Developing an Event-Driven Application

Developing an Event-Driven Application



Creating wireframes
A wireframe is a picture or sketch of a screen the user will see when running a program.
A wireframe, also called a page schematic or screen blueprint , is a visual guide that helps
developers and their user clients decide on the basic features of an interactive program or
Web site. Wireframes can be pencil sketches or they can be produced by software
applications. Typically, they do not contain graphics or show the final font styles that will
be used; instead, they focus on the functionality of an application.

Creating storyboards
A storyboard contains a series of wireframes that represent a user’s experience with proposed
software. Filmmakers have long used storyboards to illustrate key moments in the plots they are
developing; similarly, GUI storyboards represent “snapshot” views of the screens the user will
encounter during the run of a program.

Defining the objects
An event-driven program may contain dozens or even hundreds of objects. To keep track of
them, programmers often use an object dictionary. An object dictionary is a list of the objects
used in a program, the screens where the objects are used, and any associated code (script).

Defining the connections between the screens the user will see
The insurance premium program is small, but with
larger programs you may need to draw connections
between the screens to show how they interact. An
interactivity diagram shows the relationship between
screens in an interactive GUI program.

storyboard represents a diagram of the logic used in an interactive program?

NO. storyboard represents a picture or sketch of the series of screens the user will see when running a program. Surprised

the important GUI design principle is to always remember that any GUI is only an interface

In computer programming, event-driven programming is a programming paradigm in which the flow of the program is determined by events such as user actions (mouse clicks, key presses), sensor outputs, or messages from other programs/threads.

Consider several general design principles when you create a program that will use a GUI:

The interface should be natural and predictable.
The interface should be attractive, easy to read, and nondistracting.
To some extent, it’s helpful if the user can customize your applications.
The program should be forgiving.
The GUI is only a means to an end.
