如何克隆图标

在Windows中，给定一个图标（ HICON ）的句柄，你如何克隆它？

例如

 HICON CloneIcon(HICON OriginalIcon) { ICON clone; //... return clone; }

使用Win32 API函数DuplicateIcon ：

 HICON CloneIcon(HICON OriginalIcon) { return DuplicateIcon(NULL, OriginalIcon); //first parameter is unused }

这里是克隆图标的Delphi代码。

 function CloneIcon(ico: HICON): HICON; var info: ICONINFO; bm: BITMAP; cx, cy: Integer; begin //Get the icon's info (eg its bitmap) GetIconInfo(ico, {var}info); //Get the bitmap info associated with the icon's color bitmap GetObject(info.hbmColor, sizeof(bm), @bm); //Copy the actual icon, now that we know its width and height Result := CopyImage(ico, IMAGE_ICON, bm.bmWidth, bm.bmHeight, 0); DeleteObject(info.hbmColor); DeleteObject(info.hbmMask); end;

在我脑海中转换成C / C＃风格的语言：

 HICON CloneIcon(HICON ico) { ICONINFO info; //Get the icon's info (eg its bitmap) GetIconInfo(ico, ref info); //Get the bitmap info associated with the icon's color bitmap BITMAP bm; GetObject(info.hbmColor, sizeof(bm), &bm)); //Copy the actual icon, now that we know its width and height HICON result = CopyImage(ico, IMAGE_ICON, bm.bmWidth, bm.bmHeight, 0); DeleteObject(info.hbmColor); DeleteObject(info.hbmMask); return result; }
