How It Works
This recipe is a simple application that allows you to view images having file formats
such as
.jpg
,
.png
, and
.gif
. Loading an image requires using the mouse to drag-
and-drop a file onto the window area. The application also allows you to resize the
window, which automatically causes the image to scale while maintaining its aspect ra-
tio. After a few images are successfully loaded, you will be able to page through each
image conveniently by clicking the left and right button controls, as shown in

Before the code walk-through, let's discuss the application's variables.
Table 15-1
describes instance variables for this sleek image viewer application.
