stop ikeyvalue from managing value's memory

I have a idmaper:Ikeyvalue<Ptrint,Ttreenode> to store Ttreenodes that are already managed for their memory in a Ttreeview.
How can I stop Ikeyvalue from freeing the Ttreenode for this specific idmaper:Ikeyvalue<Ptrint,Ttreenode> instance
trying to change idmaper.Data.Values.Info.info after creating idmaper does not work. And there is no option loNoFinalize as with Ilists
Thank you in advance

Re: stop ikeyvalue from managing value's memory

Do not change idmaper.Data.Values.Info because it is the shared stateless RTTI info, global to the whole process!

You can set

idmaper.Data.Values.NoFinalize := true;

or use the newly introduced kvoNoFinalize option:

Really thank you a lot!!!

But Values is read property that can not be assigned

I was waiting for our guests arrival at our B&B.

We had to stay home and kill time.
