I never used the rowheight option myself, so I don't know for sure. I
figure that by default the rowheight is not set explicitely and thus the
widget will assign the required height for each row individually (for
example different sized icons might lead to different row heights);
probably when rowheight is explicitely given all rows will be the same
height, regardless of their contents (is this correct?).

Now, if you assume that in your case all rows have the same height,
I think using bbox(someitem)[3] should deliver the value you want (maybe
with one or two extra pixels added for borders). However if the heights of
the rows differ, this value might probably lead to rather disappointing
results :)

Best regards

Michael
