Scott,
Hmmm. I thought I tried that but will try it again.
The comboboxes are all specified to be the same size. The labels are
all of varying sizes. You are suggesting that I get the max of minimum
size hint since that is the minimums size required to display the
longest label. I should set every label's minimum size (using
setMinimumSize() method) to the output of the size() method?
