how to make a cell in a QTableWidget read only?

i have the following code defining the gui of my app

class Ui (object):
    def setupUi():
        self.tableName = QtGui.QTableWidget(self.layoutWidget_20)
   开发者_JS百科     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

I played a little with the code and read some more documentation the answer to the problem is

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")
             # execute the line below to every item you need locked
             item.setFlags(QtCore.Qt.ItemIsEnabled)
             self.ui.tableName.setItem(i, j, item)

The solution is the line "item.setFlags(QtCore.Qt.ItemIsEnabled)", you use it to set the cell property QtCore.Qt.ItemIsEnabled to disabled, so you can't select or edit the cell

You can change a number of other properties this way at runtime as per documentarion on http://doc.qt.io/archives/qt-4.8/qt.html under the section Qt::ItemFlag

as mentioned in a comment by Sven on the second answer to this question, if you have a static number of rows and columns in your QTableWidgetItem you can select the properties of the cells with Qtdesigner if you use it to create the screens for your application

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

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

---

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

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

---

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)

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

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