I would assume that he meant the button for
demo purposes only. (?)
I would modify the field (perhaps making a style,
if you want multiple fields reacting this way),
adding a facet named like: face/focus-action,
then modify the focus function to look for that
and do it if there is some code there.
(Actually, code should be written the other way
around, but that is the order of execution, anyway.)
; modfiy the global focus function
print mold head insert find/tail second :focus [[hilight-all face]] bind [
;print [face/offset face/text face/size]
if all [in face 'focus-action block? face/focus-action][
;print "do focus-action"
do face/focus-action
]
] fourth second :focus ; (pick out a local word 'face in the func body)
; test with special field
view layout [
field "regular field"
f: field "special" with [focus-action: [print "hello"]]
]
Bindology took some experimenting... :)
Tested OK on Rebol/View 1.2.10, 1.2.8, 1.2.5 and 1.2.1.
