[Interest] Changing permissions in a dir

[Sensei]

Dear all,

I am trying to figure out how to change permissions "recursively" of 
every item in a directory.

I've tried the code below but I found that I have two problems.

First: the code won't work and stops after descending into the target 
directory... and I cannot figure out why!

Second: can I change permissions of a directory?

This is the code:


     QStack<QString> dirs;

     // fileName_: I need to change permissions in there
     dirs.push(QFileInfo(fileName_).absolutePath());

     while (!dirs.isEmpty())
     {
         // Get dir
         QDir d(dirs.pop());
         QFileInfoList list = d.entryInfoList(QDir::NoDotAndDotDot);

         // Set dir permissions of dir?
         qWarning("> into %d-%d %s", dirs.count(), list.count(), 
qPrintable(d.absolutePath()));

         for (int i = 0; i < list.count(); i++)
         {
             QFileInfo info = list[i];

             if (info.isFile())
             {
                 qWarning("set permission of file %s", 
qPrintable(info.absoluteFilePath()));
                 QFile f(info.absoluteFilePath());

                 bool b = f.setPermissions(f.permissions() | 
QFile::WriteUser);
                 if (!b) qWarning("ERR");
             }

             if (info.isDir())
             {
                 qWarning("PUSH %s", qPrintable(info.absolutePath()));
                 dirs.push(info.absolutePath());
             }
         }

     }



And this is the output, which is quite self-explanatory:

 > into 0-0 /Users/sensei/Desktop/mydir


The directory exists, and contains files and directories.

If you can lend a hand I'd be really happy!


Thanks & Cheers!
