[REBOL] Re: Examining the layout object
From: carl:cybercraft at: 1-Jul-2002 18:16
Hi again,
Just realised that it's the text-list that's causing the error.
Replacing the text-lists with areas in the much bigger layout I'd
been having the problems with allowed the script to look all through
it.
So, I've narrowed the error down to 'face being a function sometimes,
but while this...
print type? :face
gets round it for a word, I don't know how to do that for a function
in an object. ie, this doesn't work......
print type? :face/pane
pane still being evaluated.
So, what's the solution to that?
Carl.
