.SH DESCRIPTION
|
|
.LP
|
|
Xkb also allows applications to refer to indicators by name. Use
|
|
.I XkbGetNames
|
|
to get the indicator names. Using names eliminates the need for hard-coding
|
|
bitmask values for particular keyboards. For example, instead of using
|
|
vendor-specific constants such as WSKBLed_ScrollLock mask on Digital
|
|
workstations or XLED_SCROLL_LOCK on Sun workstations, you can instead use
|
|
.I XkbGetNamedDeviceIndicator
|
|
to look up information on the indicator named "Scroll Lock."
|
|
|
|
If the device specified by
|
|
.I device_spec
|
|
has an indicator named
|
|
.IR name ", " XkbGetNamedDeviceIndicator
|
|
returns True and populates the rest of the parameters with information about the
|
|
indicator. Otherwise,
|
|
.I XkbGetNamedDeviceIndicator
|
|
returns False.
|
|
|
|
The
|
|
.I ndx_rtrn
|
|
field returns the zero-based index of the named indicator. This index is the bit
|
|
position to use in any function call that requires a mask of indicator bits, as
|
|
well as the indicator's index into the XkbIndicatorRec array of indicator maps.
|
|
.I state_rtrn
|
|
returns the current state of the named indicator (True = on, False = off).
|
|
.I map_rtrn
|
|
returns the indicator map for the named indicator. In addition, if the indicator
|
|
is mapped to a physical LED, the
|
|
.I real_rtrn
|
|
parameter is set to True.
|
|
|
|
Each of the "
|
|
.I _rtrn
|
|
" arguments is optional; you can pass NULL for any unneeded "
|
|
.I _rtrn
|
|
" arguments.
|
|
|
|

.I XkbGetNamedIndicator
|
