If you want to bind an object to other properties you must first construct the object using ordinary methods with dummy values and then you can access its properties to bind its values.

It would be nice if you could do this with constructors. One problem with doing it with constructors is that many objects would likely have a mix of bound and unbound attributes and there is no "autoboxing" for JavaFX bindings that could be called upon to avoid having to have an explosion of overloaded constructors. Should we at least consider a single "all attributes as properties" constructor for each or most of the core objects?

On the other hand, the builders could easily offer a mix by having single overloads of the various property initializers that took the appropriate form of "FooProperty" and which would execute a bind on that property for the indicated attribute.
