Window Representation

Introduction

In order to use an object, you must be aware of it. A window makes itself known using two types of representations: an icon and/or a frame.

The Icon Representing a Window

An icon is a picture used to identify a program or another type of object on the computer. As such, the small pictures that appear on the computer desktop are called icons. Besides the desktop, there are many other places where you will see icons when using the computer.

There are two entities that mainly need to interact with icons:

* As a person using the computer, icons allow you to familiarize with the various programs that are installed in a computer. Every

application or every category of application has its own icon. This is easily possible because every person who creates an application has the possibility of providing a special icon for that particular application.
* The operating system also has an interior mechanism to identify an icon or a type of icon and associate it with a particular application or a series of applications
of the same type.
Microsoft Windows ships with various icons for its own use. For example, every version of Microsoft Windows ships with a special icon for the My Computer program
. There is also a special icon for Recycle Bin, etc.
The sizes of icons are standardized and they should not have just any random dimensions. For example, the icons on the desktop are 32x32 pixels. Sometimes, the icons display in a 16x16 dimension.
