写了个软件安装管理器，根据列表文件list.ini文件里的内容自动创建复选框，软件数量不固定，预设的swin太大滚动条下面会空很多，swin太小会放不下，代码如下：

_SUB MainWindow,W300H360,软件列表选择,,%windir%\system32\shell32.dll#316,15,,-top -disminb
    SWIN SWIN1:Page11:-SWINMAIN,L10T33W273H240,,0x140
    ENVI @SWINMAIN:SWIN1.ID=?&Swin1_Wid   //画框ID
    ENVI @SWINMAIN.ID=?&SWINMAIN_Wid    //与Page11窗口ID相同%&Page1_WID%
    LABE TitleLabel,L10T10W200H20,请选择要安装的软件：
    ITEM OKButton,L120T280W60H30,安装,CALL OnOK
_END

_SUB Page11,W600H240,,,,:0xFFFFFF

    READ list.ini,*,&&AllContent

            }

    LOOP #%&Index% <= %TotalCount%,

        CALC &Index=%&Index% + 1

CALL @MainWindow

代码运行后，swin不能实现滚动效果，参考官方实例搞不定，求教，谢谢
