gdk:device-associated-device (object)

object -- a gdk:device object
device -- an associated gdk:device object

The accessor for the associated-device slot of the gdk:device class returns the associated device to device. If the device is of type :master, it will return the paired pointer or keyboard. If the device is of type :slave, it will return the master device to which the device is attached to. If the device is of type :floating, nil will be returned, as there is no associated device.
