Same idea as effect and effects,
so text and texts. You need to update
both the current TEXT and the TEXTS
facets....
Try these, and click the button:
view layout [b: button "text" [probe b/texts]]
;== ["text"]
view layout [b: button "text" "alt text" [probe b/texts]]
;== ["text" "alt text"]
same? b/text b/texts/1 ;== true
To see how it all works, you must look at the
feel of the button style.
probe b/feel
You can see what happens when you click.
Read carefully, you will see EFFECT and EFFECTS,
TEXT and TEXTS, and COLOR & COLORS mentioned.
It's also useful to see what facets are in a face
object:
print mold first b
and to see what value one of them has:
b/style ;== button
also check the init code of the face:
print mold b/init
