Usage

#include <ggi/events.h>

Overview

A valuator is a representation of the state of an input device in terms of a physical quantity like length. A valuator event, of type gii_val_event, reports a change in any of those quantities.

Generated events

This structure is used for the evValRelative and evValAbsolute events.

Structure members

typedef struct {
        COMMON_DATA;
        uint32  first;          /* first valuator reported      */
        uint32  count;          /* number reported              */
        sint32  value[32];      /* absolute/relative values     */
} gii_val_event;

A valuator may be either absolute or relative, like pointer motion events.

To interpret the numbers, query valuator device info with GII_CMDCODE_GETVALINFO. [Comment: The documentator has never used these events, but just read the relevant source and header files. Please send any corrections.]
