Hello everyone.

Searching the Internet I found the following code and I decided to test, even though I did not see any relation.
And would you believe it, it worked !!!

Qt Code:

Switch view

int vnumRow=0;
 
    ui->GrdAdvogados->setRowCount(0);
    ui->GrdAdvogados->setSortingEnabled(false);  // I Added this code.
 
    ui->GrdAdvogados->insertRow(ui->GrdAdvogados->rowCount());
    vnumRow = (ui->GrdAdvogados->rowCount() - 1);
 
    ui->GrdAdvogados->setItem(vnumRow, 0, new QTableWidgetItem("Roberval da Costa"));
    ui->GrdAdvogados->setItem(vnumRow, 1, new QTableWidgetItem("777.555.222-88"));
    ui->GrdAdvogados->setItem(vnumRow, 2, new QTableWidgetItem("3.222.555"));
    ui->GrdAdvogados->setItem(vnumRow, 3, new QTableWidgetItem("SDS"));
    ui->GrdAdvogados->setItem(vnumRow, 4, new QTableWidgetItem("3.456-PE"));
    ui->GrdAdvogados->setItem(vnumRow, 5, new QTableWidgetItem("(81) 3421.3456"));
 
    ui->GrdAdvogados->item(vnumRow,1)->setTextAlignment(Qt::AlignCenter);
    ui->GrdAdvogados->item(vnumRow,2)->setTextAlignment(Qt::AlignCenter);
    ui->GrdAdvogados->item(vnumRow,3)->setTextAlignment(Qt::AlignCenter);
    ui->GrdAdvogados->item(vnumRow,5)->setTextAlignment(Qt::AlignCenter);
 
 
    ui->GrdAdvogados->insertRow(ui->GrdAdvogados->rowCount());
    vnumRow = (ui->GrdAdvogados->rowCount() - 1);
 
    ui->GrdAdvogados->setItem(vnumRow, 0, new QTableWidgetItem("Paulo Roberto Rego"));
    ui->GrdAdvogados->setItem(vnumRow, 1, new QTableWidgetItem("666.555.333-77"));
    ui->GrdAdvogados->setItem(vnumRow, 2, new QTableWidgetItem("4.111.444"));
    ui->GrdAdvogados->setItem(vnumRow, 3, new QTableWidgetItem("SDS"));
    ui->GrdAdvogados->setItem(vnumRow, 4, new QTableWidgetItem("1.999-PE"));
    ui->GrdAdvogados->setItem(vnumRow, 5, new QTableWidgetItem("(81) 3421.3333"));

    // ORDENAR GRID OCORRENCIAS PELA COLUNA PAGINAS (Qt::AscendingOrder)
    ui->GrdAdvogados->setSortingEnabled(true);
    ui->GrdAdvogados->sortByColumn(0,Qt::AscendingOrder);

int vnumRow=0;

    ui->GrdAdvogados->setRowCount(0);

    ui->GrdAdvogados->insertRow(ui->GrdAdvogados->rowCount());

Can anyone with more experience explain this?

Thanks in advance.
