TCollection.Move not implemented?

[AlexTP]

I can't see TCollection.Move() in fpc 3.0.2, so i must do workaround to change item index: Items[nFrom].Index:= nTo.
Pls publish Move() method.
It exists in TList.

Which Tlist? Classes? FGL? Generics.collections?

[AlexTP]

Classes.TList has Move method.

Which Tlist? Classes? FGL? Generics.collections?

I was also confused, then I saw the subject name :-)
"TCollection.Move not implemented?"

[AlexTP]

Yes, pls implement Move() in TCollection.

What is the problem in calling Collection.Item[ i].Index := new_index? Delphi's TCollection doesn't have it either.

[Mike.Cornflake]

I see, TCollectionItem.SetIndex call's FPList move().

The only problem I can see is that this is a un-intuitive.  The other lists in the unit have a Move(), so I understand Alextp's issue finding this solution.

I'd recommend slipping this request onto FPC Mantis, preferably with a patch.  The code for Move() should be simply, just set the index.
