谁能解释清楚下面代码？

#include"apdefap.h"
voidOnClick(char*lpszPictureName,char*lpszObjectName,char*lpszPropeRTyName)
{
//wincc:TAGNAME_SECTioN_START
//syntax:#defineTagNameInActionDMTagName
//nextTagID:1
#defineApcTitleText"TitleText"
//WINCC:TAGNAME_SECTION_END

//WINCC:PICNAME_SECTION_START
//syntax:#definePicNameInActionPictureName
//nexTPicID:1
//WINCC:PICNAME_SECTION_END

SetPrOPChar("@Start.PDL","Hintergrund","PictureName","CASTING_PLATFORM1.PDL");
SetTagWord(ApcTitleText,3);
}

最佳答案

SetPropChar("@Start.PDL","Hintergrund","PictureName","CASTING_PLATFORM1.PDL");
@Start.PDL：画面名称
Hintergrund：窗口名称
PictureName：窗口属性——画面名称
CASTING_PLATFORM1.PDL：需要写入窗口的画面名称
该语句表示，将画面名称"CASTING_PLATFORM1.PDL写入一个存放在@Start.PDL画面中的窗口Hintergrund中。

#defineApcTitleText"TitleText"
变量预定义
SetTagWord(ApcTitleText,3);
将数值3写入变量TitleText中
