  state : (symbols 'on 'off) = 'on

The images-off argument is a pair filenames to be load as the button-label image, where the first is the image for when the button is at rest, and the second is the image for the button while its pressed – in both cases when the button is not checked by the user. The images-on argument similarly determines the images for then the button is checked.

The turn-on and turn-off callbacks are invoked when the button changes to checked or unchecked, respectively.

The state argument determines whether the button is initially checked.
