QTableView not updated on dataChanged

tuxum

Hello,
I'm not able to update the layout of a QTableView when the Model data is changed.
I tried with dataChanged.emit(index,index), with layoutChanged.emit() and also, as a last resort, with reset(). None of it worked.
My code:

class SettingsDialog(QDialog, settings_design.Ui_settingsDialog):
    def __init__(self):
        super(self.__class__, self).__init__()
        self.setupUi(self)
        self.weekdayTable = QTableView(self.weekdayPage)
        weekdayModel = self.loadMeetingData(self.meetingsData['weekdayList'])
      #weekdayModel.dataChanged.connect(self.updateTable)
        self.weekdayTable.setModel(weekdayModel)
   
    def updateTable(self):
        self.weekdayTable.repaint()

class MeetingsModel(QStandardItemModel):
    def __init__(self, data, columns):
        QStandardItemModel.__init__(self, data, columns)
        with open('meetings.config.json') as f:
            self.meetingsData = json.load(f)

    def setData(self, index, value, other):
               
        self.meetingsData['weekdayList'][int(index.row())][index.column()] = value
        with open('meetings.config.json', 'w+') as f:
            f.write(json.dumps(self.meetingsData))

        self.dataChanged.emit(index, index)
        # self.layoutChanged.emit(index, index)
        return True

What am I doing wrong?

Hi and welcome to devnet,

Something's not clear. Do you have anything that is shown at all ?

In your code excerpt there's nothing related to the handling of the row/column count for example. Also your QTableView doesn't belong to any layout so are you resizing it somewhere ?
