在QMap中嵌套QList

刚接触QT的QMap比较困惑，看这名字以为是二维数组

因为我把QList当作一维数组来用了，事实上也确实可以，但只当一维数组太浪费了。可参考别的资料

QMap<QString, QList<QString> > panelStatistics;    QList<QString> panelInfo;    panelInfo.push_back("0102");    panelInfo.push_back("1253");    panelInfo.push_back("1256");    panelStatistics.insert("面板1", panelInfo);    QMap<QString, QList<QString> >::iterator it;    for(it = panelStatistics.begin(); it != panelStatistics.end(); ++it)    {            QList<QString> tmp = it.value();            qDebug()<<it.key() <<" "<< tmp[0] <<" "<< tmp[1] <<" "<< tmp[2];    }

如果你和我一样，非得把QMap用成二维数组

那么你这可这样

//在初始化的时候这样QMap<int, QList<Qstring> > tableDate;QList<Qstring> tmp;for(int i = 0; i < 10; i ++){tmp.clear();tmp.push_back("monday in row"   + QString::number(i));tmp.push_back("tuesday in row"  + QString::number(i));tmp.push_back("wensday in row"  + QString::number(i));tmp.push_back("thursday in row" + QString::number(i));tmp.push_back("friday in row"   + QString::number(i));tmp.push_back("sateday in row"  + QString::number(i));tmp.push_back("sunday in row"   + QString::number(i));tableDate.insert(i, tmp);}//取值可以这样QList<Qstring> result;result = tableDate.value(3);for(int i = 0; i < reslut.length; i ++){qDebug() << result[i] + " ";}

你还可以这样，类似于数据库操作一样

QMapIterator<int, QList<QString> > iter(tableDate);QList<QString> whatDate;while(iter.hasNext()){iter.next();if(whatDate = iter.value()){qDebug() << whatDate[0];qDebug() << whatDate[1];qDebug() << whatDate[2];qDebug() << whatDate[3];}}
