Understanding Events and Event-Driven Programming
As I explained in Chapter 7, “Working with Objects,” events are a mechanism, usually associated with an object, for responding to actions such as the user clicking a button or a page being loaded. When the action occurs, an event handler is triggered (this is also called firing an event). This is the opportunity for you, the programmer, to place code that the event handler invokes.
