Ha. I hope I didn't screw up this time.
#include <QCoreApplication>
#include <QDir>
#include <QDebug>
// returns true if 'a' is a subdirectory of 'b'
bool isSubdirectory(QDir a, QDir b)
{
while (!a.isRoot()) {
if (a.absolutePath() == b.absolutePath())
return true;
a.cdUp();
}
return false;
}
int main(int argc, char *argv[])
{
QCoreApplication app(argc, argv);
QDir a("/Users/olegyadrov/one/two/three");
QDir b("/Users/olegyadrov/one/two");
QDir c("/Users/olegyadrov/one/four");
qDebug() << isSubdirectory(a, b);
qDebug() << isSubdirectory(a, c);
return app.exec();
}

Except that this has a bug (which we had in Qt too): these two directories are
considered to be parent-child, when they're not
C:\One\TwoAndTwenty
C:\One\Two
And since we're talking about Windows, you also need to use case-insensitive
comparison.
