.TH XkbSAScreen __libmansuffix__ __xorgversion__ "XKB FUNCTIONS"
.SH NAME
XkbSAScreen \- Returns the screenXXX field of act converted to a signed int
.SH SYNOPSIS
.B int XkbSAScreen
(
.I act
)
.br
XkbSwitchScreenAction \fIact\fP\^;
.if n .ti +5n
.if t .ti +.5i
.SH ARGUMENTS
.TP
.I \- act
action from which to extract screen
.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.
.TS
c s
l l
l lw(4i).
Table 1 Switch Screen Action Flags
_
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 STRUCTURES
.LP
.nf
typedef struct _XkbSwitchScreenAction {
unsigned char type; /\(** XkbSA_SwitchScreen */
unsigned char flags; /\(** controls screen switching */
char screenXXX; /\(** screen number or delta */
} XkbSwitchScreenAction;
.fi
.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.
