@defclass/title[embedded-toggle-button% snip-wrapper% (alignment<%>)]{
|
|
|
|
A @scheme[check-box%]-like control that a user can toggle between
|
|
checked and unchecked states.

@defconstructor[([images-off (cons/c path-string? path-string?)]

The @scheme[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 @scheme[images-on] argument similarly determines the images
|
|
for then the button is checked.
|
|
|
|
The @scheme[turn-on] and @scheme[turn-off] callbacks are invoked when
|
|
the button changes to checked or unchecked, respectively.
|
|
|
|
The @scheme[state] argument determines whether the button is initially
|
|
checked.}
