相关代码段如下：
void MainWin :: getHostInformation()
{
QString localHostName=QHostInfo :: localHostName();
LineEditLocalHostName->setText(localHostName);
QHostInfo hostInfo=QHostInfo :: fromName(localHostName);
QList<QHostAddress> listAddress=hostInfo.addresses();
if(!listAddress.isEmpty())
{
LineEditAddress->setText(listAddress.first().toString());
}
}
void MainWin :: slotDetail()
{
QString detail="";
QList<QNetworkInterface> list=QNetworkInterface :: allInterfaces();
for(int i=0; i<list.count(); i++)
{
QNetworkInterface interface=list.at(i);
detail=detail + tr("Device: ") + interface.name() + "\n";
QString hardwareAddress=interface.hardwareAddress();
detail=detail + tr("HardwareAddress: ") + interface.hardwareAddress() + "\n";
QList<QNetworkAddressEntry> entryList=interface.addressEntries();
for(int j=0; j<entryList.count(); j++)
{
QNetworkAddressEntry entry=entryList.at(j);

}
}
QMessageBox :: information(this, tr("Detail"), detail);
}
请哪位大侠指点，谢谢！！！
