How insert data to qtablewidget row by row - pyqt

Question

I don't understand how to put data into QTableWidget row by row. I take data from lineEdit then put it into table, but when I try to add another person with data it rewrites the previous data, but I need to put it in the row below. I guess I should do something with "row"
Here is my code
from PyQt5 import QtCore, QtGui, QtWidgets
from PyQt5.QtGui import *
import sqlite3
import sys
conn = sqlite3.connect('todo.db')
cur = conn.cursor()
cur.execute('CREATE TABLE if not exists disp_list(disp_name text, disp_surname text, disp_date text)')
conn.commit()
conn.close()

Answer 1

Supposing that you want to insert items incrementally, you should create an instance attribute that will be used to start with the first row (which is 0, not 1, by the way) and then increment it by 1 every time.
This, anyway, should not be done with a file created by pyuic, because those files are meant to be left unmodified. Editing them is highly discouraged and considered bad practice for a lot of reasons. Read more about how to properly use those files when using Designer.
So, rebuild again your .ui file (in the next example I'm supposing you've generated a file named ui_mainwindow.py), and then create your actual script similar to the following:
from PyQt5 import QtCore, QtGui, QtWidgets
from ui_mainwindow import Ui_MainWindow
import sqlite3
import sys
conn = sqlite3.connect('todo.db')
cur = conn.cursor()
cur.execute('CREATE TABLE if not exists disp_list(disp_name text, disp_surname text, disp_date text)')
conn.commit()
conn.close()
class MainWindow(QtWidgets.QMainWindow, Ui_MainWindow):
def __init__(self):
super().__init__()
self.setupUi(self)
self.currentRow = -1
self.pushButton.clicked.connect(self.add_disp)
def add_disp(self):
name = self.lineEdit.text()
surname = self.lineEdit_2.text()
date = self.lineEdit_3.text()
self.currentRow += 1
if self.currentRow > self.tableWidget.rowCount() - 1:
self.tableWidget.insertRow(self.tableWidget.rowCount())
self.tableWidget.setItem(self.currentRow, 0,
QtWidgets.QTableWidgetItem(name))
self.tableWidget.setItem(self.currentRow, 1,
QtWidgets.QTableWidgetItem(surname))
self.tableWidget.setItem(self.currentRow, 2,
QtWidgets.QTableWidgetItem(date))
self.lineEdit.clear()
self.lineEdit_2.clear()
self.lineEdit_3.clear()
if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
mainWindow = MainWindow()
mainWindow.show()
sys.exit(app.exec_())
