Please urgently need help rebol/view simple gui

Dear Rebol Expert,
I'm sorry, I'm a newbie and not proficiently good in programming. I'm doing
my school project using Rebol/core software. The machine will pan and tilt
by adjusting 'panoffset' and 'tiltoffset' values below. My problem is how
can I possible run the rebol and then 'show pop up' and adjust the values at
the 'field of text' and confirm with 'ok' button. Could someone please help
me to fix the problem or show me the way to do it. Below is the script;
make integer! n: 0
comment {change these values}
make decimal! panoffset: 0.0
make decimal! tiltoffset: 0.0
Thanks in advanced for the help and very much appreciated.

Hi,
you would need to use REBOL/View instead of REBOL/Core to be able to pop up
a window, REBOL/Core has no GFX support. Also one comment to your script.
You're probably trying to declare that N should be integer! and PANOFFSET
decimal! but that's not needed in REBOL. You can write your script as:
n: 0
comment {change these values}
panoffset: 0.0
tiltoffset: 0.0
In REBOL/core you can use ASK or INPUT
panoffset: to decimal! ask "Enter value for panoffset:"
(beacuse ASK returns string! you have to convert it to decimal!)
Bye,
REBolek

Hi,
Thanks so much for the comment, I'll try to fix it immediately. In
REBOL/View, what function should I use to be able to pop up the window and
to adjust "panoffset" and "tiltoffset". Could someone please help me with
the sample script or a REBOL/view tutorial/doc to look into it because I'm
really in a tight schedule right now.
Regards,
Akram

Any problem in computer science can be solved with another layer of
indirection. But that usually will create another problem.

Hi Akram, try this:
pan-offset: 0.0
tilt-offset: 0.0
refresh: does [
print ["pan:" pan-offset "tilt:" tilt-offset]
]
control-window: center-face layout [
style hscroller scroller 200x20
across
label "pan" hscroller [pan-offset: face/data refresh] with [data:
pan-offset]
return
label "tilt" hscroller [tilt-offset: face/data refresh] with [data:
tilt-offset]
]
view/new control-window
do-events
The scroller/data is from 0.0 to 1.0 only, so if your pan and tilt values
range
outside these bounds, you will need to do map those values, eg:
pan-offset: face/data * 2
etc.
Anton.
