[PyQt] On/Off Switch

[Saeed Mahdizadeh Bakhshmand]

Thanks, earlier than seeing your message I managed to use connect and
disconnect functions to be activated while entering On and Off states,
respectively. I used this example
<https://doc.qt.io/archives/4.6/statemachine-twowaybutton.html> to
implement state machine and added:
on.connect('entered()',onApplyButton_connect)
on.connect('exited()',onApplyButton_disconnect)

which ApplyButton_connect  and ApplyButton_disconnect are as following:

  def onApplyButto_connect(self):
   Table.selectionModel().selectionChanged.connect(cellSelected'''#call to
the function that should be carried out on cell selection''')

  def onApplyButton_disconnect(self):
    Table.selectionModel().selectionChanged.disconnect(cellSelected
'''#call to the function that should be carried out on cell selection''')
