PyQt 4.2 QAbstractTableModel/QTableView Example

from PyQt4.QtCore import *
from PyQt4.QtGui import *
import sys

my_array = [['00','01','02'],

def main():
    app = QApplication(sys.argv)
    w = MyWindow()

class MyWindow(QWidget):
    def __init__(self, *args):
        QWidget.__init__(self, *args)

        tablemodel = MyTableModel(my_array, self)
        tableview = QTableView()

        layout = QVBoxLayout(self)

class MyTableModel(QAbstractTableModel):
    def __init__(self, datain, parent=None, *args):
        QAbstractTableModel.__init__(self, parent, *args)
        self.arraydata = datain

    def rowCount(self, parent):
        return len(self.arraydata)

    def columnCount(self, parent):
        return len(self.arraydata[0])

    def data(self, index, role):
        if not index.isValid():
            return QVariant()
        elif role != Qt.DisplayRole:
            return QVariant()
        return QVariant(self.arraydata[index.row()][index.column()])

Thats great. Now I finally understand how it works. Thanks!

But this fragment doesn't work with the latest stuff:

File "D:\my\py\", line 42, in data return QVariant() TypeError: PyQt4.QtCore.QVariant represents a mapped type and cannot be instantiated

#3 Nader commented on :

Add this to the top of the file to make it run using PyQt version 4.7.3

import sip sip.setapi('QVariant', 1)
