[Qt-interest] Help getting out of Gridlayout Hell

[Scott Aron Bloom]

So theproblem is not the margin of the label, but rather the location of
the combo boxes...

Unfortunately, I cant think of any easy way to have a layouts
"requirements" take into account another layout...

However, here is what you could do.. and it wouldn't be too difficult...

Since all six of your labels are "fixed" (not line edits) you could lay
the two grids out, then getting the minimum size hints for each label,
and setting the size to the maximum of the minimums..

It shouldn't be too hard, and is essentially what the layout system
does.
