Заметки

Each item in a tree view control can have a pair of bitmapped images associated with it. One image is displayed when the item is selected, and the other is displayed when the item is not selected. For example, an item might display an open folder when it is selected and a closed folder when it is not selected.

For more information on image lists, see the CImageList class.
