自绘ListBox的两种效果

　　本文利用Listbox自绘实现了两种特殊效果，其中第两种风格来自C Builder 研究 www.ccrun.com，老妖用BCB实现了，现在把它转换成Delphi代码。

演示图片：

unit DrawListItem;

interface

uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, StdCtrls, ImgList, jpeg, ExtCtrls;

TForm1 = class(TForm)

procedure lsbRightClick(Sender: TObject);
procedure FormShow(Sender: TObject);
procedure lsbLeftDrawItem(Control: TWinControl; Index: Integer;
Rect: TRect; State: TOwnerDrawState);
private

public
{ Public declarations }
end;

var
Form1: TForm1;
