QtScript: accessing methods of QObject* subclass from script

[profoX]

I am very new to QtScript and I have used QScriptEngine::evaluate() to evaluate this script:

function render(node) {
    var stream = node.getStream();
    print("typeof stream "+typeof stream + "," + stream);
    var test = stream.test();
}

function render(node) {
    var stream = node.getStream();
    print("typeof stream "+typeof stream + "," + stream);
    var test = stream.test();
}

To copy to clipboard, switch view to plain text mode 

Now, I have used Q_DECLARE_METATYPE(Stream*)
and node.getStream() returns Stream*

In the script the output is as follows:

typeof stream object,QVariant(Stream*)

typeof stream object,QVariant(Stream*)

To copy to clipboard, switch view to plain text mode 

Stream has a public slot with testmethod() returning an int:

public slots:
    int testmethod() {return 8;}

public slots:
    int testmethod() {return 8;}

To copy to clipboard, switch view to plain text mode 

But then I get the following TypeError in the script when I try to access the testmethod() method of Stream

TypeError: Result of expression 'stream.testmethod' [undefined] is not a function.

I am obviously not doing this right? Can someone help me in the right direction to make this work?

Many thanks.
