Editing a QTableWidgetItem and memory leaks

[AndresBarbaRoja]

Good day,
I'm trying to edit some QTableWidgetItem values and currently this is what I'm doing

QTableWidgetItem *temp = new QTableWidgetItem("String 1");
 QTableWidgetItem *power = new QTableWidgetItem("String 2");
 QTableWidgetItem *dutyCycle = new QTableWidgetItem("String 3");
 QString mnemo = "String";
 
 for(int i=0;i<29;i++)
 {
     QTableWidgetItem * head = ui->tLines_tableWidget->verticalHeaderItem(i);
     if (head->text()==mnemo)
     {
         ui->tLines_tableWidget->setItem(i,0,temp);
         ui->tLines_tableWidget->setItem(i,2,dutyCycle);
         ui->tLines_tableWidget->setItem(i,3,power);
         break;
     }
 }

QTableWidgetItem *temp = new QTableWidgetItem("String 1");
 QTableWidgetItem *power = new QTableWidgetItem("String 2");
 QTableWidgetItem *dutyCycle = new QTableWidgetItem("String 3");
 QString mnemo = "String";

 for(int i=0;i<29;i++)
 {
     QTableWidgetItem * head = ui->tLines_tableWidget->verticalHeaderItem(i);
     if (head->text()==mnemo)
     {
         ui->tLines_tableWidget->setItem(i,0,temp);
         ui->tLines_tableWidget->setItem(i,2,dutyCycle);
         ui->tLines_tableWidget->setItem(i,3,power);
         break;
     }
 }

To copy to clipboard, switch view to plain text mode 

My question is, what happens with the item that i'm replacing? I create the new items with "new" but i never delete them, so do i have a memory leak here?
If i'm losing memory here, how coud i avoid that?

Thanks in advance,
A.G.

Note that "The table takes ownership of the item." This means that the table is responsible for deleting the item at the appropriate time.

If, for some reason, you want to get the old item back and manage it yourself use "takeItem".
