Detailed Description

QBindingStorage acts as a storage for property binding related data in QObject. Any property in a QObject can be made bindable by using the Q_OBJECT_BINDABLE_PROPERTY macro to declare it. A setter and a getter for the property and a declaration using Q_PROPERTY have to be made as usual. Binding related data will automatically be stored within the QBindingStorage inside the QObject.
