Field Scroll Problem

I needed to enlarge a a Field and it’s Text in my stack. I used the Fields Basic Properties - Size & Position and Text Formatting - menu options to do so.
BUT now when I enter text from a script or open the stack the field scrolls to the top vs stay at the end of the entry.
Text entered from a script enters the last line of rge field correctly.
What am I missing?

That is the default for a text fld, to scroll to the top. If you need the fld to scroll to the bottom. You can change it by setting the vScoll of the fld.

I think what you'd be looking for would be more like this -

Scroll to the bottom of a field, accounting for size of font...
set the vscroll of fld "fData" to (the effective textheight of fld "fData") * (the number of lines in fld "fData")

Or you can set the scroll of the field to 10000000. That ought to be enough.

Googolplex, it is the only way to be sure
Just kidding, there are a lot of ways you can do it, or even fake it a bit.

As Craig said
set the vscroll of fld 1 to 100000000
put the vscroll of fld 1
Doesn't work ?
Which LC version do you use ?

Don't use smart quotes. Use ordinary quotes:
set the vscroll of fld "Play Result" to 100000000

set the vscroll of cd fld "Play Result" to 10000000
put the vscroll of cd fld "Play Result"
Works without an entry error BUT after data into the field, it still returns to the top line
vScroll = 0

Yes. I think that is what is expected.
What about this to display the end of text
Code: Select all
put myData into fld "Play Result"
set the vscroll of fld "Play Result" to 10000000
cd fld
I guess you're an hypercard baby (there is no cd fields in LC, only fields)

Just curious, did you try the script I posted above from the dictionary? Because that seems to be exactly what you are looking for as far as I can tell.
I made a test stack, 2 cards, a scrolling field named "Field" on the first, and a regular label on the second with the default name.
I put this code into the stack -
Code: Select all
on openCard
get the childControlNames of this card
if it is "Field" then
put "this new text is added by script" & cr after field "Field"
set the vscroll of field "Field" to (the effective textheight of field "Field") * (the number of lines in field "Field")
end if
end openCard
on mouseUp
go to the next card
end mouseUp
When I click on the card, it switched between the two cards, when it switched back to the scrolling field card, that field was always at the bottom regardless of whether text was added manually or by script to either the top or bottom of the field.
Unless I'm missing the point, isn't that what your trying to do?
