notify()

void QPropertyObserverPointer::notify ( QUntypedPropertyData *  propertyDataPtr )

inline

Walks through the list of property observers, and calls any ChangeHandler found there. It doesn't do anything with bindings, which are only handled in QPropertyBindingPrivate::evaluateRecursive.

The same as setBindingToNotify, but assumes that the tag is already correct.

Like unlink, but does not handle ObserverIsAlias. Must only be called in places where we know that we are not dealing with such an observer.
