Check how deep folder is compared to other folder

[Eligijus]

Hello,

Lets say I have base folder /test
I wonder if there is something standard in Qt that would let me know how deep I am from base folder.
I.e. My other folder is /test/sample/end and comparing to base folder it would return 2 then /test/sample would return 1 and /test would return 0.

Try:

int countDepth(QDir directory){
int result;
for(result=0;directory.cdUp();++result){}
return result;
}

@VRonin I have tried it and added check to see if folder includes base folder

QDir basePath("/home/something/test");
QDir t("/home/something/test/sample/end");
QDirIterator it(basePath, QDirIterator::Subdirectories);

bool isBase = false;

while (it.hasNext()) {
    if (it.next() == t.path()) {
        isBase = true;
        break;
    }
}

int i = 0;
if (isBase) {
    while (basePath.path() != t.path()) {
        t.cdUp();
        i++;
    }
} else {
    i = - 1;
}

qDebug() << i;

if t is not a subdirectory of basePath this is an infinite loop

@VRonin Huh? I'm checking with QDirIterator if t is a subdirectory of basePath and setting isBase then only if isBase is true i'm going into loop. I have tested and it's working as intended or am I missing something here?
