See http://doc.trolltech.com/latest/qscriptengine.html#newFunction

This provides functionality similar to JSObjectMakeFunctionWithCallback() and JSObjectMakeConstructor() in the JSC C API.
Implementing this feature also requires implementing the QScriptContext class (see http://doc.trolltech.com/latest/qscriptcontext.html), which provides the arguments, callee and this-object for a particular invocation of the function.

In QtScript, the same type of callback is used for both normal functions and constructors; QScriptContext::isCalledAsConstructor() can be used to query whether the function was called as a constructor (e.g. as operand to "new").
