If UI element icons are set as null, no icons are
displayed.
Note: It is recommended to have transparent background in icon images. When
icon images use transparency, theme graphics are shown through the transparent
parts of an icon. Additionally, icons do not need to be rectangular. In List icons,
the highlighted icon will also show through these transparent parts. Transparency
is available for PNG and GIF images.
