How To Get Selected Items From Qcombobox To Be Displayed In Qtablewidget In Pyqt5? (qcombobox Has Checkbox To Pick Items)

I have QTableWidget in which I have QComboBox in each row for particular column. My each QCombobox has multiple values with checkboxes. I want to display selected item/s from each

Solution 1:

You should find a way to keep track of the row for each combo model, so that you can set the item text accordingly.

Note that I changed your code logic a bit, as there were some conceptual mistakes:

• don't set instance attributes if they are not required: all those self.rowPosition, self.monthList, etc, change everytime the for loop cycles, and you don't need them after that;
• avoid using uppercase names for variables and functions
• the month list is always the same, build it before the for cycle instead of computing it each time
• instead of setting the model to the combo in the function, make it return the model

Edit: added copy function after comment request

defcreateModel(options):
    model = QStandardItemModel(len(options), 1)
    firstItem = QtGui.QStandardItem("SelectMonths")
    firstItem.setBackground(QtGui.QBrush(QtGui.QColor(200, 200, 200)))
    firstItem.setSelectable(False)
    model.setItem(0, 0, firstItem)
    for i, area inenumerate(options):
        item = QStandardItem(area)
        item.setFlags(Qt.ItemIsUserCheckable | Qt.ItemIsEnabled)
        item.setData(Qt.Unchecked, Qt.CheckStateRole)
        model.setItem(i+1, 0, item)
    return model

classDemoCode(QtWidgets.QMainWindow, Ui_MainWindow):                    
    def__init__(self):
        super(DemoCode, self).__init__()
        self.setupUi(self)  

        monthList = [(date.today() + relativedelta(months=-n)).strftime('1-%b-%Y') for n inrange(1, 5)]
        self.models = {}

        rows = self.tableWidget.rowCount()
        for row inrange(rows, rows + 3):
            self.tableWidget.insertRow(row)
            comboBox = QtWidgets.QComboBox()
            model = createModel(monthList)
            comboBox.setModel(model)
            model.itemChanged.connect(lambda _, row=row: self.on_itemChanged(row))
            self.models[row] = model
            self.tableWidget.setCellWidget(row, 0, comboBox)
            item = QTableWidgetItem()
            self.tableWidget.setItem(row, 1, item)

        self.tableWidget.setColumnWidth(1,150)

    defon_itemChanged(self, tableRow):
        model = self.models[tableRow]
        items = []
        for row inrange(model.rowCount()):
            comboItem = model.index(row, 0)
            if comboItem.data(Qt.CheckStateRole):
                items.append(comboItem.data())
        self.tableWidget.item(tableRow, 1).setText(', '.join(items))

    defcopyFromRow(self, tableRow):
        sourceModel = self.models[tableRow]
        checkedRows = []
        for row inrange(sourceModel.rowCount()):
            if sourceModel.index(row, 0).data(Qt.CheckStateRole):
                checkedRows.append(row)
        for model in self.models.values():
            if model == sourceModel:
                continuefor row inrange(model.rowCount()):
                model.setData(
                    model.index(row, 0), 
                    Qt.Checked if row in checkedRows else Qt.Unchecked, 
                    Qt.CheckStateRole)

I'd also suggest to remove the "Select Months" and "Selected Months" items, and use them as table headers.
