Selection subsets

Can a selection set include another selection set? I want to handle
multiple groups of text items.

In short... No.

Long winded... I selection may contain all of the member of another
selection, but not a the actual selection set name.

Shoot. Then maybe I have to make a bunch of ssets and step through one
at a time.

Here's a non destructive selection set merge:

(defun mergess (ss_list / e tmp)
(setq tmp (ssadd))
(foreach s ss_list
(setq s (eval s)
i (sslength s))
(while (not (minusp (setq i (1- i))))
(setq e (ssname s i))
(if (not (ssmemb e tmp))
(ssadd e tmp))))
tmp)


(setq ss5 (mergess '(ss1 ss2 ss3 ss4)))

There are probably a lot of derivatives around for that 1. -David

 

David,

Not meaning to nit-pick but, ssadd doesn't add duplicate enames. So I guess the
ssmemb check isn't needed.

Good point, especially since (ssadd) is doing the
equivalent (ssmemb) check anyway, to determine if
the entity name already exists.

Thanks for the routine, David. In this case I actually don't want to
merge them, I want to deal separately with each sset. So the plan is to
stack the sset names in a list and peel them out one at a time. I'm
selecting items one at a time or in groups (especially text) to be
rotated in one command but around each set's default point. So each time
the user selects another set it keeps its identity. As to the rotation
point, I haven't decided, easy for single items and I suppose the insert
of the first item of a set. How to cope with overlapping selections?
Ignore 'em. Why is the user selecting the same item twice? Presumably
the double pick will rotate twice. Be fun to watch.
