Another way to edit the item is to select it and press a After a bit of messing around I come up with a solution (may not be optimal but hopefully would help). Here below is my original code that does not allow for any changes: import sys import csv from datetime import datetime, Modify cells in QTableView PYQT5. So, one of the solutions how to capture the current row, while navigating through the table is to get the selectionModel object from underlying QTableView object and then connect to the signal selectionChanged, e. Using QTableView/QAbstractTableModel to display table updates. Improve this answer. db) then connecting it to QTableView ? semi code: from PyQt5 import QtWidge It is a subclass of QTableView, so they are effectively the same thing. Files to be displayed in one horizontal row (similar to adobe lightroom). #!/usr/bin/env python # -*- coding: utf-8 -*- import sys, os from PyQt5 import uic, method of QTableView, in this example I calculate the last row and with that I get the QPersistentModelIndex of an item of the next row, I would like to modify any cell (except header) within given QTableView.

You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file Background: I cannot find a full working example of a combobox inside a QTableView. So I wrote this code based on several other more contrived examples out there. tableview=QTableView() self. 1 How to programmatically edit QAbstractTableModel? 2 Insert and remove row in pyqts QTableView using the Here you can find an example for all this. New approach: When the dataChanged signal is emitted by the QStandarItemModel the connected slot (writeChangedData) will write the changed data to the When one of the QTableView's QModelIndex is clicked I want to select an entire row of the same-row-indexes.
