Hello everyone,
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
The rawKeyUp message should do what you want. I've used it before to
do what you are describing. Something like this:
on rawKeyUp pWhich
if pWhich is 65364 then # down arrow
put the hilitedLine of field "list1" into currentLine
if currentLine < the number of lines in fld "list1" then
add 1 to currentLine
set the hilitedLines of field "list1" to currentLine
end if
put the selectedText of fld "list1" into fld "showSelection"
else if pWhich is 65362 then # up arrow
put the hilitedLine of field "list1" into currentLine
if currentLine > 1 then
subtract 1 from currentLine
set the hilitedLines of field "list1" to currentLine
end if
put the selectedText of fld "list1" into fld "showSelection"
else
pass rawKeyup
end if
end rawKeyUp
