[PyKDE] PyQt4 Segmentation Fault - QTableView

[Chris Dunscombe]

Hi,

I now have a simple script to demo the seg fault:

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

class mainWindow(QMainWindow):
    def __init__(self, parent = None):
        QMainWindow.__init__(self, parent)
        self.centralWidget = QWidget()
        self.setCentralWidget(self.centralWidget)

        model = QStandardItemModel(4, 2)
        tableView = QTableView()
        tableView.setModel(model)

        for row in range(4):
            for column in range(2):
                index = model.index(row, column, QModelIndex())
                model.setData(index,QVariant("Text"))
        txtWidget1 = QTextEdit()
        txtWidget2 = QTextEdit()
        tabWidget = QTableWidget(2,2)
        vLayout = QVBoxLayout()
        vLayout.addWidget(txtWidget1)
        vLayout.addWidget(txtWidget2)
        vLayout.addWidget(tabWidget)
        vLayout.addWidget(tableView)
        self.centralWidget.setLayout(vLayout)

app = QApplication(sys.argv)
mw = mainWindow()
mw.show()
app.exec_()


This seg faults when you click in the QTableView, bottom of the window, also it doesn't properly
display the table. As you can see from the code it works fine with a QTableWidget.

The issue I have in my app is a fair bit more complicated but essentially it all seems to revolve
around displaying a QTableView within a layout  etc in a QMainWindow.

Thanks,

Chris
