Delphi7中Listview的常用功能汇总

//设置颜色procedure TForm1.ListView1CustomDrawItem(Sender: TCustomListView; Item: TListItem; State: TCustomDrawState; var DefaultDraw: Boolean);var subRect, itemRect: TRect; i, SubItem: Integer;begin DefaultDraw := False; if Item.Selected then begin  Sender.Canvas.Font.Color := clRed; //选中行字体颜色  Sender.Canvas.Brush.Color := clgray; //clGreen; 选中行高亮颜色 end else begin  Sender.Canvas.Font.Color := clNavy; //正常行字体颜色  Sender.Canvas.Brush.Color := clWhite; //正常行高亮颜色 end; itemRect := Item.DisplayRect(drLabel); subRect := itemRect; for SubItem := 0 to (Sender as TListView).Columns.Count - 1 do begin  subRect.Left := itemRect.Left;  for i := 1 to SubItem do  begin   subRect.Left := subRect.Left + (Sender as TListView).Column[i - 1].Width;   subRect.Right := subRect.Right + SubRect.Left + (Sender as TListView).Column[i].Width;  end;  if SubItem = 0 then  begin   subRect.Right := subRect.Right + 2;   Sender.Canvas.TextRect(subRect, subRect.Left, subRect.Top, Item.Caption);  end else   Sender.Canvas.TextRect(subRect, subRect.Left, subRect.Top, Item.SubItems[SubItem - 1]); end;end;

//排序功能 private  { Private declarations }  SortCol: Integer;  SortWay: Integer; procedure TForm1.ListView1ColumnClick(Sender: TObject; Column: TListColumn);begin SortCol := Column.Index; if (SortWay = 1) then SortWay := -1 else SortWay := 1; (Sender as TCustomListView).AlphaSort;end;procedure TForm1.ListView1Compare(Sender: TObject; Item1, Item2: TListItem; Data: Integer; var Compare: Integer);var t: Integer;begin if (SortCol = 0) then begin  Compare := SortWay * CompareText(Item1.Caption, Item2.Caption); end else begin  t := SortCol - 1;  Compare := SortWay * CompareText(Item1.SubItems[t], Item2.SubItems[t]); end;end;
