使用 TListView 控件(1)

第一次使用 ListView 是最近两三天的事: http://www.cnblogs.com/del/archive/2008/12/31/1365745.html

当时我就想: 一定要理顺它, 这是个常用且复杂的控件!

unit Unit1;



interface



uses

  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,

  Dialogs, StdCtrls, ComCtrls;



type

  TForm1 = class(TForm)

    ListView1: TListView;

    Button1: TButton;

    Button2: TButton;

    procedure Button1Click(Sender: TObject);

    procedure Button2Click(Sender: TObject);

  end;



var

  Form1: TForm1;



implementation



{$R *.dfm}



procedure TForm1.Button1Click(Sender: TObject);

begin

  ListView1.Items.Add.Caption := 'Item' + IntToStr(ListView1.Items.Count);

end;



procedure TForm1.Button2Click(Sender: TObject);

begin

  ListView1.Clear;

end;



end.
