Scrolling field relative vScroll setting

I have a scrolling field that users type text into. Currently, if users input more text than can be seen in the size of the field they have to stop typing and manually move the thumbposition of the vScroll down to see what they are typing. I would like for the vScroll/thumbposition of the vScroll to reset itself automatically so that users do not have to manually move the thumb position to see what they are typing. I know this must be possible but I have not found the answer yet. ... using the line number strategy to reset the vScroll does not work because users' input is one continuous (wrapped) line of text. Any hints?

Hi cogpsych,
1. welcome to the forum!
2. I used something like this in the fields script in the past and looks like this still works:
Code: Select all
on keyup tk
## Instead of calculating the neccessary scroll from the fields content & its line height
## I set the scroll to some laughable number and LC does not complain :-D
set the scroll of me to 100000000
pass keyup
end keyup
Best
Klaus

The behavior described in the OP should be automatic. It has been on the platforms I've deployed to for many years.
cogpsych, what OS are you seeing this on, and in which version of LC?

Hi Richard,
The behavior described in the OP should be automatic.
it does, but not completely, see attached screenshot from LC 8.02 on OS X 10.11.6.

Bug. I'd report it so it can be fixed before 8.1 goes final.
