DeviceManager.addOnDeviceChanged

The ::device-changed signal is emitted whenever a device has changed in the hierarchy, either slave devices being disconnected from their master device or connected to another one, or master devices being added or removed a slave device.

If a slave device is detached from all master devices (Device.getAssociatedDevice returns NULL), its GdkDeviceType will change to GDK_DEVICE_TYPE_FLOATING, if it's attached, it will change to GDK_DEVICE_TYPE_SLAVE.
