.SH DESCRIPTION
|
|
.LP
|
|
Actions associated with the XkbSwitchScreen action structure change the active
|
|
screen on a multiscreen display.
|
|
|
|
The
|
|
.I type
|
|
field of the XkbSwitchScreenAction structure should always be
|
|
XkbSA_SwitchScreen.
|
|
|
|
The
|
|
.I flags
|
|
field is composed of the bitwise inclusive OR of the masks shown in Table 1.

|
Flag Meaning
|
|
_
|
|
XkbSA_SwitchAbsolute T{
|
|
If set, the screenXXX field represents the index of the new screen. Otherwise,
|
|
it represents an offset from the current screen to the new screen.
|
|
T}
|
|
XkbSA_SwitchApplication T{
|
|
If not set, the action should switch to another screen on the same server.
|
|
Otherwise, it should switch to another X server or application that shares the
|
|
same physical display.
|
|
T}
|
|
.TE
|
|
|
|
The
|
|
.I screenXXX
|
|
field is a signed character value that represents either the relative or
|
|
absolute screen index, depending on the state of the XkbSA_SwitchAbsolute bit in
|
|
the
|
|
.I flags
|
|
field. Xkb provides the following macros to convert between the integer and
|
|
signed character value for screen numbers in XkbSwitchScreenAction structures.
|
|
|
|
.I XkbSAScreen
|
|
macro returns the
|
|
.I screenXXX
|
|
field of
|
|
.I act
|
|
converted to a signed int.

.SH NOTES
|
|
.LP
|
|
The XkbSwitchScreen action is optional. Servers are free to ignore the action or
|
|
any of its
|
|
flags if they do not support the requested behavior. If the action is ignored,
|
|
it behaves like XkbSA_NoAction. Otherwise, key press and key release events do
|
|
not generate an event.
