Answer 1

I finally implemented it this way!!

def contextMenuEvent(self, pos):
    if self.selectionModel().selection().indexes():
        for i in self.selectionModel().selection().indexes():
            row, column = i.row(), i.column()
        menu = QtGui.QMenu()
        openAction = menu.addAction("Open")
        deleAction = menu.addAction("Delete")
        renaAction = menu.addAction("Rename")
        action = menu.exec_(self.mapToGlobal(pos))
        if action ==openAction:
            self.openAction(row, column)

def openAction(self, row, column):
    if self._slideShowWin:
        self._slideShowWin.showImageByPath(self._twoDLst[row][column])
        self._animateUpOpen()

def deleteSelected(self):
    # TODO
    pass

that works like a charm !!!

Answer 2

QTableView has contextMenuEvent() event, to show a right-click menu:

• Create a QMenu inside this event
• Add some QActions to QMenu
• connect each QAction to slots using triggered signal of QAction
• call popup(QCursor.pos()) on QMenu

When user right-click the tableView the cell under the mouse pointer will be selected and at the same time a menu will appear. When user selects an action on the menu, the connected slot will be called, get the selected cell of tabel in this slot and perform the required action on this cell.

...
def contextMenuEvent(self, event):
    self.menu = QtGui.QMenu(self)
    renameAction = QtGui.QAction('Rename', self)
    renameAction.triggered.connect(lambda: self.renameSlot(event))
    self.menu.addAction(renameAction)
    # add other required actions
    self.menu.popup(QtGui.QCursor.pos())
    ...

def renameSlot(self, event):
    print "renaming slot called"
    # get the selected row and column
    row = self.tableWidget.rowAt(event.pos().y())
    col = self.tableWidget.columnAt(event.pos().x())
    # get the selected cell
    cell = self.tableWidget.item(row, col)
    # get the text inside selected cell (if any)
    cellText = cell.text()
    # get the widget inside selected cell (if any)
    widget = self.tableWidget.cellWidget(row, col)
...
