将QFile储存在QHash中

#include <QHash>
#include <QString>
#include <QFile>
#include <QTextStream>
#include <QFile>
#include <QDebug>

int main(int argc, char *argv[])
{
QHash <qint32,QFile *> fileHandHash;
for(qint32 i=0; i<1000; i++){
qint32 id = i % 10;
qDebug() << i << "\t" << id;

if( ! fileHandHash.contains(id) ){
QString filename = id + ".out.txt";
QFile MYFILE(filename);
MYFILE.open(QIODevice::WriteOnly);
fileHandHash.insert(id,&MYFILE);
}

QTextStream OUT(fileHandHash[id]);
OUT << i << "\n";
}
return 1;
}

运行的时候出现下面的错误：

QObject::connect: No such signal QObject::aboutToClose() in ....includeQtCore5.3.2QtCore/private/../../../../../src/corelib/io/qtextstream_p.h:75
谢谢大家！
