/**
* A Icon List Widget displays a list of items, each with a text and
* optional icon.  Icon List can display its items in essentially three
* different ways; in big-icon mode, the bigger of the two icons is used
* for each item, and the text is placed underneath the icon. In mini-
* icon mode, the icons are listed in rows and columns, with the smaller
* icon preceding the text.  Finally, in detail mode the icons are listed
* in a single column, and all fields of the text are shown under a
* header control with one button for each subfield.
* When an item's selected state changes, the icon list sends
* a SEL_SELECTED or SEL_DESELECTED message.  A change of the current
* item is signified by the SEL_CHANGED message.
* The icon list sends SEL_COMMAND messages when the user clicks on an item,
* and SEL_CLICKED, SEL_DOUBLECLICKED, and SEL_TRIPLECLICKED when the user
* clicks once, twice, or thrice, respectively.
* When items are added, replaced, or removed, the icon list sends messages
* of the type SEL_INSERTED, SEL_REPLACED, or SEL_DELETED.
* In each of these cases, the index to the item, if any, is passed in the
* 3rd argument of the message.
