DESCRIPTION

24       The EnabledControls control is a bit mask where each bit that is turned
25       on  means  the  corresponding  control is enabled, and when turned off,
26       disabled. It corresponds to the enabled_ctrls field of  an  XkbControl‐
27       sRec structure (see STRUCTURES). The bits describing which controls are
28       turned on or off are defined in Table 1.
29
30       Table 1 shows the actual values for the individual mask  bits  used  to
31       select controls for modification and to enable and disable the control.
32       Note that the same mask bit is used to specify general modifications to
33       the parameters used to configure the control (which), and to enable and
34       disable the control (enabled_ctrls). The anomalies  in  the  table  (no
35       "ok"  in column) are for controls that have no configurable attributes;
36       and for controls that are not boolean controls and therefore cannot  be
37       enabled or disabled.

66
67       The mask parameter specifies the boolean controls to be enabled or dis‐
68       abled, and the values mask specifies the new state for those  controls.
69       Valid  values  for both of these masks are composed of a bitwise inclu‐
70       sive OR of bits taken from the set of mask bits in Table 1, using  only
71       those masks with "ok" in the enabled_ctrls column.
72
73       If the X server does not support a compatible version of Xkb or the Xkb
74       extension has not been properly  initialized,  XkbChangeEnabledControls
75       returns  False;  otherwise,  it  sends  the request to the X server and
76       returns True.
77
78       Note that the EnabledControls control only enables  and  disables  con‐
79       trols;  it does not configure them. Some controls, such as the Audible‐
80       Bell control, have no configuration attributes and are therefore manip‐
81       ulated  solely  by  enabling  and disabling them. Others, however, have
82       additional attributes to configure their  behavior.  For  example,  the
83       RepeatControl  control  uses repeat_delay and repeat_interval fields to
84       describe the timing behavior of keys  that  repeat.  The  RepeatControl
85       behavior  is  turned  on  or  off  depending on the value of the XkbRe‐
86       peatKeysMask bit, but you must use other means, as  described  in  this
87       chapter, to configure its behavior in detail.

RETURN VALUES

90       True           The X server supports a compatible version of Xkb.
91
92       False          The  X  server  does not support a compatible version of
93                      Xkb or the Xkb extension has not been properly  initial‐
94                      ized.
