有些时候我们在使用Delphi7的Listview过程中总是要改一些默认的设置，现在把它们集中起来汇总如下。
MultiSelect := True; 使Listview可以同时选择多行
GridLines := True; 使Listview显示格线
ViewStyle := vsReport; 显示数据项的详细列表
HideSelection := True; 使listview失去焦点时,选中行不高亮
//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.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;
这个功能存在一个问题：数字排序会按字符类似排，例如：1,10,102,3,34,356......感兴趣的读者可以加以完善
