c++ - PushBack(push_back()) QStringList 的元素到 vector<string>

Question

如何访问 QStringList 的元素在vector<string>类型。 push_back不起作用。 insert ing 也需要另一个 vector仅输入。

#include <QtCore/QCoreApplication>
#include <QDebug>
#include <QStringList>
#include <vector>
#include <iostream>

using namespace std;

int main(int argc, char *argv[])
{
        QCoreApplication a(argc, argv);
        std::vector<string> vec;
        QString winter = "December, January, February";
        QString spring = "March, April, May";
        QString summer = "June, July, August";
        QString fall = "September, October, November";
        QStringList list;
        list << winter;
        list += spring;
        list.append(summer);
        list << fall;
        qDebug() << "The Spring months are: " << list[1] ;
        qDebug() << list.size();

        for(int i=0;i<list.size();i++)
        {
        //vec.push_back(list[i]);
        }
        exit(0);
        return a.exec();
}

我会这样做:

foreach( QString str, list) {
  vec.push_back(str.toStdString());
}
