I'm trying to display information as pseudo tables in text field
using MC2.3.1 on both Mac and Win.
I have created field with a set of tabStops and the horizontal and
vertical grid liens are displayed. The text in the field is in Arial
12pt, plain, say. What I'm trying to do is write a function that
will truncate a chunk of text such that it is guaranteed to fit
inside the available pixel width in any given column.
I need such a function as I want to be sure that any arbitrary text
placed in a colunm will not overflow and cause content in the columns
to the right to overflow.
The function I have developed so far is as follows:
function colTrimmed theText, theField, theCol
put the tabStops of field theField into theTabs
replace comma with tab in theTabs
set itemDelimiter to tab
put number of items in line 1 of field theField into maxCol
if theCol = maxCol then
put width of field theField - last item of theTabs into colWidthPixels
else
if theCol = 1 then
put item theCol of theTabs - 1 into colWidthPixels
else
put item theCol of theTabs - item (theCol-1) of theTabs into
colWidthPixels
end if
end if
put colWidthPixels div (the effective textSize of field theField)
into maxChar
return char 1 to maxChar of theText
end colTrimmed
However, it always seems to be too conservative! For example if the
column can accommodate 20 chars (all "0"), it will produce a maximum
width of 12 characters.
Any suggestions please?
Cheers
Peter
