XKB FUNCTIONS                       XkbNoteIndicatorChanges(3x11)



NAME
     XkbNoteIndicatorChanges - Notes the  changes  in  a  changes
     structure

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

     void  XkbNoteIndicatorChanges  (XkbIndicatorChangesPtr  old,
          XkbIndicatorNotifyEvent *new, unsigned int wanted);

ARGUMENTS
     - old
          XkbIndicatorChanges structure to be updated

     - new
          event from which changes are to be copied

     - wanted
          which changes are to be noted

DESCRIPTION
     Whenever an indicator changes state, the server sends XkbIn-
     dicatorStateNotify  events  to all interested clients. Simi-
     larly, whenever an indicator's map changes, the server sends
     XkbIndicatorMapNotify events to all interested clients.

     To receive  XkbIndicatorStateNotify  events,  use  XkbSelec-
     tEvents  with  both  the  bits_to_change and values_for_bits
     parameters   containing   XkbIndicatorStateNotifyMask.    To
     receive  XkbIndicatorMapNotify  events,  use XkbSelectEvents
     with XkbIndicatorMapNotifyMask.

     To  receive  events  for  only  specific   indicators,   use
     XkbSelectEventDetails.   Set  the  event_type  parameter  to
     XkbIndicatorStateNotify or  XkbIndicatorMapNotify,  and  set
     both  the  bits_to_change and values_for_bits detail parame-
     ters to a mask where each bit specifies one indicator, turn-
     ing  on those bits that specify the indicators for which you
     want to receive events.

     The  changed  parameter  is  a  mask  that  is  the  bitwise
     inclusive  OR  of  the  indicators that have changed. If the
     event is of type XkbIndicatorMapNotify, changed reports  the
     maps  that changed. If the event is of type XkbIndicatorSta-
     teNotify, changed reports the indicators that  have  changed
     state.  state  is a mask that specifies the current state of
     all indicators, whether they have changed or not,  for  both
     XkbIndicatorStateNotify and IndicatorMapNotify events.

     When your client application receives  either  a  XkbIndica-
     torStateNotify event or XkbIndicatorMapNotify event, you can
     note  the  changes  in  a  changes  structure   by   calling

XKB FUNCTIONS                       XkbNoteIndicatorChanges(3x11)



     XkbNoteIndicatorChanges.


     The wanted parameter is the bitwise inclusive OR of XkbIndi-
     catorMapMask  and  XkbIndicatorStateMask.  XkbNoteIndicator-
     Changes copies any changes reported in new and specified  in
     wanted into the changes record specified by old.

STRUCTURES
     Both types of indicator events use the same structure:

     typedef struct _XkbIndicatorNotify {
       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;   /* specifies state or map notify */
       int            device;     /* Xkb device ID, will not be XkbUseCoreKbd */
       unsigned int   changed;    /* mask of indicators with new state or map */
       unsigned int   state;      /* current state of all indicators */
     } XkbIndicatorNotifyEvent;

     xkb_type is either XkbIndicatorStateNotify or  XkbIndicator-
     MapNotify,  depending  on  whether  the event is a kbIndica-
     torStateNotify event or kbIndicatorMapNotify event.
