diplaying address enteries in qnetworkinterface

[rabeeah]

hi there,

i want to dipslay these ip addresses ,the braodcast and netmask on the screen.....i used the following to obatin the info
but i cant seem to get it on the screen

QList<QNetworkAddressEntry> entries;
entries = inter->addressEntries();

can smbdy plz tel me how to.....
i mean what command to use in a for loop?
thank u

Use qDebug for CLI and QListWidget for GUI.

yup ..i was trying to use Qlist widget...here is what i was trying to do...bt it gives an error : invalid use of operator "="


item->addItem( QString("Address entries:") );
for (int i = 0; i < entries.size(); ++i)
{
str = entries.at(i).broadcast(); // Show the IP address
item->addItem(str);
}
cn u plz guide me wat to do now?

item->addItem( QString("Address entries:") );
for (int i = 0; i < entries.size(); ++i)
{
str = entries.at(i).broadcast(); // Show the IP address
item->addItem(str);
}

sorry m probably nt following u on ths list problem...

in the code above.. str is of type Qstring and item of QListWidget... and the last statement add item allows only a string or a QListWidgetItem

now if i continue to use the above program, it gives me the following error

error: no match for 'operator=' in 'str = entries.QList<T>::at [with T = QNetworkAddressEntry](i)'

& if i use a QListWidgetItem for the str statement , it says the following..

error: cannot convert 'const QNetworkAddressEntry' to 'QListWidgetItem*' in assignment

m still nt clear wat to do....

ok i tried the qDebug command....the address entries are being shown as a console output now...
i used the following commands:
for (int i = 0; i < listInterNames.size(); ++i)
{
qDebug()<< listInterNames.at(i).addressEntries().at(i).ip()<<endl;
qDebug()<< listInterNames.at(i).addressEntries().at(i).broadcast()<<endl;

qDebug()<< listInterNames.at(i).addressEntries().at(i).netmask()<<endl;

}

this gives the following output,..(the ip, broadcast, netmask for one interface only...i.e...the loop executes once and then gives an error)
QHostAddress( "192.168.11.195" )

QHostAddress( "192.168.11.255" )

QHostAddress( "255.255.252.0" )

ASSERT failure in QList<T>::at: "index out of range", file ..\..\..\NokiaQtSDK\Simulator\Qt\mingw\include/QtCore/qlist.h, line 455

can u plz point out the mistake in this , v'd b highly grateful.

You have to use nested loop to print addressEntries list. I wonder how you produced listInterNames.

[rabeeah]

rite....thanks.....

the listinternames is workin fine with one loop....this is how i used it..

inter=new QNetworkInterface();
QList<QNetworkInterface> listInterNames;
QString str;


listInterNames = inter->allInterfaces();
listIpAddrs = inter->allAddresses();

// the names
item->addItem( QString("Interface names:") );
for (int i = 0; i < listInterNames.size(); ++i)
{
str = listInterNames.at(i).humanReadableName();
item->addItem(str);

}

[rabeeah]

well...i tried using nested loops for it......of what i understand, .the idea is to choose the ith interface from the listInterNames list and then use the j variable to print the broadcast, ip, & the netmask...
rite?.....

but i dn understand how do i do that....i mean ..how do i restructure "qDebug()<< listInterNames.at(i).addressEntries().at(i).ip()<<endl;" for two variables?

[divanov]

This is how one could do a nested loop

QList<QList> listOfLists;
for (int i = 0; i < listOfLists.size(); ++i) {
  QList<Item> list = listOfLists.at(i);
  for (int j = 0; j < list.size(); ++j) {
    Item item = list.at(j);
  }
}

dat workd!!....thanks a lot
