man gii_val_event (Fonctions bibliothèques) - gii_val_event : LibGII valuator events
NAME
gii_val_event : LibGII valuator events
SYNOPSIS
#include <ggi/events.h>
typedef struct {
COMMON_DATA;
uint32 first; /* first valuator reported */ uint32 count; /* number reported */ sint32 value[32]; /* absolute/relative values */
} gii_val_event;
DESCRIPTION
A valuator is a representation of the state of an input device in terms of a physical quantity such as 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
A valuator may be either absolute or relative, like pointer motion events.
To interpret the numbers, query valuator device info with the GII_CMDCODE_GETVALINFO command code.
