QT得到本机IP时遇到了问题！！求助！！！

Question

QString Widget::getIP() //获取ip地址
{
QList list = QNetworkInterface::allAddresses();
foreach ( QHostAddress address, list)
{
if(address.protocol() == QAbstractSocket::IPv4Protocol)

   ui->textEdit->append(address.toString());
}
return 0;

}
这段代码编译后报错：D:\QT_Project\test_123\widget.cpp:26: error: 'address' was not declared in this scope
明明address明明声明了啊！

我用你代码测试了，代码没有问题。你再找找原因吧
