Qt tablewidget Judge whether a row is selected and obtain the data of the selected row

Look directly at the code ：

1. Get all column data of the selected row

QList<QTableWidgetItem*> items = ui->tableWidget->selectedItems();
int count = items.count();
for(int i = 0; i < count; i++)
{
    
	int row = ui->tableWidget->row(items.at(i));
	QTableWidgetItem *item = items.at(i);
	QString text = item->text(); // Get content 
}

2. Get the first column data of the selected row and judge whether a row is selected

 QList<QTableWidgetItem*> items = ui->tableWidget_5->selectedItems();
 if(!items.empty()){
    
      int count = items.count();
      QTableWidgetItem *item = items.at(0);
      QString borrow_id= item->text();
      qDebug()<<borrow_id;
  }
  else{
    
      QMessageBox::warning(this," Warning "," Please select a row before operation ");
  }

notes : Judge whether a line is selected ：

QList<QTableWidgetItem*> items = ui->tableWidget_5->selectedItems();
if(!items.empty())
	qDebug()<<" A row is selected ";
else
	QMessageBox::warning(this," Warning "," Please select a row before operation ");
