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 *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
