How to get the row of a ButtonWidget in a QTableWidget?

Question

I'm trying to dynamically fill a QTableWidget (table_proj).

It works so far that the Table is filled and it looks right. The Code for the items in the Table:

for row in range(nb_row):
   for col in range(nb_col):
       item = QtWidgets.QTableWidgetItem(str(data[row][col]))
       self.table_proj.setItem(row, 0, item)
       self.table_proj.setCellWidget(row, 1, EditButtonWidget())

Where the nb_col is always two, and the nb_row is the len(data). Data is the dictionary that gets all the information.

The result looks like:

The Code for the EditButton's looks like:

class EditButtonWidget(QtWidgets.QWidget):
    
    def __init__(self, parent=None):
        super(EditButtonWidget,self).__init__(parent)

        ###

        self.dw = DockWidget()

        ###Layout###

        self.layout = QtWidgets.QHBoxLayout(self)

        self.layout.setContentsMargins(0,0,0,0)
        self.layout.setSpacing(0)

        self.b1 = QtWidgets.QPushButton()
        self.b1.setText('Webseite')
        self.b1.clicked.connect(self.doButtonB1)


        self.b2 = QtWidgets.QPushButton()
        self.b2.setText('Link kopieren')
        self.b2.clicked.connect(self.doButtonB2)

        self.layout.addWidget(self.b1)
        self.layout.addWidget(self.b2)


        self.setLayout(self.layout)


    def doButtonB1(self):

        row = self.dw.table_proj.currentRow()
        print(row)
        

    def doButtonB2(self):
        
        pass

My problem is, that when I click on the Button "Webseite" it doesn't give me the correct row, but instead i just receive -1.

So if someone could give me a hint, where my mistake is, that would be great.

Just make the row a member of the EditButtonWidget class as suggested on the Qt forum here .

For example:

class EditButtonWidget(QtWidgets.QWidget):
    
    def __init__(self, row, parent=None):
        super(EditButtonWidget,self).__init__(parent)

        self.row = row

        ### etc ...

    def doButtonB1(self):
        print(self.row)

and

for row in range(nb_row):
   for col in range(nb_col):
       item = QtWidgets.QTableWidgetItem(str(data[row][col]))
       self.table_proj.setItem(row, 0, item)
       self.table_proj.setCellWidget(row, 1, EditButtonWidget(row))

This might not work if you allow users to insert/delete/move rows. In that case you probably need to use indexAt as in the qt forum post or pass more information (in your case the website url) to the EditButtonWidget .
