Problem with negative offset of layout
[1/7] from: bzr:francenet at: 23-Dec-2001 18:28
Hi,
It seems that REBOL has problem scrolling layout by a negative offset.
Here is an example which does not work, at least on my machine under
Linux.
When the horizontal or vertical offset is less than -20, the layout
is uncorrectly shifted off by one pixel.
Could you tell me whether you have the same problem? Or whether there
is something wrong in my code?
Thanks in advance.
----------------------------------------------------------------------------
REBOL [ ]
grid-layout: layout [
origin 0x0
space 0x0
box 201x201 white effect [ grid 20x20 ]
]
grid-layout/offset: 0x0
main-layout: layout [
grid-container: box 201x201 with [pane: grid-layout]
grid-offset: label 200x24 ""
across
pad 60
button "up" [
grid-layout/offset/y: grid-layout/offset/y - 20
grid-offset/text: grid-layout/offset
show grid-offset
show grid-container
]
return
button "left" [
grid-layout/offset/x: grid-layout/offset/x - 20
grid-offset/text: grid-layout/offset
show grid-offset
show grid-container
]
button "right" [
grid-layout/offset/x: grid-layout/offset/x + 20
grid-offset/text: grid-layout/offset
show grid-offset
show grid-container
]
return
pad 60
button "down" [
grid-layout/offset/y: grid-layout/offset/y + 20
grid-offset/text: grid-layout/offset
show grid-offset
show grid-container
]
]

There does not appear to be anything wrong with your code as far as I can
tell, and yes I can see the effect on my machine (Windows NT4).

Same here on Win2k.
You should probably send to feedback and we'll see
what they say.

REBOL/Command/View [Win98se] => works OK here.
Is it possible linux fil endings are throwing your script off?
Anyway, thanks for showing me very cool view scrolling..

But does not work for Rebol/View [Win98]. Two earlier responses duplicated
the error on Win NT4 and 2000 (Rebol version not specified). Could it be a
bug in the freebie version?

Hi Sunanda,
I use REBOL/View/Pro on Win98 here and I see the problem with the grid
Cheers Phil

Hello,
As advised by some of you, I notified RT of the problem
through feedback. I let you know if there is any answer...
