implement ability to dynamically change class of script objects
With an object created by QScriptEngine::newObject(), it should
be possible to call QScriptValue::setClass() to dynamically
change the behavior of that object. Similarly, it should be
possible to promote plain script objects to QObject (QVariant)
wrappers by calling the overload of QScriptEngine::newQObject()
(newVariant()) that takes a script object as the first argument.
This commit implements this capability.
The premise is the (internal) QScriptObject class, which inherits
JSC::JSObject. It reimplements all the methods for getting/setting
properties etc. Then there's a level of indirection to facilitate
dynamic change of the class: Each QScriptObject can have a
delegate associated with it that will handle operations on the
object. By default there is no delegate, so the object behaves as
a normal JS object, as you expect. However, once a delegate is set
(e.g., when QScriptValue::setScriptClass() is called),
QScriptObject will give the delegate the chance to handle the
object operation.
In addition to a delegate implementation for QScriptClass-based
objects, there are also delegates for QObject and QVariant
wrappers. These replace the QObjectWrapperObject and
QVariantWrapperObject classes.
