Spring4D TPropertyChangedEventArgs example

[Dave Novo 51]

Hello, 

 

Is there an example of how TPropertyChangedEventArgs and associated infrastructure is supposed to be used?

 

I am hoping there is some magic somehow where I can get a notification that a property changed on a class, without having to modify the source of that class to throw an event. Not sure how this would be done, magic code hooks, VMT hijacking or some other craziness. But when I see some of the magic in Spring4D, I can believe that almost anything is possible 🙂

There is no magic, you implement INotifyPropertyChanged and raise events in setters.
