[REBOL] Little questions, big answers...
From: dness:home at: 4-Sep-2001 15:48
Although I have considerable experience across a wide range of programming
languages, REBOL is different enough that learning it is a challenge. So far
it has been a very productive and worthwhile challenge, but `hard' nonetheless.
I have a few small fragments of code that
(a) work; and
(b) I don't understand at all (having cribbed them from some piece
or other of working code). I have the feeling that if I could gradually
understand them, I'd learn something about REBOL.
Here's an example. I have
dex-pane1: layout/offset [
origin 0 space 2x0 across
label right "IP Address" 200x24 bold middle font-size 16 return
IP-1: fld right return
IP-2: fld right return
IP-3: fld right return
IP-4: fld right return
IP-5: fld right return
which produces a panel in a display of IP addresses and Machine names.
What I am unclear about is at least:
(1) what _are_ `IP-1' ... here inside the layout. Are they `objects' created
by this declaration?
(2) Is there some way I can `dump' `IP-n' to take a look at what they are;
(3) My display obviously is `wired' to display 5 addresses. How would one normally
Although detailed programming advice is always welcome, I am more looking for (a few)
words about what is really `going on' in something like this `layout' declaration, if
that can be answered in less than a long epistle.
