QTableWidget's. setText() does not set any text to cells

[britsfp]

Hello,
I use QTableWidgetItem to insert some text to cells in a table but all that happens is that it crashes with a segmentation error. Code below:

QTableWidgetItem *item = new QTableWidgetItem;
item = ui->tablewidget->item(2, 2);
item->setText("danny");

so when the last line executes it crashes with a segmentation fault that takes me to some at header file ?.

any ideas?

regards

You are not setting the item in the cell first. item is null.

The fastest solution is to replace your 3 lines with:

auto model = ui->tablewidget->model();
model->setData(model->index(2,2),QStringLiteral("danny"));

Try,

QTableWidgetItem *item = new QTableWidgetItem;
item->setText("danny");
ui->tablewidget->setItem(2, 2, item);
