how to make a cell in a QTableWidget read only?

Question

i have the following code defining the gui of my app

class Ui (object):
    def setupUi():
        self.tableName = QtGui.QTableWidget(self.layoutWidget_20)
        self.tableName.setObjectName(_fromUtf8("twHistoricoDisciplinas"))
        self.tableName.setColumnCount(4)
        self.tableName.setRowCount(3)

and the following code in my app

class MainWindow(QtGui.QMainWindow):
    def __init__(self):
        self.ui = Ui()
        self.ui.setupUi(self)
        self.createtable()

    #creating a tw cell
    def cell(self,var=""):
            item = QtGui.QTableWidgetItem()
            item.setText(var)
            return item

    def createtable(self):
         rows = self.tableName.rowCount()
         columns = self.tableName.columnCount()
         for i in range(rows):
             for j in range(columns):
                 item = self.cell("text")
                 self.ui.tableName.setItem(i, j, item)

I want to be able to add new rows and columns and edit them but i want to lock some of the cells. ( i already have code that expand the table ) how can i make some cells read only while keeping the others read write? i found this link How to make a column in QTableWidget read only? with a solution for the problem in C++, is python solution similar ?

EDIT: Removed the answer from the post and pasted as an answer

Answer 1

The editing status of a QTableWidgetItem is never entered when there are no Edit Triggers:

self.tableName.setEditTriggers(QtGui.QAbstractItemView.NoEditTriggers)

Answer 2

Like Sven Krüger's answer, you can also use this methods for PyQt5:

self.tableWidget.setEditTriggers(QtWidgets.QTableWidget.NoEditTriggers)

Answer 3

If you want the UI to look the same (have it still selectable, and turn blue, but just not editable) I found QtCore.Qt.ItemIsEditable gave good results.

item = QtWidgets.QTableWidgetItem()
item.setFlags(item.flags() ^ QtCore.Qt.ItemIsEditable)
self.table_widget.setItem(row, column, item)

Answer 4

For PyQt6, it's the same as @ozcanyarimdunya but with the enum EditTrigger:

self.tableWidget.setEditTriggers(QTableWidget.EditTrigger.NoEditTriggers)
