Qdir::filePath()函数文档不对

[{color:#007330}Q{color}| https://bugreports.qt.io/secure/qstring.html ]{color:#007330}String{color} QDir::filePath(const [{color:#007330}QString{color}| https://bugreports.qt.io/secure/qstring.html ] &fileName) const Returns the path name of a file in the directory. Does not check if the file actually exists in the directory; but see [{color:#007330}exists{color}| https://bugreports.qt.io/secure/qdir.html#exists-1 ](). If the [{color:#007330}QDir{color}| https://bugreports.qt.io/secure/qdir.html ] is relative the returned path name will also be relative. Redundant multiple separators or "." and ".." directories in fileName are not removed (see [{color:#007330}cleanPath{color}| https://bugreports.qt.io/secure/qdir.html#cleanPath ]()). Qdir::filePath()函数还具有将一个路径和一个文件名称合并的功能。如： QDir dst; QString s     dst=QDir({color:#008000}"f:/abf/1312"{color}); ,    s=dst.filePath({color:#008000}"e:/abc/file1.txt"{color}); s=dst.filePath({color:#008000}"e:/abc/file1.txt"{color}); 那么s={color:#008000}"e:/abc/file1.txt"{color} {color:#008000}而 {color}{color:#008000}s=dst.filePath("1.txt");{color} {color:#008000}s="f:/abf/1312/1.txt"{color} {color:#008000}完全不同的两种结果。而帮助文档上只给出了一种！！！！！！！{color}
