Delphi7, "Variable Required" error when accessing address of array element

Maybe try something like this

procedure TCRMEasyListview.getCheckedList(var ListToFill: TList);
var
  i: integer;
  ea: TEasyItem;
begin
    ListToFill.Clear;

    with Self.Items do begin
        for i:=0 to Count-1 do begin
            if Items[i].Checked then
             begin
             ea := Items[i];
                ListToFill.Add(ea);     //<-- "Variable Required" compiler error          
             end;
        end; // end of for loop
    end; // end of with declaration

end; // end of method

>>ListToFill.Add(@Items[i]);   // i think @ is the problem.Remove @ and try



procedure TCRMEasyListview.getCheckedList(var ListToFill: TList);
var i: integer;
begin
    ListToFill.Clear;

    with Self.Items do begin
        for i:=0 to Count-1 do begin
            if Items[i].Checked then
                //ListToFill.Add(@Items[i]);     //<-- "Variable Required" compiler error  
                ListToFill.Add(Items[i]);     //<--    
        end; // end of for loop
    end; // end of with declaration

end; // end of method

Thank you both for your answers

Giving directly the item gives error when trying to retrieve that.  You need to assign pointer to item and not item itself...

a) mokule:
Since I declare ea, I can assign it by "mylist.add(@ea)" and not ea directly for the reason I explained above.  But that gives me a question...

Doesn't declaration of ea give me memory leak?  When I declare ea and then assign as value the value held by the array item, I infact clone the array item to the ea variable.  That would give me memory leak.  If on the other hand I call "free" after i "add" my ea then the list will hold a nil.

So:

ea:=items[i];
mylist.add(ea); -> will compile but will give runtime error since ea is object and not pointer.
(This is similar approach to expert dinlud so, sorry it won't work)

------------------------

ea:=items[i];
mylist.add(@ea); -> correct but with memory leak

-------------

ea:=items[i];
mylist.add(@ea);
ea.free; --> Since mylist holds reference to ea object since I free it here, it wil have problem by the method that calls this code.

b) dinilud:

the "@" denotes "The address of".  Since I must add pointers to TList, I need it otherwise even though it compiles you get "Access Violation" runtime error.

Therefore its necessary to include either "@" or "Addr" to specify address of object referenced

Quite a wridle this question, ah? :)

Mokule is correct.  What you don't understand is that ea is also a pointer.  Delphi is just hiding that detail from you.  The actual object is a bunch of memory allocated on the heap.  You don't have to worry about using @ when storing objects in a TList, just dump them in there and use type casting to retrieve them.  I do it all the time.
