GdkAxisUse

An enumeration describing the way in which a device axis (valuator) maps onto the predefined valuator types that GTK+ understands.

Note that the X and Y axes are not really needed; pointer devices report their location via the x/y members of events regardless. Whether X and Y are present as axes depends on the GDK backend.
