Data and ListView / ListItems / Listitem

Hey,

I dropped a custom object in the data pointer of the listitem.
Everything display well, but How do you acces the pointer or object?

listitem1:=listview1.Items.Add;
listitem1.Caption:=PKSRCDini1.pSRCDitem[int1arrayclassexist]].pname;
listitem1.Data:=PKSRCDini1.pSRCDitem[int1array[classexist]];

Thanks for your help

By typecasting the data pointer to your class!

var
  YourVar : TYourVar; // or your objecttype

begin
  if ListItem.data = nil then exit;
  YourVar := TYourVar(ListItem.data)
......
