Qt中 对QList的排序

Qt中的qSort可以对Qlist 进行排序

1、 数组

QList list;

list <<12  <<13<<16<<10;

qSort(list.begin(), list.end());

//排序结果：[10，12，13，16]

2、多维的数组

头文件：

class PosSortResult

{

public:

    int agvpos;

    int posid;

}

 //多条任务 需要依次排序

    QList posSortBeforeList;

;

static bool subDevListSort(const PosSortResult* info1, const PosSortResult* info2);

    void devListSort(QList list);

.cpp文件

{

PosSortResult *possort = new PosSortResult();

    possort->agvpos = 1;

    possort->posid = 1;

    posSortBeforeList.append(possort);

    PosSortResult *possortt = new PosSortResult();

    possortt->agvpos = 9;

    possortt->posid = 3;

    posSortBeforeList.append(possortt);

    PosSortResult *possorttt = new PosSortResult();

    possorttt->agvpos = 7;

    possorttt->posid = 2;

    posSortBeforeList.append(possorttt);

    devListSort(posSortBeforeList);

}

void MainWindow::devListSort(QList list)

{

    qSort(list.begin(), list.end(), subDevListSort);

    for(int i = 0; i 

    {

        qDebug()<< i << list.at(i)->posid<< list.at(i)->agvpos;   

    }

}

bool MainWindow::subDevListSort(const PosSortResult *info1, const PosSortResult *info2)

{

    return info1->posid < info2->posid;  //升序排列   

 //return info1->posid < info2->posid;     //降序排列  

}
