Enum gdk4::AxisUse[][src]

#[non_exhaustive]
pub enum AxisUse {
Show 13 variants Ignore, X, Y, DeltaX, DeltaY, Pressure, Xtilt, Ytilt, Wheel, Distance, Rotation, Slider, Last, // some variants omitted
}
Expand description

Defines how device axes are interpreted by GTK.

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)

This enum is marked as 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.

DeltaX

the axis is used as the scroll x delta

DeltaY

the axis is used as the scroll y delta

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

Rotation

the axis is used for pen rotation information

Slider

the axis is used for pen slider information

Last

a constant equal to the numerically highest axis value.
