[Laszlo-dev] how to get the extent of multiline text?

[Linsong]

Hi,All
   Now I encouter a problem, I need to get the extent of a multiline 
text component, like the following graph:

---------------------
|This is a multiline|
|text component of  |
|laszlo <=          |
|--------------------

   I want to get the width of the last line, in this case, it is the 
line with words "laszlo".I have read the documents of laszlo, but I find 
nothing about that. Does anybody have solution?
   Any comments will be welcomed !
   Thanks!
