QTDir why not display all the folder in the root "/" in MacOs?

Question

I'm starting to use QT, and trying QDir I copy the example in the references of QT the one which listing the content of a folder.

I'm trying to listing the content of the root path in a MacOS snow leopard, version of QT 5.1.1 But don't appear all of it :S

This is the code:

QFileInfoList list = QDir::root().entryInfoList();
for(int i=0; i<list.count(); i++){
    cout<< list[i].fileName().toStdString()<<endl;
}

But the output of this program is:

.
..
Applications
Developer
Library
opt
sockets.log
System
Users

When I think it should be: I know that ls -l don't show . and .. my worry is about the other folders, I put a line break separating the folders that appears in the output and ones who don't.

$ ls -l /

Anyone can tell me why the other folders not appear?

Thanks :)

Add filter to entryInfoList

On Unix entryInfoList() does not list hidden files. You have to "ask" for them. I think it will be similiar on Mac.

QFileInfoList list = QDir::root().entryInfoList(QDir::AllEntries | QDir::System | QDir::Hidden);
for(int i=0; i<list.count(); i++){
    cout<< list[i].fileName().toStdString()<<endl;
}
