XkbSASetScreen(3) XKB FUNCTIONS XkbSASetScreen(3)

NAME

XkbSASetScreen - Sets the screenXXX field of act from s

SYNOPSIS

void XkbSASetScreen (XkbSwitchScreenAction act, int s);

ARGUMENTS

act action in which to set screenXXX

s value to set in screenXXX

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.

STRUCTURES

typedef struct _XkbSwitchScreenAction {
unsigned char type; /* XkbSA_SwitchScreen */
unsigned char flags; /* controls screen switching */
char screenXXX; /* screen number or delta */
} XkbSwitchScreenAction;

NOTES

This 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.
