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. +.I XkbSelectEvents +allows you to select or deselect delivery of more than one Xkb +event type at once. Events selected using +.I XkbSelectEvents +are delivered to your program under all circumstances that generate the events. +To restrict delivery of an event to a subset of the conditions under which it +occurs, use +.I XkbSelectEventDetails. XkbSelectEventDetails +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. + +This request changes the Xkb event selection mask for the keyboard specified by +.I device_spec. + +Each Xkb event that can be selected is represented by a bit in the +.I bits_to_change +and +.I values_for_bits +masks. Only the event selection bits specified by the +.I bits_to_change +parameter are affected; any unspecified bits are left unchanged. To turn on +event selection for an event, set the bit for the event in the +.I bits_to_change +parameter and set the corresponding bit in the +.I values_for_bits +parameter. To turn off event selection for an event, set the bit for the event +in the +.I bits_to_change +parameter and do not set the corresponding bit in the +.I values_for_bits +parameter. The valid values for both of these parameters are an inclusive +bitwise OR of the masks shown in Table 1. There is no interface to return your +client's current event selection mask. Clients cannot set other clients' event +selection masks. + +The X server reports the events defined by Xkb to your client application only +if you have requested them via a call to +.I XkbSelectEvents +or +.I XkbSelectEventDetails. +Specify the event types in which you are interested in a mask. + +Table 1 lists the event mask constants that can be specified with the +.I XkbSelectEvents +request and the circumstances in which the mask should be specified. + +.TS +c s s +l l l +l l l. +Table 1 XkbSelectEvents Mask Constants +_ +Event Mask Value Notification Wanted +_ +XkbNewKeyboardNotifyMask (1L<<0) Keyboard geometry change +XkbMapNotifyMask (1L<<1) Keyboard mapping change +XkbStateNotifyMask (1L<<2) Keyboard state change +XkbControlsNotifyMask (1L<<3) Keyboard control change +XkbIndicatorStateNotifyMask (1L<<4) Keyboard indicator state change +XkbIndicatorMapNotifyMask (1L<<5) Keyboard indicator map change +XkbNamesNotifyMask (1L<<6) Keyboard name change +XkbCompatMapNotifyMask (1L<<7) Keyboard compat map change +XkbBellNotifyMask (1L<<8) Bell +XkbActionMessageMask (1L<<9) Action message +XkbAccessXNotifyMask (1L<<10) AccessX features +XkbExtensionDeviceNotifyMask (1L<<11) Extension device +XkbAllEventsMask (0xFFF) All Xkb events +.TE + +If a bit is not set in the +.I bits_to_change +parameter, but the corresponding bit is set in the +.I values_for_bits +parameter, a BadMatch protocol error results.
