QT中获取IP地址的问题！求助！

ckc陈

QString Widget::getIP()  //获取ip地址
{    QList<QHostAddress> list = QNetworkInterface::allAddresses();
    foreach ( QHostAddress address, list)  
  {       if(address.protocol() == QAbstractSocket::IPv4Protocol)
       ui->textEdit->append(address.toString());    }   
    return 0;
}
编译后报错D:\QT_Project\test_123\widget.cpp:26: error: 'address' was not declared in this scope
        if(address.protocol() == QAbstractSocket::IPv4Protocol)adress明明声明了啊 ，怎么回事呢？
           ^

确认一下你变量的作用域，不是说声明了就一定能被编译器识别
