XKB FUNCTIONS XkbNoteControlsChanges(3x11)

NAME

XkbNoteControlsChanges - Notes the changes in a changes

structure when a client receives an XkbControlsNotify event

SYNOPSIS

cc [ flag... ] file... -lX11 [ library... ]

void XkbNoteControlsChanges (XkbControlsChangesPtr changes,

XkbControlsNotifyEvent *new, unsigned int wanted); ARGUMENTS

- changes

records changes indicated by new

- new

tells which things have changed

- wanted

tells which parts of new to record in changes

DESCRIPTION

Whenever a field in the controls structure changes in the

server's keyboard description, the server sends an XkbCon-

trolsNotify event to all interested clients.To receive XkbControlsNotify events under all possible conditions, use XkbSelectEvents and pass XkbControlsNotifyMask in both

bits_to_change and values_for_bits.

To receive XkbControlsNotify events only under certain con-

ditions, use XkbSelectEventDetails using XkbControlsNotify

as the event_type and specifying the desired state changes

in bits_to_change and values_for_bits using mask bits from

Table 1. Table 1 shows the actual values for the individual mask bits used to select controls for modification and to enable and disable the control. Note that the same mask bit is used to

specify general modifications to the parameters used to con-

figure the control (which), and to enable and disable the

control (enabled_ctrls). The anomalies in the table (no "ok"

in column) are for controls that have no configurable attri-

butes; and for controls that are not boolean controls and therefore cannot be enabled or disabled. Table 1 Controls Mask Bits

The changed_ctrls field specifies the controls components

that have changed and consists of bits taken from the masks

defined in Table 1 with "ok" in the changed_ctrls column.

The controls currently enabled in the server are reported in

the enabled_ctrls field. If any controls were just enabled

or disabled (that is, the contents of the enabled_ctrls

field changed), they are flagged in the enabled_ctrl_changes

field. The valid bits for these fields are the masks listed

in Table 1 with "ok" in the enabled_ctrls column. The

num_groups field reports the number of groups bound to the

key belonging to the most number of groups and is automati-

cally updated when the keyboard mapping changes. If the change was caused by a request from a client, the

keycode and event_type fields are set to zero and the

req_major and req_minor fields identify the request. The

req_major value is the same as event_type is set to the type

of event that caused the change (one of KeyPress, KeyRelease, DeviceKeyPress, DeviceKeyRelease, ButtonPress or

ButtonRelease), and req_major and req_minor are undefined.

If event_type is KeyPress, KeyRelease, DeviceKeyPress, or

DeviceKeyRelease, the keycode field is set to the key that

caused the change. If event_type is ButtonPress or Button-

Release, keycode contains the button number. When a client receives an XkbControlsNotify event, it can

note the changes in a changes structure using XkbNoteCon-

trolsChanges. The wanted parameter is a bitwise inclusive OR of bits taken from the set of masks specified in Table 1 with "ok" in the X Version 11 Last change: libX11 1.3.5 2

changed_ctrls column. XkbNoteControlsChanges copies any

changes reported in new and specified in wanted into the changes record specified by old. STRUCTURES The structure for the XkbControlsNotify event is defined as follows: typedef struct { int type; /* Xkb extension base event code */ unsigned long serial; /* X server serial number for event */

Bool send_event; /* True => synthetically generated */

Display * display; /* server connection where event generated */ Time time; /* server time when event generated */

int xkb_type; /* XkbCompatMapNotify */

int device; /* Xkb device ID, will not be XkbUseCoreKbd */

unsigned int changed_ctrls; /* bits indicating which controls data have changed*/

unsigned int enabled_ctrls; /* controls currently enabled in server */

unsigned int enabled_ctrl_changes; /* bits indicating enabled/disabled controls */

int num_groups; /* current number of keyboard groups */

KeyCode keycode; /* != 0 => keycode of key causing change */

char event_type; /* Type of event causing change */

char req_major; /* major event code of event causing change */

char req_minor; /* minor event code of event causing change */

} XkbControlsNotifyEvent;
