You appear to have stumbled on one of those gray areas that is an exception
(or possibly a "bug" or an under appreciated "feature"). I do not recall if
there is a way to get *to* this data. Here is another work around to
defining the button text in the layout and still being able to get at it.
Hopefully a wizard can elucidate that real nature of this beast.
view/new lay: layout [
b: button with [text: "test"]
button "change above" [
lay/pane/1/text: "dither"
show b
]
button "change top" [
; the following is another way to change the info
b/text: "yon"
show b
]
]
lay/pane/1/text: "hither"
show b
