Enumeration Type Documentation

Enumerator
LIBINPUT_CONFIG_ACCEL_PROFILE_NONE 

Placeholder for devices that don't have a configurable pointer acceleration profile.

LIBINPUT_CONFIG_ACCEL_PROFILE_FLAT 

A flat acceleration profile.

Pointer motion is accelerated by a constant (device-specific) factor, depending on the current speed.

See also
libinput_device_config_accel_set_speed
LIBINPUT_CONFIG_ACCEL_PROFILE_ADAPTIVE 

An adaptive acceleration profile.

Pointer acceleration depends on the input speed. This is the default profile for most devices.

Function Documentation

double libinput_event_pointer_get_axis_value_discrete ( struct libinput_event_pointer event,
enum libinput_pointer_axis  axis 
)

Return the axis value in discrete steps for a given axis event.

How a value translates into a discrete step depends on the source.

If the source is LIBINPUT_POINTER_AXIS_SOURCE_WHEEL, the discrete value correspond to the number of physical mouse wheel clicks.

If the source is LIBINPUT_POINTER_AXIS_SOURCE_CONTINUOUS or LIBINPUT_POINTER_AXIS_SOURCE_FINGER, the discrete value is always 0.

Returns
The discrete value for the given event.
