[REBOL] context question
From: kpeters::otaksoft::com at: 31-Aug-2007 15:21
Why does Rebol not complain about 'f2text not having a value in 'show-form2???? It forces
me to use the context to talk to the layout and the 'change-text function which makes
good sense to me. How come it "sees" the "sub-part" 'f2text when it cannot "see" its
parent? Would one of the gurus please shed some light on this for me? As always, thanks
a lot! Kai rebol[] ;------------------------------------------- show-form2: does [ unview
view/new ctx/form2 ; makes good sense ctx/change-text ; makes good sense set-face f2text
"GREEN" ; ?????? ] ;------------------------------------------- form1: center-face layout
[ btn "Show form 2" [ show-form2 ] ] ;------------------------------------------- ctx:
context [ change-text: does [ set-face f2text "BLUE" ] ; form2: center-face layout [
f2text: text "RED" ] ] ;------------------------------------------- view form1 ;----------------
