Question

List the events in developing an event-driven program.

Answer 1

Solution:

The events in developing event driven program.

• The event driven program is a special category of programming paradigm where control of the program execution is determined by a number of events and there will be a set of actions for each event to be performed.
• The events or steps in developing an event driven program are:
  1. Write event handler routines.
     • This event is to write a subroutines or functions that associated with the events or action to be performed on triggering a particular event.
  2. Bind the event handlers to respective events.
     • In first step, the action to be performed on evoking some particular events is defined, but there won’t be any event handler associated with it.
     • In this step, the events and event handler binding is performed.
     • There can be many to many binding, that is, a number of events can be bind to an event handler and vice versa based on program requirements.
  3. Developing the event driven program.
     • All the requirements for an event driven program is available from first two events.
     • Here, he main function of the event driven program will be written and it will determine the actual control of the flow.
