It looks like currentRow() might return -1 sometimes
You are right, if nothing is selected, it returns -1...

Please correct me if I'm wrong (I'm just trying to understand QT).
I was a little vague in the above sentence on purpose, because when I
was experimenting with this code yesterday I noticed that even when
nothing is selected currentRow() returns 0 (or incidentally something
else > 0). That's why I added '&& formatLW->selectedItems().size() >
0' to the patch.
/*!
\fn void QListWidget::currentRowChanged(int currentRow)
This signal is emitted whenever the current item changes. The \a currentRow
is the row of the current item. If there is no current item, the \a
currentRow is -1.

I am not sure this is related, though, and I am not in the mood to
investigate ;-}
And of course, Vincent, you can always look at the Qt sources. I keep a
copy onhand for when I get real puzzled. There's a lot of code, but it's
reasonably well organized, once you get a sense for it. And of course,
grep is your friend.
