Delphi 與 DirectX 之 DelphiX(7): 給 TDXImageList 加載圖片的最後方案

　本例效果圖:

　　代碼文件:

unit Unit1;
interface
uses
　Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
　Dialogs, DXDraws, StdCtrls;
type
　TForm1 = class(TForm)
　　DXDraw1: TDXDraw;
　　DXImageList1: TDXImageList;
　　Button1: TButton;
　　procedure FormCreate(Sender: TObject);
　　procedure Button1Click(Sender: TObject);
　end;
var
　Form1: TForm1;
implementation
{$R *.dfm}
procedure TForm1.FormCreate(Sender: TObject);
const
　ImgPath1 = 'C:TempDelphiX.bmp';
　ImgPath2 = 'C:TempDelphiX.jpg';
var
　PicItem: TPictureCollectionItem;
begin
　DXImageList1.DXDraw := DXDraw1;
　DXImageList1.Items.Add;
　PicItem := DXImageList1.Items[DXImageList1.Items.Count-1];
　PicItem.Picture.LoadFromFile(ImgPath1);
　DXImageList1.Items.Add;
　PicItem := DXImageList1.Items[DXImageList1.Items.Count-1];
　PicItem.Picture.LoadFromFile(ImgPath2);
end;
procedure TForm1.Button1Click(Sender: TObject);
begin
　with DXImageList1 do begin
　　Items[0].Draw(DXDraw.Surface, 0, 0, 0);
　　Items[1].Draw(DXDraw.Surface, 0, Items[0].Height, 0);
　　DXDraw.Flip;
　end;
end;
end.
