1. List with Quick Find?

Hi all,
Some advise please!
How would one go about having a list of text (sortedList) and creating a 
control at the bottom where a user can enter text. As the user enters 
text the list would scroll to the nearest match.
 
soterdList
Enter character "T" into search text & scroll to 1st item with "T" in 
it.
Enter character "A" into text search & scroll to 1st item containing 
"TA".
Preferable not case sensitive.
 
Thanks
Tony Steward

The onChange event of the SearchText control is the place to put the hook.
Try this (untested):

procedure onChange_SearchText()

   integer index
   sequence text

   -- get the new text value
   text = getText( SearchText )

   -- search the SortedList
   index = 0
   for i = 1 to getCount( SortedList ) do
      if match( text, getItem( SortedList, i ) = 1 then
         -- found a match
         index = i
      elsif index then
         -- went too far
         exit
      end if
   end for

   -- set focus to last match
   setIndex( SortedList, index )

end procedure

I had written:

Ooops. This is *probably* better (but still untested):


procedure onChange_SearchText()
   sequence text

   -- get the new text value
   text = getText( SearchText )

   -- search the SortedList
   for i = 1 to getCount( SortedList ) do
      if match( text, getItem( SortedList, i ) = 1 then
         setIndex( SortedList, i )
         return
      end if
   end for

   -- no match
   setIndex( SortedList, 0 )

end procedure
