In computer programming, an event handler is an asynchronous callback subroutine that handles inputs received in a program. Each event is a Piece of application-level information from the underling framework, typically the GUI toolkit. GUI events include key presses, mouse movement, action selections and timers expiring. Event handlers are a central concept in event-driven programming.
