help on QList<QTableWidgetItem*>

[roncriss]

how do iterate over QList retrieve the values then display them on a dialog for editing?
here is my function

void AddressBook::editItem()
{
 
   if( !tableWidget->currentItem())
    return;
   else
      QList<QTableWidgetItem*> selected = tableWidget->selectedItems();
      for (QList<QTableWidgetItem *>::iterator it=selected.begin();it!=selected.end();it++)
        {
           QString item[i] = (*it);
         }
 
      editDialog dlg;
           dlg.setId(item[0]);
           dlg.setname(item[1]);
           dlg.setemail(item[2]);
           dlg.setphone(item[3]);
           dlg.setgrossSalary(item[4]);
 
 
    if( dlg.exec() == QDialog::Accepted )
    {
        double HRA = dlg.grossSalary().toDouble() * 0.2;
        double transport = dlg.grossSalary().toDouble() * 0.1;
        double medical = 200.0;
 
           item[0] = dlg.id();
           item[1] = dlg.name();
           item[2] = dlg.email();
           item[3] = dlg.phone();
           item[4] = dlg.grossSalary();
 
           item[5] .setNum( item[4].toDouble() - HRA - transport - medical,'f',2 );   //netsalary
 
           item[6].setNum(item[5].toDouble() * 12,'f',4);
      ++row;
      for(int col = 0; col < 7 ; col++)
        {
 
        QTableWidgetItem *newItem = new QTableWidgetItem(tr("%1").arg(item[col]));
 
        newItem->setTextAlignment(Qt::AlignCenter);
 
        tableWidget->setItem(row, col, newItem);
        }
    }
 
}

void AddressBook::editItem()
{

   if( !tableWidget->currentItem())
    return;
   else

         }

      editDialog dlg;
           dlg.setId(item[0]);
           dlg.setname(item[1]);
           dlg.setemail(item[2]);
           dlg.setphone(item[3]);
           dlg.setgrossSalary(item[4]);


    if( dlg.exec() == QDialog::Accepted )
    {
        double HRA = dlg.grossSalary().toDouble() * 0.2;
        double transport = dlg.grossSalary().toDouble() * 0.1;
        double medical = 200.0;

           item[0] = dlg.id();

           item[4] = dlg.grossSalary();

           item[5] .setNum( item[4].toDouble() - HRA - transport - medical,'f',2 );   //netsalary

           item[6].setNum(item[5].toDouble() * 12,'f',4);
      ++row;
      for(int col = 0; col < 7 ; col++)
        {

        QTableWidgetItem *newItem = new QTableWidgetItem(tr("%1").arg(item[col]));

        newItem->setTextAlignment(Qt::AlignCenter);

        tableWidget->setItem(row, col, newItem);

did you include

#include <QList>

?

2 roncriss: This problem occur because you forgot about {} for else. Your code should be like that:

if( !tableWidget->currentItem())
    return;
else {
    QList<QTableWidgetItem*> selected = tableWidget->selectedItems();
 
    ....
}

if( !tableWidget->currentItem())
    return;
else {
    QList<QTableWidgetItem*> selected = tableWidget->selectedItems();

    ....
}
