A Nstate is a widget which displays one of the state among states defined by user.
This widget inherits from the Button, so that all the functions acting on Button also work for nstate objects.
This widget emits the following signals, besides the ones sent from Button:
"state,changed"- whenever state of nstate is changed
Default content parts of the nstate widget that you can use are the the same that you use with the Button
