QMap历遍value

要遍历QMap的value，可以使用QMap的values()函数获取一个QList，然后使用foreach循环遍历该列表。以下是一个示例代码：

QMap<int, QString> map;
map.insert(1, "Apple");
map.insert(2, "Banana");
map.insert(3, "Cherry");
map.insert(4, "Grape");

foreach(QString value, map.values()) {
    qDebug() << value;
}

这段代码将输出QMap中所有的value值："Apple"、"Banana"、"Cherry"、"Grape"。\[2\]
