Text cast members at the top of the screen representing the alphabet. User clicks on a letter. A field cast member on the screen then jumps to the first line whose first character matches the letter they've clicked on. I tried a repeat loop that went thru the entire field cast member, but it takes forever and the end result is that it doesn't scroll to the line I need. How does one find the first line in a field that matches the letter the user has clicked on?
the following handler works for #text and #field members:
on mScrollTo theText, targetMember
if targetMember.text.line[1] starts theText then
targetMember.scrollTop = 0
else
pos = offset(RETURN&theText, targetMember.text)
if pos then targetMember.scrollTop = (targetMember.charPosToLoc(pos)).locV
end if
end
mScrollTo "g", member("textORfield") should then scroll to the first line beginning with "g", if any.
and:
mScrollTo "gu", member("textORfield") should then scroll to the first line beginning with "gu", if any.
and: you can 'reset' it to the first line with:
mScrollTo "", member("textORfield")
