XkbSelectEventDetails(3)					   XKB FUNCTIONS					  XkbSelectEventDetails(3)

NAME

       XkbSelectEventDetails  -   Selects  or  deselects for a specific Xkb event and optionally places conditions on when events of that type are
       reported to your client

SYNOPSIS

       Bool XkbSelectEventDetails ( display, device_spec, event_type, bits_to_change, values_for_bits )
	     Display * display;
	     unsigned int device_spec;
	     unsigned int event_type;
	     unsigned long int bits_to_change;
	     unsigned long int values_for_bits;

ARGUMENTS

       display
	      connection to the X server

       device_spec
	      device ID, or XkbUseCoreKbd

       event_type
	      Xkb event type of interest

       bits_to_change
	      determines events to be selected / deselected

       values_for_bits
	      1=>select, 0->deselect; for events in bits_to_change

DESCRIPTION

       Xkb events are selected using an event mask, much the same as normal core X events are selected. However, unlike selecting core	X  events,
       where you must specify the selection status (on or off) for all possible event types whenever you wish to change the selection criteria for
       any one event, Xkb allows you to restrict the specification to only the event types you wish to change. This means that you do not need	to
       remember the event selection values for all possible types each time you want to change one of them.

       Many  Xkb  event  types are generated under several different circumstances. When selecting to receive an Xkb event, you may specify either
       that you want it delivered under all circumstances, or that you want it delivered only for a subset of the possible circumstances.

       You can also deselect an event type that was previously selected for, using the same granularity.

       Xkb provides two functions to select and deselect delivery of Xkb events.  XkbSelectEvents allows you to select	or  deselect  delivery	of
       more than one Xkb event type at once. Events selected using XkbSelectEvents are delivered to your program under all circumstances that gen-
       erate the events.  To restrict delivery of an event to a subset of the conditions under which it occurs, use XkbSelectEventDetails.  XkbSe-
       lectEventDetails  only  allows  you to change the selection conditions for a single event at a time, but it provides a means of fine-tuning
       the conditions under which the event is delivered.

       To select or deselect for a specific Xkb event and optionally place conditions on when events of that type are reported to your client, use
       XkbSelectEventDetails.  This allows you to exercise a finer granularity of control over delivery of Xkb events with XkbSelectEvents.

       While  XkbSelectEvents allows multiple events to be selected, XkbSelectEventDetails changes the selection criteria for a single type of Xkb
       event. The interpretation of the bits_to_change and values_for_bits masks depends on the event type in question.

       XkbSelectEventDetails changes the Xkb event selection mask for the keyboard specified  by  device_spec  and  the  Xkb  event  specified	by
       event_type.   To turn on event selection for an event detail, set the bit for the detail in the bits_to_change parameter and set the corre-
       sponding bit in the values_for_bits parameter. To turn off event detail selection for  a  detail,  set  the  bit  for  the  detail  in  the
       bits_to_change parameter and do not set the corresponding bit in the values_for_bits parameter.

       If an invalid event type is specified, a BadValue protocol error results. If a bit is not set in the bits_to_change parameter, but the cor-
       responding bit is set in the values_for_bits parameter, a BadMatch protocol error results. If  an  undefined  bit  is  set  in  either  the
       bits_to_change or the values_for_bits parameter, a BadValue protocol error results.

       For  each  type	of Xkb event, the legal event details that you can specify in the XkbSelectEventDetails request are listed in the chapters
       that describe each event in detail.

DIAGNOSTICS

       BadMatch       A compatible version of Xkb was not available in the server or an argument has correct type  and	range,	but  is  otherwise
		      invalid

       BadValue       An argument is out of range
