Each item within the dojox/widget/FisheyeList should be an instance of

dojox/widget/FisheyeListItem. This widget describes the nature of the item to be

shown. Some of its more important properties include:

• iconSrc – The URL for the image to be displayed.

• label – The label to be shown when the icon is over the image.

• on – The Dojo on event handler used to detect when the item is selected.

Programatically, FisheyeListItems are added to the FisheyeList via its addChild() method.

Experience seems to show that before adding the FisheyeListItem to the FisheyeList, a property on

it called "parent" needs to be set to the FisheyeList widget that contains it. This appears to be

necessary when programatically creating the FisheyeList but not when using the HTML declaration

format.

Additional CSS is required for the FisheyeList to function. This CSS can be found within the Dojo

distribution at:

<Root>/dojox/widget/FisheyeList/FisheyeList.css

If one wishes the FishEyeList to be centered, consider adding the style:

.dojoxFisheyeListBar {
