypeTemplate()->SetInternalFieldCount(1);
global->Set(String::New("Point"), _pointFunctionTemplate);
and the pointConstructor function is this:
Handle<Value> pointConstructor(const Arguments& args) {
Handle<Object> result = _pointFunctionTemplate->PrototypeTemplate()-
>NewInstance();
Point *pPoint = new Point(args[0]->ToNumber()->Uint32Value(), args[1]-
>ToNumber()->Uint32Value());
result->SetInternalField(0, External::New(pPoint));
return result;
}
Thank you very much
