Delphi7中Listview的經常使用功效匯總。本站提示廣大學習愛好者：（Delphi7中Listview的經常使用功效匯總）文章只能為提供參考，不一定能成為您想要的結果。以下是Delphi7中Listview的經常使用功效匯總正文

有些時刻我們在應用Delphi7的Listview進程中老是要改一些默許的設置，如今把它們集中起來匯總以下。

MultiSelect := True;   使Listview可以同時選擇多行

GridLines := True;     使Listview顯示格線

ViewStyle := vsReport; 顯示數據項的具體列表

HideSelection := True;  使listview掉去核心時,選中行不高亮

//設置色彩
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; //選中行字體色彩
  Sender.Canvas.Brush.Color := clgray; //clGreen; 選中行高亮色彩
 end else begin
  Sender.Canvas.Font.Color := clNavy; //正常行字體色彩
  Sender.Canvas.Brush.Color := clWhite; //正常行高亮色彩
 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;

//排序功效
 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;

這個功效存在一個成績：數字排序會按字符相似排，例如：1,10,102,3,34,356......感興致的讀者可以加以完美
