ListItem.Caption:='第一列内容'; ListItem.SubItems.Add('第二列内容'); end; →清空ListView1:ListView1.Items.Clear; →得到当前被选中行的行的行号以及删除当前行:For i:=0 to ListView1.Items.Count-1 Do If ListView1.Items[i].Selected then //i=ListView1.Selected.index begin ListView1.Items.Delete(i); //删除当前选中行 end;当然,ListView有OnSelectItem事件,可以判断选择了哪行,用个全局变量把它赋值出来。 →读某行某列的操作:Edit1.Text := listview1.Items[i].Caption; //读第i行第1列Edit2.Text := listview1.Items[i].SubItems.strings[0]; //读第i行第2列Edit3.Text := listview1.Items[i].SubItems.strings[1]; //读第i行第3列以次类推,可以用循环读出整列。 →将焦点上移一行:For i:=0 to ListView1.Items.Count-1 Do If (ListView1.Items[i].Selected) and (i>0) then begin ListView1.SetFocus; ListView1.Items.Item[i-1].Selected := True; end;不过在Delphi6中,ListView多了一个ItemIndex属性,所以只要ListView1.SetFocus;ListView1.ItemIndex:=3;就能设定焦点了。 Delphi的listview能实现交替颜色么?procedure TForm1.ListView1CustomDrawItem( Sender: TCustomListView; Item: TListItem; State: TCustomDrawState; var DefaultDraw: Boolean);var i: integer;begin i:= (Sender as TListView).Items.IndexOf(Item); if odd(i) then sender.Canvas.Brush.Color:= $02E0F0D7 else sender.Canvas.Brush.Color:= $02F0EED7;
