Enum gdk::AxisUse

#[non_exhaustive]pub enum AxisUse {
    Ignore,
    X,
    Y,
    Pressure,
    Xtilt,
    Ytilt,
    Wheel,
    Distance,
    Rotation,
    Slider,
    Last,
    // some variants omitted
}

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.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Ignore

the axis is ignored.

X

the axis is used as the x axis.

Y

the axis is used as the y axis.

Pressure

the axis is used for pressure information.

Xtilt

the axis is used for x tilt information.

Ytilt

the axis is used for y tilt information.

Wheel

the axis is used for wheel information.

Distance

the axis is used for pen/tablet distance information. (Since: 3.22)

Rotation

the axis is used for pen rotation information. (Since: 3.22)

Slider

the axis is used for pen slider information. (Since: 3.22)

Last

a constant equal to the numerically highest axis value.
