[PyQt] Memory leak when using QAbstractTableModel

[Noam Raphael]

Hello,

I created a simple program which uses QAbstractTableModel to display a
table with 1000x1000 cells. It works, but if I enlarge the window and
scroll a little bit the memory consumption of the program jumps to the
skies (If I weren't careful, my system would have stuck.)

Here's the program. I'm using PyQt 4.3-2ubuntu7 on Ubuntu 7.10.

==========================
#!/usr/bin/env python

import sys
from PyQt4 import QtCore, QtGui
from PyQt4.QtCore import Qt

class TableModel(QtCore.QAbstractTableModel):
    def rowCount(self, index):
        return 1000

    def columnCount(self, index):
        return 1000

    def data(self, index, role):
        return QtCore.QVariant(str((index.row(), index.column())))

    def headerData(self, col, orientation, role):
        if orientation == Qt.Horizontal and role == Qt.DisplayRole:
            return QtCore.QVariant(str(col))
        if orientation == Qt.Vertical and role == Qt.DisplayRole:
            return QtCore.QVariant(str(col))
        return QtCore.QVariant()


def main():
    app = QtGui.QApplication(sys.argv)

    model = TableModel()
    tableView = QtGui.QTableView()
    tableView.setModel(model)

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

if __name__ == '__main__':
    main()
==========================

Is there some way I can solve this?

Thanks a lot,
Noam
