Delphi中TListView控件使用

要点:

1.代码备注的超级详细，如下:

unit Unit1;
interface
uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls, ComCtrls;
type
  TForm1 = class(TForm)
    lv1: TListView;
    Button1: TButton;
    Button2: TButton;
    Button3: TButton;
    Button4: TButton;
    Button5: TButton;
    Button6: TButton;
    Button7: TButton;
    Button8: TButton;
    Button9: TButton;
    procedure Button1Click(Sender: TObject);
    procedure Button2Click(Sender: TObject);
    procedure Button3Click(Sender: TObject);
    procedure Button4Click(Sender: TObject);
    procedure Button5Click(Sender: TObject);
    procedure Button6Click(Sender: TObject);
    procedure Button7Click(Sender: TObject);
    procedure lv1CustomDrawItem(Sender: TCustomListView; Item: TListItem;
      State: TCustomDrawState; var DefaultDraw: Boolean);
    procedure lv1ColumnClick(Sender: TObject; Column: TListColumn);
    procedure FormCreate(Sender: TObject);
    procedure Button8Click(Sender: TObject);
    procedure Button9Click(Sender: TObject);
  private
  public
  procedure 分组(Sender: TObject);
  end;
var
  Form1: TForm1;
implementation
{$R *.dfm}
{风格}
procedure TForm1.Button1Click(Sender: TObject);
begin
  lv1.Clear; //清空
  lv1.Columns.Clear;
  //lv1.ViewStyle := lv1
{增加3项列表头}
  lv1.Columns.Add;
  lv1.Columns.Add;
  lv1.Columns.Add;
  lv1.Columns.Items[0].Caption:='时间';
  lv1.Columns.Items[1].Caption:='地点';
  lv1.Columns.Items[2].Caption:='人物';
  lv1.Columns.Items[0].Width:=100;
  lv1.Columns.Items[1].Width:=100;
  lv1.Columns.Items[2].Width:=300;
{设置属性}
  lv1.ViewStyle:=vsreport; //报表模式
  lv1.GridLines:=true;     //表格线
  //lv1.RowSelect := True;  //选中一整行
end;

{}

{插入数据方法1}
procedure TForm1.Button2Click(Sender: TObject);
begin
  with lv1.items.add do
  begin
  caption:='2013';
  subitems.add('上海');
  subitems.add('田攀');
  end;
end;

{插入数据方法2}
procedure TForm1.Button3Click(Sender: TObject);
var
  Titem:Tlistitem;//存储临时记录.
begin
  Titem := lv1.Items.add;
  Titem.Caption := '201314';
  Titem.SubItems.Add('广州');
  Titem.SubItems.Add('God');
end;

{删除行}
procedure TForm1.Button4Click(Sender: TObject);
begin
  lv1.DeleteSelected; //删除选中行
  lv1.Items.Item[2].Delete;//删除某一行
  lv1.Items.Clear;//清除所有数据
end;

{按标题内容删除}
procedure TForm1.Button6Click(Sender: TObject);
var
  I: Integer;
begin
  for I := 0 to lv1.Items.Count - 1 do
  begin
    if lv1.Items[I].Caption = '田攀2013' then //如果标题为 '田攀2013'
    lv1.Items.Item[I].Delete();//删掉
  end;
end;
{选择某行}
procedure TForm1.Button7Click(Sender: TObject);
begin
  lv1.SetFocus;//获取焦点
  lv1.Items[lv1.Items.Count - 1].Selected := True;//选中
end;

procedure TForm1.Button8Click(Sender: TObject);
begin
   分组(Sender);
end;
