.SH DESCRIPTION
|
|
.LP
|
|
There are two ways to make changes to map components: either change a local copy
|
|
of the keyboard map and
|
|
call
|
|
.I XkbSetMap
|
|
to send the modified map to the server, or, to reduce network traffic, use an
|
|
XkbMapChangesRec structure
|
|
and call
|
|
.I XkbChangeMap.
|
|
|
|
Use
|
|
.I XkbSetMap
|
|
to send a complete new set of values for entire components (for example, all
|
|
symbols, all actions, and so
|
|
on) to the server. The
|
|
.I which
|
|
parameter specifies the components to be sent to the server, and is a bitwise
|
|
inclusive OR of the masks
|
|
listed in Table 1. The
|
|
.I xkb
|
|
parameter is a pointer to an XkbDescRec structure and contains the information
|
|
to be copied to the server.
|
|
For each bit set in the
|
|
.I which
|
|
parameter,
|
|
.I XkbSetMap
|
|
takes the corresponding structure values from the
|
|
.I xkb
|
|
parameter and sends it to the server specified by
|
|
.I dpy.
|
|
|
|
If any components specified by
|
|
.I which
|
|
are not present in the
|
|
.I xkb
|
|
parameter,
|
|
.I XkbSetMap
|
|
returns False. Otherwise, it sends the update request to the server and returns
|
|
True.
|
|
.I XkbSetMap
|
|
can generate BadAlloc, BadLength, and BadValue protocol errors.
|
|
|
|
Key types, symbol maps, and actions are all interrelated; changes in one require
|
|
changes in the others. Xkb
|
|
provides functions to make it easier to edit these components and handle the
|
|
interdependencies. Table 1
|
|
lists these helper functions and provides a pointer to where they are defined.

field identifies the map components that have changed in an XkbDescRec structure
|
|
and may contain any of the

bits in Table 1, which are also shown in Table 2. Every 1 bit in
|
|
.I changed

also identifies which other fields in the XkbMapChangesRec structure contain

valid values, as indicated in

|
Table 2. The

by the server whenever it returns the data for an XkbMapChangesRec.

The
|
|
.I display
|
|
field points to an X display structure. The
|
|
.I flags field is private to the library: modifying
|
|
.I flags
|
|
may yield unpredictable results. The
|
|
.I device_spec
|
|
field specifies the device identifier of the keyboard input device, or
|
|
XkbUseCoreKeyboard, which specifies the core keyboard device. The
|
|
.I min_key_code
|
|
and
|
|
.I max_key_code
|
|
fields specify the least and greatest keycode that can be returned by the
|
|
keyboard.
|
|
|
|
Each structure component has a corresponding mask bit that is used in function
|
|
calls to
|
|
indicate that the structure should be manipulated in some manner, such as
|
|
allocating it
|
|
or freeing it. These masks and their relationships to the fields in the
|
|
XkbDescRec are

shown in Table 3.
