I’m a little confused by some references in the docs. Hopefully I can explain

Looking at TFPGList in fgl. The Sort method refers to a TCompareFunc (it does
not link to its definition). TFPGList says it’s methods are the same as
TFPSList or classes.TFPList. So looking in these two other classes their Sort
methods refer to TFPSListCompareFunc (in fgl) and TListSortCompare (in
classes), respectively.
type TListSortCompare = function(
Item1: Pointer;
Item2: Pointer
):Integer;
type TFPSListCompareFunc = function(
Key1: Pointer;
Key2: Pointer
):Integer of object;
Two questions.
1) Should TCompareFunc in TFPGList.Sort be one of the above types, or is there
another definition somewhere?
2) What is an “Integer of object” in TFPSListCompareFunc? (I expect it to be a
typo but then I’m fairly new to free pascal so I might have missed the memo.)
Thanks,
Pete

For question 1, I find the definition of TCompareFunc here
