Introduction

PFObserver.h supports observing changes to UI elements in running applications in real time as changes occur.

Discussion

The accessibility API implements the concept of an "observer," an object based on Core Foundation's CFTypeRef class that registers to observe a user interface element on the screen in a running application and issues accessibility notifications when changes occur. PFObserver.h implements this same concept in its PFObserver class.
