Get the first child of the parent, then look for
siblings until you get to the last, spoiled
child. That's the old that breaks the bank when
it comes to college expenses. :-(

sib = event.id
child = event.id
WHILE sib NE 0 DO BEGIN
sib = Widget_Info(child, /SIBLING)
IF sib NE 0 THEN child = sib
ENDWHILE
lastsib = child

Cheers,

David
