Hi all, some about lists and views

void MainWindow::FindLocalInterface()
{
 
 
    foreach( QNetworkInterface interface, QNetworkInterface::allInterfaces() ){
        foreach( QNetworkAddressEntry addressEntry, interface.addressEntries() ){
 
 
 
            ui->textEdit_2->append(( interface.humanReadableName()));
            ui->textEdit_2->append(( lookUpHost( QHostInfo::fromName( QHostAddress( addressEntry.ip() ).toString() ) ) ));
            ui->textEdit_2->append(( QHostAddress( addressEntry.ip() ).toString() ));
            ui->textEdit_2->append(( interface.hardwareAddress()));
            ui->textEdit_2->append(( QHostAddress( addressEntry.broadcast() ).toString()) );
            ui->textEdit_2->append(( QHostAddress( addressEntry.netmask() ).toString() ));
            ui->textEdit_2->append("\n\n\n");

Hi,

You can use a QComboBox.
Then use addItem() to add an entry to it.
Afterwards use currentIndex() and/or currentText() to get the item that is selected.

Best regards,
Marc

Thanks for reply Sorry for my bad english. I solved it, and here is my code..

void MainWindow::findLocal()
{
    model = new QStandardItemModel();
    model->setHorizontalHeaderLabels( QStringList() << "Connection Name" <<"Computer Name"
                                          <<"IP Address" <<"MAC Address" <<"BroadCast" <<"Netmask");
 
    ui->tableView->setModel(model);
 
    QList<QStandardItem *> itemList;
 
        // interfaces
        foreach( QNetworkInterface interface, QNetworkInterface::allInterfaces() ){
            foreach( QNetworkAddressEntry addressEntry, interface.addressEntries() ){
                itemList.clear();
                itemList << new QStandardItem( interface.humanReadableName());
                itemList << new QStandardItem( lookUpHost( QHostInfo::fromName( QHostAddress( addressEntry.ip() ).toString() ) ) );
                itemList << new QStandardItem( QHostAddress( addressEntry.ip() ).toString() );
                itemList << new QStandardItem( interface.hardwareAddress());
                itemList << new QStandardItem( QHostAddress( addressEntry.broadcast() ).toString() );
                itemList << new QStandardItem( QHostAddress( addressEntry.netmask() ).toString() );
                if (itemList.at(4)->text().isEmpty())
                    {
                        itemList.removeOne(itemList.at(itemList.count()));
                    }
                model->appendRow( itemList );
            }
        }
 
}
 
QString MainWindow::lookUpHost(const QHostInfo &host)
{
    if (host.error() != QHostInfo::NoError) {
        return "";
    }
 
    return host.hostName();
}

void MainWindow::findLocal()
{
    model = new QStandardItemModel();
    model->setHorizontalHeaderLabels( QStringList() << "Connection Name" <<"Computer Name"
                                          <<"IP Address" <<"MAC Address" <<"BroadCast" <<"Netmask");

    ui->tableView->setModel(model);

    QList<QStandardItem *> itemList;

        // interfaces
        foreach( QNetworkInterface interface, QNetworkInterface::allInterfaces() ){
            foreach( QNetworkAddressEntry addressEntry, interface.addressEntries() ){
                itemList.clear();
                itemList << new QStandardItem( interface.humanReadableName());
                itemList << new QStandardItem( lookUpHost( QHostInfo::fromName( QHostAddress( addressEntry.ip() ).toString() ) ) );
                itemList << new QStandardItem( QHostAddress( addressEntry.ip() ).toString() );
                itemList << new QStandardItem( interface.hardwareAddress());
                itemList << new QStandardItem( QHostAddress( addressEntry.broadcast() ).toString() );
                itemList << new QStandardItem( QHostAddress( addressEntry.netmask() ).toString() );
                if (itemList.at(4)->text().isEmpty())
                    {
                        itemList.removeOne(itemList.at(itemList.count()));
                    }
                model->appendRow( itemList );
            }
        }

}

QString MainWindow::lookUpHost(const QHostInfo &host)
{
    if (host.error() != QHostInfo::NoError) {
        return "";
    }

    return host.hostName();
}

Ok. i solved this too with delete some lines

Here is the code..

if (!itemList.at(4)->text().isEmpty())
                    model->appendRow( itemList );

if (!itemList.at(4)->text().isEmpty())
                    model->appendRow( itemList );

Yes 4 is the true coloumn... When i looked up my interfaces, there is more then 10 interface is showing. But just one has a broadcast number. I just want only show the live interface and i did it....

Thanks a lot

Edit:

Only connected interface's has a broadcast number... If you have more than 1 connection it will be listed..
