How to disable default context menu of QTableView in pyqt?

Question

I am trying to disable a default context menu of QTableView in pyqt.

I have re-implemented the contextMenuEvent but it works on 1st time right click. When I click on the same Item 2nd time the default context menu reappears. (Image attached below for referance.)

I tried "QTableView.setContextMenuPolicy(Qt.NoContextMenu)" but it didn't work. Also referred the answers of similar type questions but still the issue is unresolved.

Any idea?

Ex. showing Re-implemented context menu in QTableView.

def contextMenuEvent(self, event):
    menu = QMenu(self)

    CutAction = QAction(self.view)
    CutAction.setText("&Cut")
    menu.addAction(CutAction)
    CutAction.setIcon(QIcon(":/{0}.png".format("Cut")))
    CutAction.setShortcut("Ctrl+X")
    self.connect(CutAction, SIGNAL("triggered()"), self.cut)

with the code that shows I can not reproduce your problem, even so the solution is to use Qt::CustomContextMenu by enabling the signal customContextMenuRequested, and in the corresponding slot you have to implement the logic:

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


class TableView(QTableView):
    def __init__(self, *args, **kwargs):
        super(TableView, self).__init__(*args, **kwargs)
        self.setContextMenuPolicy(Qt.CustomContextMenu)
        self.customContextMenuRequested.connect(self.onCustomContextMenuRequested)

    def onCustomContextMenuRequested(self, pos):
        menu = QMenu()
        CutAction = menu.addAction("&Cut")
        menu.addAction(CutAction)
        CutAction.setIcon(QIcon(":/{0}.png".format("Cut")))
        CutAction.setShortcut("Ctrl+X")
        CutAction.triggered.connect(self.cut)
        menu.exec_(self.mapToGlobal(pos))

    def cut(self):
        pass


if __name__ == '__main__':
    import sys
    app = QApplication(sys.argv)
    w = TableView()
    model = QStandardItemModel(10, 10, w)
    w.setModel(model)
    w.show()
    sys.exit(app.exec_())
