我正在制作一个小程序来帮助文件阅读。
我有一个for循环从命令行接收命令:
for (i = 1; argc > i; i++)
{
QString path = QDir::currentPath()+ "/" + QString(argv[i]);
QDir dir(path);
fileSearch(dir);
}
从那里我调用另一种方法,我查看每个文件/ foler并获取大小以及它是文件还是文件夹。
void fileSearch(QDir dir)
{
foreach(QFileInfo info, dir.entryInfoList(QDir::NoDotAndDotDot | QDir::Files | QDir::AllDirs ))
{
if (info.isFile())
{
qDebug() << info.path() << "is a file! its size is:" << info.size() << endl;
}
if (info.isDir())
{
qDebug() << info.path() << "is a directory! its size is:" << info.size() << endl;
fileSearch(info.filePath());
}
}
而不是读取整个路径,我希望它只读取相对路径。所以不要阅读:
home/john/desktop/project/currentproject/checkdirectory is a directory! its size is: 4096
home/john/desktop/project/currentproject/checkdirectory/test.txt is a file! its size is: 4
我想要阅读:
checkdirectory/ is a directory! its size is: 4096
checkdirectory/test.txt is a file! its size is: 4
答案 0 :(得分:5)
QString QDir::relativeFilePath(const QString & fileName);
应该返回相对文件路径。
