Checking which checkbox checked on QTableWidget

[Nightmaster]

Hi everyone

I am having an issue with checking which checkbox has been chosen on a QTableWidget.

The purpose of the table is to display a list of available appointments, a checkbox (variable cb) is added to the last column of each row for a user to check. The table can also filter the appointments by date (appt_date_filter method). I had to add a new instance of checkbox for this (cb1) to get this working.

There is a submit button which isn't working when the table is filtered. When the button is clicked it triggers a method called "submitted".

The following error occrus : self.checkboxclicked = self.cb.sender()
RuntimeError: wrapped C/C++ object of type QCheckBox has been deleted

I guess when the appointments are filtered cb gets deleted as cb1 is being used?

Also i notice that if self.cb.isChecked(): returns false even when a cb is checked.

Full code below:

self.table = QtWidgets.QTableWidget(self)
        self.table.setGeometry(QtCore.QRect(50, 150, 700, 505))
        self.submit_btn = QtWidgets.QPushButton(self)
        self.submit_btn.setGeometry(QtCore.QRect(350,675,75,45))
        self.submit_btn.setText("Submit")
        self.table.show()
        self.tab_row = 0
        #print(self.get_appts)



        self.qb = QButtonGroup(self.table)
        for self.data in self.get_appts:
            self.table.setRowCount(len(self.get_appts))
            self.table.setColumnCount(len(self.get_appts[0]))
            self.table.setItem(self.tab_row, 0, QTableWidgetItem(self.data[0]))
            self.table.setItem(self.tab_row, 1,QTableWidgetItem(self.data[1]))
            self.table.setItem(self.tab_row, 2, QTableWidgetItem(self.data[2]))
            self.table.setItem(self.tab_row, 3, QTableWidgetItem(self.data[3]))
            self.table.setHorizontalHeaderLabels(["Start Time", "End Time", "Location", "Doctor", "Select one"])
            self.table.setColumnWidth(0, 160)
            self.table.setColumnWidth(1,160)
            self.table.setColumnWidth(2,120)
            self.table.setColumnWidth(3, 140)

            self.cb = QCheckBox(self.table)
            #self.check_item = (QTableWidgetItem(QtCore.Qt.ItemIsUserCheckable | QtCore.Qt.ItemIsEnabled))
            #self.check_item.setCheckState(QtCore.Qt.Unchecked)

            self.cb.show()
            self.qb.addButton(self.cb)
            self.table.setCellWidget(self.tab_row, 4, self.cb)

            if self.cb.isChecked():
                print("yes it is checked")
            self.cb.clicked.connect(self.change)
            self.tab_row += 1

            self.date_picker.dateChanged.connect(self.appt_date_filter)
            self.table.cellClicked.connect(self.change)
            self.submit_btn.clicked.connect(self.submitted)

        print(self.filter_date_string, "filter date")

        self.get_filt_apps = main.filter_appts(self.filter_date_string)

            self.table.setItem(self.tab_row1, 1,QTableWidgetItem(filt_data[1]))
            self.table.setItem(self.tab_row1, 2, QTableWidgetItem(filt_data[2]))
            self.table.setItem(self.tab_row1, 3, QTableWidgetItem(filt_data[3]))

            self.cb1 = QCheckBox(self.table)

            self.cb1.show()
            self.qb.addButton(self.cb1)
            self.table.setCellWidget(self.tab_row1, 4, self.cb1)

Hi,

Don't use widgets for that. They are for static content and do not have any link with the model below.

Make that item checkable. It will show a checkbox and you'll be have the information in your model.

Thanks @SGaist. I changed it to QTableView and ditched the checkboxes. Selecting rows works fine.
