A @racket[switchable-button%] control displays
|
|
and icon and a string label. It toggles between
|
|
display of just the icon and a display with the
|
|
label and the icon side-by-side.

The @racket[callback] is called when the button
|
|
is pressed. The @racket[string] and @racket[bitmap] are
|
|
used as discussed above.
|
|
|
|
If @racket[alternate-bitmap] is supplied, then it is used
|
|
when the button is switched to the view that just shows the bitmap.
|
|
If it is not supplied, both modes show the same bitmap.
|
|
|
|
If the @racket[vertical-tight?] argument is @racket[#t], then the button takes up
|
|
as little as possible vertical space.
