Pass by reference in QtScript

[songyu_us]

Does anyone know if I can pass a parameter by reference in QtScript? For example,

var nTimeOut = 0;
app.getTimeOut(nTimeOut);
if (nTimeOut > 0)
{
    ...
}

var nTimeOut = 0;
app.getTimeOut(nTimeOut);
if (nTimeOut > 0)
{
    ...
}

To copy to clipboard, switch view to plain text mode 

here app is an c++ object that I exposed to Qt script environment and I am trying to change the value of nTimeOut in the c++ side and want to catch the changed value from the script side.

Thank you in advance.
