qt 访问容器

#include <iostream>
#include <QString>
#include <QList>
#include <QListIterator>

int main(int argc, char *argv[]) {
    QList<QString> list;
    list << "One" << "Two" << "Three";

    foreach(QString s, list) {
        std::cout << s.toStdString() << std::endl;
    }

    QListIterator<QString> iter(list);
    while (iter.hasNext()) {
        std::cout << iter.next().toStdString() << std::endl;
    }

    QList<QString>::Iterator stlIter; // QList<QString>::iterator stlIter; // Ok
    for (stlIter = list.begin(); stlIter != list.end(); ++stlIter) {
        std::cout << stlIter->toStdString() << std::endl;
    }

    return ;
}
