Function input_sys::libinput_event_tablet_pad_get_strip_position

pub unsafe extern "C" fn libinput_event_tablet_pad_get_strip_position(
    event: *mut libinput_event_tablet_pad
) -> f64

@ingroup event_tablet_pad

Returns the current position of the strip, normalized to the range [0, 1], with 0 being the top/left-most point in the tablet's current logical orientation.

If the source is @ref LIBINPUT_TABLET_PAD_STRIP_SOURCE_FINGER, libinput sends a terminating event with a ring value of -1 when the finger is lifted from the ring. A caller may use this information to e.g. determine if kinetic scrolling should be triggered.

@note It is an application bug to call this function for events other than @ref LIBINPUT_EVENT_TABLET_PAD_STRIP. For other events, this function returns 0.

@param event The libinput tablet pad event @return The current value of the the axis @retval -1 The finger was lifted
