It's not that easy. The dynamic linebreak makes the calculation of the
height rather difficult. At least if you are trying to break at word
boundaries. I tried it once and it was way to slow for >100 items. I'm
sure what I did wasn't the fastest solution, but the general problem
exists.
One idea I just had: QListViewItem can static line breaks. Don't
reimplement the painting but setup() and text() and insert the
linebreaks where needed.
