The notify signal is emitted on an object when one of its
properties has been changed. Note that getting this signal
doesn't guarantee that the value of the property has actually
changed, it may also be emitted when the setter for the property
is called to reinstate the previous value.
This signal is typically used to obtain change notification for a
single property.
It is important to note that you must use
canonical parameter names for the property.
