A 1 bit in +.I state +turns the corresponding indicator on, a 0 bit turns it off. + +In addition, it can also generate XkbIndicatorStateNotify and +XkbIndicatorMapNotify events. + +Whenever an indicator changes state, the server sends XkbIndicatorStateNotify events +to all interested clients. Similarly, whenever an indicator's map changes, the +server sends XkbIndicatorMapNotify events to all interested clients. + +To receive XkbIndicatorStateNotify events, use +.I XkbSelectEvents +with both the +.I bits_to_change +and +.I values_for_bits +parameters containing XkbIndicatorStateNotifyMask. To receive XkbIndicatorMapNotify +events, use +.I XkbSelectEvents +with XkbIndicatorMapNotifyMask. + +To receive events for only specific indicators, use +.I XkbSelectEventDetails. +Set the +.I event_type +parameter to XkbIndicatorStateNotify or XkbIndicatorMapNotify, and set both the +.I bits_to_change +and +.I values_for_bits +detail parameters to a mask where each bit specifies one indicator, turning on those +bits that specify the indicators for which you want to receive events. + +.I xkb_type +is either XkbIndicatorStateNotify or XkbIndicatorMapNotify, depending on whether the +event is a kbIndicatorStateNotify event or kbIndicatorMapNotify event. + +The +.I changed +parameter is a mask that is the bitwise inclusive OR of the indicators that have +changed. If the event is of type XkbIndicatorMapNotify, +.I changed +reports the maps that changed. If the event is of type XkbIndicatorStateNotify, +.I changed +reports the indicators that have changed state. +.I state +is a mask that specifies the current state of all indicators, whether they have +changed or not, for both XkbIndicatorStateNotify and IndicatorMapNotify events. +.SH STRUCTURES +.LP +.nf + typedef struct _XkbIndicatorChanges { + unsigned int state_changes; + unsigned int map_changes; + }XkbIndicatorChangesRec,*XkbIndicatorChangesPtr; + +.fi +Both types of indicator events use the same structure: + +.nf + 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; + +.fi +.SH DIAGNOSTICS +.TP 15 +.B BadAtom +A name is neither a valid Atom or None +.TP 15 +.B BadImplementation +Invalid reply from server +.SH "SEE ALSO" +.BR XkbIndicatorMapNotify (__libmansuffix__), +.BR XkbIndicatorStateNotify (__libmansuffix__) |
