procedure TQtTreeWidget.DetachEvents;
begin

  QTreeWidget_hook_destroy(FCurrentItemChangedHook);
  QTreeWidget_hook_destroy(FItemDoubleClickedHook);
  QTreeWidget_hook_destroy(FItemClickedHook);
  QTreeWidget_hook_destroy(FItemActivatedHook);
  QTreeWidget_hook_destroy(FItemChangedHook);
  QTreeWidget_hook_destroy(FItemSelectionChangedHook);
  QTreeWidget_hook_destroy(FItemPressedHook);
  QTreeWidget_hook_destroy(FItemEnteredHook);

  inherited DetachEvents;
end;                    

if I comment code like this then we have no AV's

procedure TQtTreeWidget.DetachEvents;
begin
(*
  QTreeWidget_hook_destroy(FCurrentItemChangedHook);
  QTreeWidget_hook_destroy(FItemDoubleClickedHook);
  QTreeWidget_hook_destroy(FItemClickedHook);
  QTreeWidget_hook_destroy(FItemActivatedHook);
  QTreeWidget_hook_destroy(FItemChangedHook);
  QTreeWidget_hook_destroy(FItemSelectionChangedHook);
  QTreeWidget_hook_destroy(FItemPressedHook);
  QTreeWidget_hook_destroy(FItemEnteredHook);
*)
  inherited DetachEvents;
end;                    

Paul , did U test your code under linux or just under Windows ?
I've test this under FC4 and FC7 and got same result.
