How to remove empty folders?

[merry]

Hi all

Working on Qt4.2 on my mac intel machine.

void MainWindow::ClearDir(QString dirRoot) 
{
      ClearAll(dirRoot);
      QDir d(dirRoot);
      d.cdUp();
      d.rmdir(dirRoot);
}
 
/*Function for erasing Folder*/
 
void MainWindow:: ClearAll(QString dirViewPath)
 {     
      QDir dirPath(dirViewPath); 
      QList<QFileInfo> infLst = dirPath.entryInfoList(QDir::AllEntries |     QDir::NoDotAndDotDot);
 
		foreach(QFileInfo finfo, infLst )
			{
				if(finfo.isDir() )
				{
					  ClearAll(finfo.absoluteFilePath());
					  dirPath.rmdir(finfo.absoluteFilePath());
				}
				else 
				{ //file
					  QString fileName = dirViewPath + "/" + finfo.fileName(); 
					  dirPath.remove(finfo.absoluteFilePath());
				} 
		}
}

void MainWindow::ClearDir(QString dirRoot) 
{
      ClearAll(dirRoot);
      QDir d(dirRoot);
      d.cdUp();
      d.rmdir(dirRoot);
}
 
/*Function for erasing Folder*/
 
void MainWindow:: ClearAll(QString dirViewPath)
 {     
      QDir dirPath(dirViewPath); 
      QList<QFileInfo> infLst = dirPath.entryInfoList(QDir::AllEntries |     QDir::NoDotAndDotDot);
		
		foreach(QFileInfo finfo, infLst )
			{
				if(finfo.isDir() )
				{
					  ClearAll(finfo.absoluteFilePath());
					  dirPath.rmdir(finfo.absoluteFilePath());
				}
				else 
				{ //file
					  QString fileName = dirViewPath + "/" + finfo.fileName(); 
					  dirPath.remove(finfo.absoluteFilePath());
				} 
		}
}

To copy to clipboard, switch view to plain text mode 

Using this code, I try to remove the existing dir selected using QFileDialog, I will be able to remove all the files but empty folders are left.
