Qthread Problem

Hello friends,
I have created my custom thread class called SnifferThread. What i am doing in this thead is sniffing IP packets and whenever a packet is sniffed i am emitting a signal called gotPacket.

Code:

---

void mycustomthread::run()
{
                 while(!stopped)
                 {
                          // i here call the function used to grab packets
                          function_for_grabbingpackets()
                 }
                 stopped = false;
}
 
//function called from mainwindow when the stop button is clicked
void mycustomthread::stop()
{
    stopped = true;
    qDebug()<<"The thread has stopped running";
}
void function_for_grabbingpackets()
{
               //logic for grabbing packets
              // when a packet is arrived emit gotPacket()
}

---

my problem is that i want to insert a new row to my custom QTableWidget class whenever gotPacket() signal is emmited.
i know that i have to connect them in my main windows thread using signals and slots which i am doing like given below

connect(mycustomthread, SIGNAL(gotPacket()), mycustomQItemWidget, slot(addNewRow()))

in the add new row i am adding a new row like this
void mycustomQItemWidget::addNewRow()
{
int count = rowCount();
insertRow(count);
}

now what i wnt is that i want to pass the captured packet to my customtable so that i can fill the columns of my newly inserted row with the information i have got.
Please help me for how to achieve this. should i use signal and slots with parameters if yes how??
