Slice Qstring from right hand side

Question

I have a qstring of directory structure and need to take the second last element after "/" into a new qstring

"C:/Users/emb/Documents/AutoConnectTest/02/Job_0"

How to save 02 into a new QString

Answer 1

You can use QString split function.

Splits the string into substrings wherever sep occurs, and returns the list of those strings.

this code split all section by "/" and merge two second from last.

QString string = "C:/Users/emb/Documents/AutoConnectTest/02/Job_0"; 
QStringList lst = string.split('/');
qDebug() << lst[lst.count()-2] + "/" + lst[lst.count()-1];

Output:

"02/Job_0"
