Selection Groups - Namrata - 04-19-2015
Hello,
I am developing a plugin which requires me to create 100 new vertex selection groups. Could someone please suggest How I can automatically generate these groups having the names like 'group_n' where n will be the group number going from 1-100.
Also, how exactly would I access the vertex number of the vertices added to a particular group?

It's late here, so if nobody else can help you I can try tomorrow or Monday.
But you can try find answers by looking in the code that manages it: https://github.com/dgud/wings/blob/master/src/wings_sel_cmd.erl

A rough sample of how to add ... (code below has not been compiled or determined to be syntactically correct.
Code:
SSELS = St0#st.ssels,
WeID = % YOU FIGURE IT OUT
MyAcc = fun(_Idx,Acc) ->
StrIdx = lists:flatten( io_lib:format("group_~p",[_Idx])),
SetVs =GetSet(_Idx, WeID), %% you must write this function
Key = {vertex,StrIdx},
Value = [{WeID, SetVs}]
gb_trees:enter((Key,Value,Acc),
end,
SSELS2 = lists:foldl(MyAcc, SSELS, lists:seq(1,100)),
St0#st{ssels=SSELS2}
