Display TABLE with QTableWidget

provopoulos3720 | 2020-05-22 00:27:12 UTC | #1

Greetings here, I'm learning QT for Python to use for a University project as well as some personal endeavors. I'm using a cursor to query data from various tables and here's what I've got:

cursor = cnx.cursor()
query = ("SELECT * FROM Flight")
cursor.execute(query)
records = cursor.fetchall()

If I try to print(records) I receive the following list: [('GR001', 'ZTH', datetime.datetime(2020, 8, 9, 9, 25), 'PRG', datetime.datetime(2020, 8, 9, 10, 55), 'SX-DNH'), ('GR002', 'PRG', datetime.datetime(2020, 8, 9, 18, 30), 'CFU', datetime.datetime(2020, 8, 9, 21, 40), 'SX-DNH'), ('GR003', 'CFU', datetime.datetime(2020, 7, 12, 9, 0), 'EFL', datetime.datetime(2020, 7, 12, 9, 20), 'SX-DGA'), ('GR004', 'CFU', datetime.datetime(2020, 8, 15, 11, 30), 'ZTH', datetime.datetime(2020, 8, 15, 12, 0), 'SX-DGF'), ('GR005', 'EFL', datetime.datetime(2020, 8, 20, 18, 5), 'ZTH', datetime.datetime(2020, 8, 20, 18, 30), 'SX-DVI'), ('GR006', 'EFL', datetime.datetime(2020, 9, 2, 14, 30), 'CFU', datetime.datetime(2020, 9, 2, 14, 50), 'SX-DNF'), ('GR007', 'ZTH', datetime.datetime(2020, 10, 7, 13, 40), 'EFL', datetime.datetime(2020, 10, 7, 14, 5), 'SX-DGA'), ('GR008', 'ZTH', datetime.datetime(2020, 4, 21, 15, 5), 'CFU', datetime.datetime(2020, 4, 21, 15, 35), 'SX-DVI'), ('GR009', 'EFL', datetime.datetime(2020, 7, 22, 14, 30), 'CFU', datetime.datetime(2020, 7, 22, 14, 50), 'SX-DNF')]

I want to display those results with QTableWidget/QTableView or whichever widget would work best for my case. I'll have to do this multiple times for different tables each time. Closest solution I've found for this problem is this SO question: https://stackoverflow.com/questions/54691624/load-qtablewidget-with-a-list

What I want to achieve is preferably a button inside MainWindow that once pushed, the queried data will be displayed. Here's how my PyQT5 code is structured:

class MainWindow(QtWidgets.QMainWindow):
    def __init__(self, parent=None):
        super().__init__(parent)
        self.setWindowIcon(QIcon('ico.png'))
        self.setFixedSize(800, 600)

if __name__ == '__main__':
    app = QtWidgets.QApplication(sys.argv)
    login = Login()
    if login.exec_() == QtWidgets.QDialog.Accepted:
        window = MainWindow()
        window.show()
        sys.exit(app.exec_())

Any help would be greatly appreciated!
