Description

The class image-list is used to manage the images displayed by tree-view and list-view.

The initarg :image-sets specifies a list. Each item in the list image-sets may be one of the following:

A pathname or string	This specifies the filename of a file suitable for loading with load-image.
A symbol	The symbol must be a predefined image identifier, or have been registered by means of a call to register-image-translation.
An image object	For example, as returned by load-image.
An image-set object	See image-set for further details. Note that image sets are added in their entirety; it is not possible to use image-locators to extract a single image from an image set.

The images added to the image list are numbered in order, starting from zero. An image-set containing n images contributes n images to the image list, and hence consumes n consecutive integer indices.
