Qt WiFi network scan - c++

Question

For some application I need to scan WiFi searching for available network (SSID). On Ubuntu 18.04 LTS I don't have any issue with the fallowing code. It return all available SSID as expected but when running on Raspbian stretch (Rasberry PI 3 b) the fallowing code is returning the interface wlan0 and eth0 and not the SSID. Does someone have any clue why? or can tell me what I miss? On the other hand, is it better not to use Qt network lib and use a QProcess and parse what sudo iwlist wlan0 scan is returning?
.cpp
void wificonfig::findavailableWifinetwork( void )
{
QNetworkConfigurationManager ncm;
netconflist = ncm.allConfigurations(QNetworkConfiguration::Discovered); //
int i =0;
awifilist.clear();
for(auto &x : netconflist){
if ((x.bearerType() == QNetworkConfiguration::BearerWLAN) ){
if(x.name() == "")
awifilist << "Unknown(Other Network)";
else{
ui->wificonnection_tw->setItem(i, 0, new QTableWidgetItem(x.name()));
i++;
}
//qDebug() << x.type();
}
}
ui->wificonnection_tw->setRowCount(i);
}
