I've got a scrolling group (named "OverlayAndImageGroup ") that is
composed of an image of a map, and numerous text fields and other
smaller groups. I have been trying to add the capability to use the
mouse's scrolling wheel to scroll the group "OverlayAndImageGroup" up
and down.
When I add to the group "OverlayAndImageGroup" the script
--below 3 handlers added 2007-12-18
on rawKeyDown theKeyNumber
--put theKeyNumber into msg
if theKeyNumber is 65308 then increaseScroll -- mouse wheel down
else if theKeyNumber is 65309 then decreaseScroll -- mouse wheel up
else pass rawKeyDown -- don't forget this!
end rawKeyDown
on decreaseScroll
set the vScroll of group "OverlayandImageGroup" to the vScroll of
group "OverlayandImageGroup" - 51
put the ScreenmouseLoc into thisLoc --below done to get calcLatLong
run to update latitude
set the ScreenmouseLoc to item 1 of thisLoc, item 2 of thisLoc + 1
end decreaseScroll
on increaseScroll
set the vScroll of group "OverlayandImageGroup" to the vScroll of
group "OverlayandImageGroup" + 51
put the ScreenmouseLoc into thisLoc--below done to get calcLatLong
run to update latitude
set the ScreenmouseLoc to item 1 of thisLoc, item 2 of thisLoc - 1
end increaseScroll
it works perfectly as long as I am in the "development" environment.
I also have built into this "Map" stack, the ability to measure
distances areas, etc., from a mouseDown handler in the "Map" stack
script, and to get latitude - longitude read outs from a mouseMove
handler in the "Map" stack's card level script. It, too works
perfectly as long as I am in the "development" environment (one has
to open a "Tools" palette to start measuring, a process that sets
globals that control the measuring processes).
BUT when I create a standalone (for both Mac and Windows), neither
the mouse scrolling wheel works to scroll the group
"OverlayandImageGroup" up or down, nor does the ability to measure
distances, areas, etc. work. The mouseMove does, however, continue
to feed into my lat-longitude script and give me lat & long.
Has anyone else run into this kind of a problem?
One can download the offending rev stack (18.2 MB unzipped, 6.5 MB
zipped) from the url
http://ddm.geo.umass.edu/ddm-umass/ddm-umass-2008-01-17-rev.zip
if you want to get to SAs that do work, visit the web page
http://ddm.geo.umass.edu/ddm-umass/index.html
I'm using Intel Macs (a MacBookPro and desktop Pro) and OS 10.4 &
10.5 and both Rev 2.8.1 and 2.9.0-dp-3 Build 520 and all behavior is
the same on the platforms, and on the Windows SA's I've created.

Along the same lines, is there a rawKeyDown code for left-right
scrolling? I've used Sarah's KeyCoder.rev project (thanks, Sarah!)
with no joy as well as the code:
on rawKeyDown pKey
put pKey into msg
end rawKeyDown
in a v and h scrolling field and get no rawKeyCode when i try to
scroll left-right
appreciate help.
