I think there might be better approaches. :-)

You need to become intimate with XPAD, YPAD, and SPACE
keywords for WIDGET_BASE. :-)

If you are worrying about space issues, you must be programming
for Windows XP. It is the worst. I pretty much have resorted
to XPAD=0 and YPAD=0 as defaults. If I don't, there is no
room left for graphics. :-(

Cheers,

Hi,

the easiest trick is probably to write a (few) blank line before your group!

Thanks for the tip.

SPACE is useful.
YPAD helps a little but doesn't do quite what I was wanting. It puts
space both above and below the row. I was wanting space above row N,
or below row N-1 because there is a row N+1 where I don't want the
extra space... like a blank line between paragraphs in text.

I had also experimented a little with the ALIGN and BASE_ALIGN
keywords. But in my app they don't seem to have much affect at all.
