@defproc[(snip-width [snip (is-a?/c snip%)]) real?]{
The width of a snip in the parent pasteboard.}
@defproc[(snip-height [snip (is-a?/c snip%)]) real?]{
The height of a snip in the parent pasteboard.}
@defproc[(snip-min-width [snip (is-a?/c snip%)]) real?]{
The minimum width of the snip}
@defproc[(snip-min-height [snip (is-a?/c snip%)]) real?]{
The minimum height of the snip.}
@defproc[(snip-parent [snip (is-a?/c snip%)]) (is-a?/c pasteboard%)]{
The pasteboard that contains the snip.}
@defproc[(fold-snip [f ((is-a?/c snip%) any/c . -> . any/c)]
[init-acc any/c]
[snip (is-a?/c snip%)])
any/c]{
Applies @racket[f] to all snips in the parent of @racket[snip],
starting with @racket[snip].}
@defproc[(for-each-snip [f ((is-a?/c snip%) . -> . any/c)]
[first-snip (is-a?/c snip%)]
[more list?] ...)
void?]{
Applies the function to each snip in the parent of
@racket[first-snip], starting with @racket[first-snip]. If
@racket[more] lists are supplied, they are used for extra arguments to
@racket[f], just like extra lists provided to @racket[for-each].}
@defproc[(map-snip [f ((is-a?/c snip%) . -> . any/c)]
[first-snip (is-a?/c snip%)]
[more list?] ...)
void?]{
Applies the function to each snip in the parent of
@racket[first-snip], starting with @racket[first-snip], and
accumulates the results into a list. If @racket[more] lists are
supplied, they are used for extra arguments to @racket[f], just like
extra lists provided to @racket[map].}
@defproc[(stretchable-width? [snip (is-a?/c snip%)]) boolean?]{
True if the snip can be resized in the X dimension.}
@defproc[(stretchable-height? [snip (is-a?/c snip%)]) boolean?]{
True if the snip can be resized in the Y dimension.}
