Is there a way to configure a sort of cascading property evaluation/binding ?
For example, think about an RPG character, where one of his stats might be made up of an accumulation of an arbitrary number of values from other properties, even in other objects. For example, the characters 'defense' stat, might be made up of a base defense stat, calculated by the abilities of the character, and then modified by any number of items he has equipped. Is there a way to utilize the property binding of QML to help maintain accurate calculations of these stats between dependencies, as items are equipped, spells temporarily buff stats, etc >From the data here http://doc.qt.nokia.com/4.7-snapshot/propertybinding.html, it looks like one option could be to bind these stats to functions that may calculate them arbitrarily, but it doesn't seem to go into much detail about how the binding works in a situation where you bind a property to a function. Under what conditions will the property bound function be automatically re-evaluated ? What if the function loops over other components or child components to accumulate information? Seems unlikely that a property binding would occur then, and even if it did, what happens when the values change? Thanks
