Selection Sets

[Anonymous]

Hi.

I am a beginner at ObjectARX, so please bear with me if my question seems
dumb. When I select a bunch of objects, I get the ads_name back. Now then,
when converting this ads_name to resbuf, do I do that once, and then
traverse through the list of resbufs or do I do that for every ads_name (if
there are multiple), bumping the name pointer every time. I guess a shorter
way to ask this question is "does ads_name variable have a member field to
the effect of rbnext in resbuf, which would allow it to build a list of
ads_names?". So after I select multiple entities which case to I have
(below: A or B)?

note that -> in this case is used as a linked list pointer, not a subobject
data access.

A ads_name ->ads_name->ads_name->NULL and each ads_name converted
to its own resbuf list or

B ads_name standalone, where it's converted to multiple resbuf lists,
where the final node describing object 1 is linked to the header node
describing object 2 and so on?

C Something I haven't considered?

Thank you.

Alex/parahumaniod - How about posting under your real name?

An ads_name is not a resbuf. You would use the acedSSName()
function to get the ads_names of each entity in a selection
set. You could also use acdbGetObjectId() to get the object ids
of those ads_names.

ads_name pickset;
ads_name entity;
long sslen;

// Get the length of the selection set:

acedSSLength(pickset, &sslen);

// iterate over the entities in the selection
// set and process each.

for( long i = 0; i < sslen; i++)
if( acedSSName(pickset, i, entity) == RTNORM )
{
// here 'entity' is assigned to the
// ads_name of each entity in the selection set
// so do what you want with it.
}

Thanks for the advice.

Tony,

Very good point. There is little satisfaction in helping the anonymous
posters
with highly technical responses. Good on Alex for taking the hint.

Regards Gary.
