Understanding MVC in a QAbstractTableModel

I have some data which are represented by a class of my own ; to fix the ideas I give an example.

class MyOwnModel():
  def __init__(self, name="", number=0):
    self.name = name
    self.number = number

I then have a list of such instances, that I want to represent in a QTableView.

li = [MyOwnModel("a", 1), MyOwnModel("b", 2)]

Then I see two strategies to make a QTableView from that :

change MyOwnModel so that it subclasses QAbstractTableModel
build a new QAbstractTableModel which mimics MyOwnModel in a way that its attributes are for instance two QString and connect the dataChanged signal to a function which updates the instance of MyOwnModel

I am not completely satisfied with any of these, but I have no other idea for the moment...

Which one is the most suitable to my problem ? (I have a more complex class in practice but I would like to use the same framework)

As stated in the comment, your model is your list of object. You should subclass QAbstractTableModel to use this list.

Here's my code snippet for this:

import sys
import signal
import PyQt4.QtCore as PCore
import PyQt4.QtGui as PGui

class OneRow(PCore.QObject):
    def __init__(self):
        self.column0="text in column 0"
        self.column1="text in column 1"

class TableModel(PCore.QAbstractTableModel):
    def __init__(self):
        super(TableModel,self).__init__()
        self.myList=[]

    def addRow(self,rowObject):
        row=len(self.myList)
        self.beginInsertRows(PCore.QModelIndex(),row,row)
        self.myList.append(rowObject)
        self.endInsertRows()

    #number of row
    def rowCount(self,QModelIndex):
        return len(self.myList)

    #number of columns
    def columnCount(self,QModelIndex):
        return 2

    #Define what do you print in the cells
    def data(self,index,role):
        row=index.row()
        col=index.column()
        if role==PCore.Qt.DisplayRole:
            if col==0:
                return str( self.myList[row].column0)
            if col==1:
                return str( self.myList[row].column1)

    #Rename the columns
    def headerData(self,section,orientation,role):
        if role==PCore.Qt.DisplayRole:
            if orientation==PCore.Qt.Horizontal:
                if section==0:
                    return str("Column 1")
                elif section==1:
                    return str("Column 2")

if __name__=='__main__':
    PGui.QApplication.setStyle("plastique")
    app=PGui.QApplication(sys.argv)

    #Model
    model=TableModel()
    model.addRow(OneRow())
    model.addRow(OneRow())

    #View
    win=PGui.QTableView()
    win.setModel(model)

    #to be able to close wth ctrl+c
    signal.signal(signal.SIGINT, signal.SIG_DFL)
    #to avoid warning when closing
    win.setAttribute(PCore.Qt.WA_DeleteOnClose)

    win.show()
    sys.exit(app.exec_())

Each element of myList is a row in the table.
