On reflection I would do as Patrick suggests - declare the structure as a
class
TNodeRecord = record ==> TNodeObject = class(TObject)
typ : TRecType; typ : TRecType;
... ...
my_pointer := new(TNo

I agree entirely Patrick, but when your existing application has screeds of
treeviews the objects are very convenient for a Q&D extension using the
existing node navigation.

I tried this, but had problems at the other end when I went to extract the items i.e.

I do this by creating the record structure with new first - eg
procedure add(strlst : TStringList; txt : string; [items for record] ...)
var
rec_ptr : ^TNodeRecord;
begin
new(rec_ptr);
rec_ptr^.ntype := typ;
rec_ptr^.level := level;
rec_ptr^.actionable := actionable;

Oh ok...will do thanks...

Change your record into a class derived from TObject.
The string list objects are designed to hold TObjects (which are pointers).
It looks like the complier can put a record with one integer field into the
space for a pointer which is why the first one worked.
