XkbSAScreen(3)                                  XKB FUNCTIONS                                 XkbSAScreen(3)



NAME
       XkbSAScreen - Returns the screenXXX field of act converted to a signed int

SYNOPSIS
       int XkbSAScreen ( act )
             XkbSwitchScreenAction act;

ARGUMENTS
       - act  action from which to extract screen

DESCRIPTION
       Actions  associated  with  the  XkbSwitchScreen action structure change the active screen on a multi-screen multiscreen
       screen 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 ------------------------------------------------------------------Flag
       Flag                      Meaning
       -------------------------------------------------------------------XkbSA_SwitchAbsolute ------------------------------------------------------------------XkbSA_SwitchAbsolute
       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.  Oth-erwise, Otherwise,
                                 erwise,  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.
