constructor
(new toggle-button-snip% [images-off images-off] [images-on images-on] [turn-on turn-on] [turn-off turn-off] [ [state state]]) → (is-a?/c toggle-button-snip%) images-off : (cons/c path-string? path-string?) images-on : (cons/c path-string? path-string?) turn-on : ((is-a?/c toggle-button-snip%) (is-a?/c event%) . -> . void?) turn-off : ((is-a?/c toggle-button-snip%) (is-a?/c event%) . -> . void?) 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—
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.
