Detailed Description

A widget that shows one of two icons depending on its state.

This is a utility class that simply manages two images, only one of which is shown at a single time, which reflects the current 'state'.

The widget may react to click events, by changing state.

CSS

This widget does not provide styling, and can be styled using inline or external CSS as appropriate. The image may be styled via the <img> elements.
