Question

void MainWindow::on_pushButton_clicked()
{
  Model *model = new Model;
  ui->tableView->setModel(model);
}

Where can I delete model object, please help.

Answer 1

You can just do

  Model *model = new Model(this);

This will set MainWindow as parent of the Model. MainWindow will delete the object when it gets destroyed itself.
