cursor position before decimal or after
Posted: Sun Mar 01, 2015 12:29 am
Hi Guys,
I've been using this code below to enter in numeric values with a decimal. This seems to work fine, however, when there are 2 decimals in the field I want to continue to allow the entry of these valid characters if the cursor is before the decimal place with two digits. I therefore need to change this line of code "if length (item 2 of me) = 2 then exit keyDown" to detect the cursor position, and pass KeyDown if the number being keyed in is before the decimal with two digits. Can someone help me with the relevant code. I thought I could get cursor/caret position and then compare it with where the decimal, pass keydown if its before else exit keydown, but cant fund the commands i need in the dictionary.
Thanks
Jalz

Code: Select all
on keydown tKey
if tKey is in "-1234567890." then
if "." is in me then
if tKey is "." then
answer "You cannot have more than 1 decimal in this field"
exit keyDown
else
set the itemDelimiter to "."
if length (item 2 of me) = 2 then exit keyDown
pass keyDown
end if
end if
pass keyDown
end if
end keydown
Thanks
