.SH DESCRIPTION
|
|
.LP
|
|
The XkbControlsChangesRec structure allows applications to track modifications
|
|
to an XkbControlsRec
|
|
structure and thereby reduce the amount of traffic sent to the server. The same
|
|
XkbControlsChangesRec
|
|
structure may be used in several successive modifications to the same
|
|
XkbControlsRec structure, then
|
|
subsequently used to cause all of the changes, and only the changes, to be
|
|
propagated to the server.
|
|
|
|
The
|
|
.I changed_ctrls
|
|
field is a mask specifying which logical sets of data in the controls structure
|
|
have been modified. In
|
|
this context, modified means
|
|
.I set,
|
|
that is, if a value is set to the same value it previously contained, it has
|
|
still been modified, and is
|
|
noted as changed. Valid values for
|
|
.I changed_ctrls
|
|
are any combination of the masks listed in Table 1 that have "ok" in the
|
|
.I changed_ctrls
|
|
column. Setting a bit implies the corresponding data fields from the "Relevant
|
|
XkbControlsRec Data
|
|
Fields" column in Table 1 have been modified. The
|
|
.I enabled_ctrls_changes
|
|
field specifies which bits in the
|
|
.I enabled_ctrls
|
|
field have changed. If the number of keyboard groups has changed, the
|
|
.I num_groups_changed
|
|
field is set to True.
|
|
|
|
Table 1 shows the actual values for the individual mask bits used to select
|
|
controls for
|
|
modification and to enable and disable the control. Note that the same mask bit
|
|
is used to
|
|
specify general modifications to the parameters used to configure the control
|
|
(which), and to
|
|
enable and disable the control (enabled_ctrls). The anomalies in the table (no
|
|
"ok" in column)
|
|
are for controls that have no configurable attributes; and for controls that are
|
|
not boolean
|
|
controls and therefore cannot be enabled or disabled.

If you have an Xkb description with controls that have been modified and an
|
|
XkbControlsChangesRec that
|
|
describes the changes that have been made, the
|
|
.I XkbChangeControls
|
|
function provides a flexible method for updating the controls in a server to
|
|
match those in the changed
|
|
keyboard description.
|
|
|
|
.I XkbChangeControls
|
|
copies any controls fields specified by
|
|
.I changes
|
|
from the keyboard description controls structure,
|
|
.I xkb->ctrls,
|
|
to the server specified by
|
|
.I dpy.
