QString remove last characters

How to remove /Job from /home/admin/job0/Job

QString name = "/home/admin/job0/Job"

I want to remove last string after"/"

Solution

  • Find last slash with QString::lastIndexOf. After that get substring with QString::left till the position of the last slash occurrence

    QString name = "/home/admin/job0/Job";
int pos = name.lastIndexOf(QChar('/'));
qDebug() << name.left(pos);

    This will print: 

    "/home/admin/job0"

    You should check int pos for -1 to be sure the slash was found at all.

    To include last slash in output add +1 to the founded position

    qDebug() << name.left(pos+1);

    Will output:

    "/home/admin/job0/"
