2、OnDragOver事件：

?

1 2 3 4 5

procedure TForm1.ListView1DragOver(Sender, Source: TObject; X, Y: Integer; State: TDragState; var Accept: Boolean); begin 　　Accept := True; end;

3、OnDragDrop事件：

?

1 2 3 4 5 6 7 8 9 10 11 12 13

procedure TForm1.ListView1DragDrop(Sender, Source: TObject; X, Y: Integer); var   aItem, bItem: TListItem; begin   if (Source is TListView) then   begin     bItem := (Source as TListView).Selected;     aItem := (Source as TListView).Items.Insert((Source as TListView).Items.IndexOf((Source as TListView).GetItemAt(X, Y)));     aItem.Assign(bItem);     (Source as TListView).Selected.Delete;     aItem.Selected := True;   end; end;
