Signal ID
Connect to FocusChanged signal.
Indicates that focus changed on this area. This signal is emitted either as a result of focus handling or event handling.
It's possible that the signal is emitted even if the currently focused renderer did not change, this is because focus may change to the same renderer in the same cell area for a different row of data.
