The more elegant solution indeed!
Really displeased for not having thought of it ;-)
LOL

I have a list field, and as I use the Up and Down keys, I want to
display the contents of individual lines in another field. The
list field's handler below displays the lagged line and not the
one that was keyed to because the selected line doesn't change
until the pass arrowKey command is invoked and that has to happen
at the end for the line to change.
Not sure how to get what I want.
Gregory
on arrowKey theKey
if theKey is "Up" or theKey is "Down"
then
put the value of the selectedLine of the target into fld
"Display"
pass arrowKey
end if
end arrowKey
If you trap the selectionChanged message instead of arrowKey,
you'll not only get the message when you want it but also have an
update when the mouse is used to, from the same handler. You can
also get the value of the selected line by using the hilitedText
property:
on selectionChanged
put the hilitedText of the target into fld "Display"
end selectionChanged
Also, the "left" and "right" arrow keys have the same automatic
behavior as "up" and "down" respectively, so this selectionChanged
handler will handle those as well.
