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.  Oth-
				 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.

XkbSAPtrDfltValue(3)						   XKB FUNCTIONS					      XkbSAPtrDfltValue(3)

NAME

       XkbSAPtrDfltValue - Returns the valueXXX field of act converted to a signed int

SYNOPSIS

       int XkbSAPtrDfltValue macro ( act )
	     XkbAction act;

ARGUMENTS

       - act  action from which to extract group

DESCRIPTION

       Actions associated with the XkbPtrDfltAction structure change the mk_dflt_btn attribute of the MouseKeys control.

       If the MouseKeys control is not enabled, KeyPress and KeyRelease events are treated as though the action is XkbSA_NoAction. Otherwise, this
       action changes the mk_dflt_btn attribute of the MouseKeys control.

       The type field of the XkbPtrDfltAction structure should always be XkbSA_SetPtrDflt.

       The flags field is composed of the bitwise inclusive OR of the values shown in Table 1 (currently there is only one value defined).

			Table 1 Pointer Default Flags
       -----------------------------------------------------------------
       Flag		       Meaning
       -----------------------------------------------------------------
       XkbSA_DfltBtnAbsolute   If set, the value  field  represents  an
			       absolute  pointer button. Otherwise, the
			       value field represents the amount to  be
			       added to the current default button.

       The affect field specifies what changes as a result of this action. The only valid value for the affect field is XkbSA_AffectDfltBtn.

       The  valueXXX  field  is a signed character that represents the new button value for the mk_dflt_btn attribute of the MouseKeys control. If
       XkbSA_DfltBtnAbsolute is set in flags, valueXXX specifies the button to be used; otherwise, valueXXX specifies the amount to  be  added	to
       the  current  default  button.  In  either case, illegal button choices are wrapped back around into range. Xkb provides macros, to convert
       between the integer and signed character values in XkbPtrDfltAction structures.

       XkbSAPtrDfltValue returns the valueXXX field of act converted to a signed int.

STRUCTURES

	   typedef struct _XkbPtrDfltAction {
	       unsigned char	type;	   /* XkbSA_SetPtrDflt */
	       unsigned char	flags;	   /* controls the pointer button number */
	       unsigned char	affect;    /* XkbSA_AffectDfltBtn */
	       char		valueXXX;  /* new default button member */
	   } XkbPtrDfltAction;
