Problem in displaying directories in Tree widget

[aurora]

I am using a tree widget to display a file structure, directories , sub directories and files......
But the sub directories are not displaying in proper hierarchy....
Plz tell me the mistake i did here.

The code i wrote is:

bool MainWindow::DisplayDirs(QDir dir)
{
    std::cout<<"THE DIR DISPLAYING IS:"<<dir.dirName().toStdString()<<endl;
   bool ok=dir.exists();
   if(ok)
   {
       QFileInfoList dirContents=dir.entryInfoList();
       foreach(QFileInfo entryInfo,dirContents)
       {
           QString entryPath= entryInfo.absoluteFilePath();
           if(entryInfo.isDir())
           {
               QDir subDir(entryPath);
               AddRoot(subDir);
           }
 
       }
       if(ok && !dir.exists(dir.absolutePath()))
           ok=false;
       return ok;
   }
   return ok;
 
 
}

bool MainWindow::DisplayDirs(QDir dir)
{
    std::cout<<"THE DIR DISPLAYING IS:"<<dir.dirName().toStdString()<<endl;
   bool ok=dir.exists();
   if(ok)
   {
       QFileInfoList dirContents=dir.entryInfoList();
       foreach(QFileInfo entryInfo,dirContents)
       {
           QString entryPath= entryInfo.absoluteFilePath();
           if(entryInfo.isDir())
           {
               QDir subDir(entryPath);
               AddRoot(subDir);
           }

       }
       if(ok && !dir.exists(dir.absolutePath()))
           ok=false;
       return ok;
   }
   return ok;


}

        {

            AddRoot(subDir);
 
        }
    }

            AddRoot(subDir);

        }
    }
