Re: align field scrolls

2017-03-06 Thread Nicolas Cueto via use-livecode
Mike Bonner's solution -- using selectedLoc to set vScroll -- matches
exactly the scrolling effect I'm after.

Thank you, everyone. And, thank you Mike!

Re: align field scrolls

2017-03-06 Thread Mike Bonner via use-livecode
An alternate solution..
If you
put item 2 of the selectedloc of the first field - item 2 of the
selectedloc of the second field into tScroll

-- you can then
set the vscroll of field "your second field" to the vscroll of field "your
second field" - tScroll

Re: align field scrolls

2017-03-06 Thread Paul Dupuis via use-livecode
You need 3 controls: 2 fields with the vertical scrollbars turned off
and a vertical scroller


Set the min of the vertical scrollbar to 0 and the max to the "max(the
formattedHeight of field X,formattedHeight of field Y)

In the scrollbar, add the script:

on scrollbarDrag newPosition
  set the vScroll of field X to newPosition
  set the vScroll of field Y to newPosition
end scrollbarDrag

Re: align field scrolls

2017-03-06 Thread dunbarx via use-livecode
So if your two fields have different number of lines, you must scale the
"slave" field to the "master. You cannot just align their scroll values.

If the master has, say 100 lines, and the slave 75, you simply set the ratio
of the scroll of the master to its total line count to the ratio of the
slave's similar properties. You may need the "trunc" function to avoid
unnecessary pain and suffering.

Hi Nicolas,

Does the number of lines increase or decrease between executions?

Have you tried to add or subtract a constant to adjust for the difference?

​I should've added that the fields do not contain the same number of
lines.  They are identical, though, in size and text properties.

Re: align field scrolls

2017-03-05 Thread Paul Hibbert via use-livecode
I have a stack that does a similar thing, but with numbers and I just use the 
following script in the main field;

on scrollBarDrag pScroll
   set the vScroll of fld  “lineNumbers" to pScroll

end scrollBarDrag

Provided both fields have the same number of lines and the text properties are 
identical they should stay aligned correctly.

Or a simpler version would be;
set the vScroll of fld 2 to the vScroll of fld 1
