XkbSAScreen(3) XKB FUNCTIONS XkbSAScreen(3)
NAME
XkbSAScreen - Returns the screenXXX field of act converted to a
signed int
SYNOPSIS
int XkbSAScreen (XkbSwitchScreenAction act);ARGUMENTS
act action from which to extract screen
DESCRIPTION
Actions associated with the XkbSwitchScreen action structure change
the active screen on a multiscreen display.
The
type field of the XkbSwitchScreenAction structure should always
be XkbSA_SwitchScreen.
The
flags field is composed of the bitwise inclusive OR of the masks
shown in Table 1.
Table 1 Switch Screen Action Flags
-------------------------------------------------------------------
Flag Meaning
-------------------------------------------------------------------
XkbSA_SwitchAbsolute 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.
XkbSA_SwitchApplication 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.
The
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
flags field. Xkb provides the
following macros to convert between the integer and signed character
value for screen numbers in XkbSwitchScreenAction structures.
XkbSAScreen macro returns the
screenXXX field of
act converted to a
signed int.
STRUCTURES
typedef struct _XkbSwitchScreenAction {
unsigned char type; /* XkbSA_SwitchScreen */
unsigned char flags; /* controls screen switching */
char screenXXX; /* screen number or delta */
} XkbSwitchScreenAction;
NOTES
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.
