Getting the directory from a path

fcarney

I have a path like this:

C:/ProgramData/XM Editor/RnD/data/2018-07-01/defaultprog 2018-07-01 14h 53m.csv

I only want this:

C:/ProgramData/XM Editor/RnD/data/2018-07-01

I can get the filename on its own, but I cannot find a simple way to get the directory name only. I don't want to use string processing that is not cross platform. So far I have looked at these objects:

QDir
QUrl
QFileInfo

I have tried numerous functions and they all return either just the filename or the entire path including the filename. There has to be a simple way to do this that I am overlooking.

Hi
What about
https://doc.qt.io/qt-5/qfileinfo.html#absolutePath
"Returns a file's path absolute path. This doesn't include the file name."

Well this is kinda hackish:

    QString csv_filename; // set somewhere else
    QString basename = QUrl(csv_filename).fileName();
    QString basepath = csv_filename.remove(basename);

This seems to work and I need both parts.

Hi

 QFileInfo fi("e:/folder name/file name with space.txt");
 qDebug() << fi.absolutePath() << " fn=" << fi.fileName();

gives
"E:/folder name" fn= "file name with space.txt"

Did i miss something ?

What happens if your basename occurs not only at the end but also somewhere in the middle?

/something/basename/somethingelse/basename

What is wrong with the QFileInfo methods @mrjj suggested which do just what you want? [He's just posted exactly what you need.]
