[Qt-interest] Help getting out of Gridlayout Hell

Scott,

But let's say it is not a vertical group box but one with several
strips.  In other words:

label    combobox    label    combobox
label    combobox    label    combobox
label    combobox    label    combobox

I want the above layout in two different groupboxes such that the labels
and comboboxes are aligned.  The labels, however, are not all the same
size.

This seems like a reasonable thing to want to do and does not seem to
violate GUI norms.

...Jake
