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. + +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. + +When your client application receives either a XkbIndicatorStateNotify event or +XkbIndicatorMapNotify event, you can note the changes in a changes structure by calling +.I XkbNoteIndicatorChanges. + + +The +.I wanted +parameter is the bitwise inclusive OR of XkbIndicatorMapMask and +XkbIndicatorStateMask. +.I XkbNoteIndicatorChanges +copies any changes reported in +.I new +and specified in +.I wanted +into the changes record specified by +.I old. +.SH STRUCTURES +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 +.I xkb_type +is either XkbIndicatorStateNotify or XkbIndicatorMapNotify, depending on whether the event is +a kbIndicatorStateNotify event or kbIndicatorMapNotify event. +.SH "SEE ALSO" +.BR XkbIndicatorMapMask (__libmansuffix__), +.BR XkbIndicatorStateMask (__libmansuffix__), +.BR XkbSelectEventDetails (__libmansuffix__), +.BR XkbSelectEvents (__libmansuffix__) |
