justify text

[xbury.cs at clearstream.com]

Andrew,

I gave it a try to see...
First, if your line is wrapped (and assume we have 2 paragraphs wrapped 
over
5 lines), line 2 corresponds to paragraph 2. And wrapped line is not a 
line!

You can get the length of any part of the field (word, items) with some 
exceptions

put the  formattedwidth of word 3 of  fld 1

so you can recurse and find what you need. 
But after line 1... you have to fake the justification by breaking 
paragraph 1 into 
it's line components. Then adjust the formattedwidth of each line by 
inserting
spaces between the words (will look ugly!) so it matches the "effective 
formattedwidth" of the field. 

If you resize the field, it's all broken, start over...

It's easy with monospace fonts and a fixed width. 

But other factors such as the runrev definition of a word (which grabs any 
chars 
together regardless of punctuation, or grammar rules as a single word) 
will make
this a nightmare to parse! Option-space (non-breakable spaces or   in 
html)
will make it harder still...

Better of waiting until RunRev makes a better styled field with paragraph 
independent
styling and alignment...

cheers
Xavier
