Help with QTableWidget!

[bottin]

Hi all,

I create a QTableWidget, with a determined number of rows and collumns, now i need initialize all values in 0, i can initialize this, but is so slowly. In this moment i use this method to make it.

size = rows = collumns

QTableWidgetItem *tableItem;
    tableItem = new QTableWidgetItem();
    tableItem->setText("0");
    for(int i=0; i < size; i++){
        for(int j=0; j < size; j++){
            ui->tableWidgetMatrix->setItem(i,j,tableItem);
        }
    }

QTableWidgetItem *tableItem;
    tableItem = new QTableWidgetItem();
    tableItem->setText("0");
    for(int i=0; i < size; i++){
        for(int j=0; j < size; j++){
            ui->tableWidgetMatrix->setItem(i,j,tableItem);
        }
    }

To copy to clipboard, switch view to plain text mode 

Is possible to make it diferent? Because i work with more than 500 rows and collumns!
Sorry my english, and thanks for helps!

Hi, instead of inserting new items for chance the value, use the already existing ones. Just change their values! -> QTableWidget::item().
And 500x500 changes need their time...

EDIT: also see QWidget::updatesEnabled().
