Detailed Description

The UntypedProxyProperty class is a property used in Behavior to handle bindable properties.

Whenever a bindable property with a Behavior gets a request for its bindable interface, we instead return the bindable interface of the UntypedProxyProperty. This causes all reads and writes to be intercepted to use m_storage instead; moreover, any installed binding will also use m_storage as the property data for the binding.

The BehaviorPrivate acts as an observer, listening to changes of the proxy property. If those occur, QQuickBehavior::write is called with the new value, which will then adjust the actual property (playing animations if necessary).

Warning

The interception mechanism works only via the metaobject system, just like it is the case with non-binadble properties and writes. Bypassing the metaobject system can thus lead to inconsistent results; it is however currently safe, as we do not publically expose the classes, and the code in Quick plays nicely.
