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!

代码文件:

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.

窗体文件:

  ClientWidth = 275
  Color = clBtnFace
  Font.Charset = DEFAULT_CHARSET
  Font.Color = clWindowText
  Font.Height = -11
  Font.Name = 'Tahoma'
  Font.Style = []
  OldCreateOrder = False
  PixelsPerInch = 96
  TextHeight = 13
  object ListView1: TListView
    Left = 8
    Top = 8
    Width = 250
    Height = 121
    Columns = <>
    TabOrder = 0
  end
  object Button1: TButton
    Left = 54
    Top = 141
    Width = 75
    Height = 25
    Caption = 'Button1'
    TabOrder = 1

  object Button2: TButton
    Left = 151
    Top = 141
    Width = 75
