[Qt-interest] how to destroy a dir, no matter if any files in it or not.

[James Yan]

is any handy API do this?

OR why my function fail to do that :
//clear dir
void myClearDir(QString strDir)
{
	QDir dir(strDir);

	//clear the files
	QStringList fl = myListFiles(strDir,"*.*",true,false);
	for(int i=0;i<fl.size();i++)
	{
		dir.remove(fl.at(i));
	}

	//list dir and recall this func
	QStringList dl = myListDirs(strDir,true);
	for(int i=0;i<dl.size();i++)
	{
		myClearDir(dl.at(i));		
		dir.rmdir(dl.at(i));   // always return false, fail to delete the
empty dir? why?
	}	
}
