ListCellRenderer - JLabel - String - n rows

ListCellRenderer - JLabel - String - n rows

So I have this situation:
I have a JList that displays a bunch of Strings.
However, these strings are really long and JList is really narrow. Meaning
the strings won't fit.
What I want to do is make each entry to have two rows, like this:
|Word word word |
|word word wor...|
It would do wordWrap for the first row, and then finish the secon't row by
cutting the rest of the string and appeinging the three dots to what is
left in a way maximum space is filled.
It doesn't really matter what I do, the important thing is that I have to
use FontMetrics to measure all this stuff so I can make it work. And
that's the catch.
Until whole getListCellRendererComponent(...) method is executed, the
component will not be painted, thus having no graphics, thus making any
font measurement impossible.
How do I get around it?
P.S. I need to use the JLabel for the visuals.
