Is there a way to differentiate between bound and unbound properties in C++?

[b.roth]

Hello fellow Qt Quick enthusiasts,

is there any way to figure out if a component's property was set statically or if it receives its values through a binding? I did not find a solution using "QDeclarativeProperty":http://doc.qt.nokia.com/4.7-snapshot/qdeclarativeproperty.html

@property int test: 20 // static assignment
property int test: someObject.someValue // dynamic binding@

Another question related to this is, if there exists a possibility to access QML ids from C++ or if this is technologically impossible.

Greets,
Bernhard
