Signal ID
Connect to SelectionChanged signal.
Emitted when the selection state of some of the items in model changes.
Note that this signal does not specify the new selection state of the items, they need to be queried manually. It is also not necessary for a model to change the selection state of any of the items in the selection model, though it would be rather useless to emit such a signal.
