[Interest] When is QDir::Drives useful?

[Scott Aron Bloom]

AHHH... sorry...

In that case.. I believe you are correct...

int main( int argc, char ** argv )
{
    QDir root = QDir::root();
    QStringList drives = root.entryList( QDir::Drives );

    foreach( const QString & drive, drives )
    {
        qDebug() << drive;
    }
}


Returns nothing at all.. Infact, I don’t see the QDir::Drives used in the qfsfilesystem _win.cpp code at all...

It may have been created before the QDir::drives() existed...

"" is equivalent to ".", meaning the current directory.

(Note: this isn't a question about how to get a list of drives.  The
QDir::drives() function does that.  This is just a question about the intention of the QDir::Drives filter enum.)
