Event Driven Programming

Traditional programming:

• The program’s main algorithm governs the flow of control  throughout the program

• The general model:

“do step A, then do step B, then do C or D, then…”

Event-driven programming:

• The program waits for the user to do something, processes that event, then waits for the user again.

• The general model:
  loop
  
  get user event
  process user event
  do something that responds
  to that event
  endloop
