Detailed Description

The class Object does provide us scripting objects like class instances to the C++ world.

This class implements reference counting for shared objects. So, no need to take care of freeing objects.

Sample that does use the Object functionality to pass a Javascript classinstance to C++ code which then calls a method the classinstance provides.

class MyObject : public QObject
{
    public Q_SLOTS:
        QVariant myFunction(Kross::Object::Ptr obj) {
            QVariantList args;
            return obj->callMethod("myMethod", args);
        }
};

function MyClass(result) {
    this.myMethod = function() {
        return result;
    }
}
var myclass = new MyClass("my string");
var r = MyObject.myFunction(myclass);
print(r); // prints "my string"

Member Function Documentation

callMethod()

QVariant Object::callMethod ( const QString &  name, const QVariantList &  args = QVariantList()  )

virtual

Pass a call to the object and evaluated it.

Parameters

name	Each call has a name that says what should be called.
args	The optional list of arguments passed to the call.

Returns

The call-result as QVariant.

Definition at line 49 of file object.cpp.

methodNames()

virtual

Return a list of supported callable objects.

Returns

List of supported calls.

virtual

used virtual hook to easier the job to keep binary compatibility.
