Program Plan Intro

Event:

• It is nothing but an action that is performed during the runtime of the program.
• Some of the events that are done during the program execution are clicking buttons, dropdown box, etc.
• When the programmer or user clicks a button, an event occurs.
• At the time of occurrence of an event, an event object is created which contains data about the event.
• The control that creates the event object is called as event source.

Example: Button clicking.
