XkbActionCtrls(3)						   XKB FUNCTIONS						 XkbActionCtrls(3)

NAME

       XkbActionCtrls - Returns the ctrls fields of act converted to an unsigned int

SYNOPSIS

       unsigned int XkbActionCtrls (XkbCtrlsAction act);

ARGUMENTS

       - act  action from which to extract controls

DESCRIPTION

       Actions associated with the XkbCtrlsAction structure change the state of the boolean controls.

       The type field can have any one of the values shown in Table 1.

		       Table 1 Controls Action Types
       --------------------------------------------------------------
       Type		    Effect
       --------------------------------------------------------------
       XkbSA_SetControls    A key press enables any boolean controls
			    specified in the ctrls fields that	were
			    not  already  enabled at the time of the
			    key press.	A key release  disables  any
			    controls enabled by the key press.	This
			    action   can   cause   XkbControlsNotify
			    events.
       XkbSA_LockControls   If	the  XkbSA_LockNoLock bit is not set
			    in the flags field, a key press  enables
			    any  controls  specified  in  the  ctrls
			    fields that were not already enabled  at
			    the time of the key press.
			    If the XkbSA_LockNoUnlock bit is not set
			    in the flags field, a key  release	dis-
			    ables  any	controls  specified  in  the
			    ctrls fields that were not already	dis-
			    abled at the time of the key press.
			    This  action can cause XkbControlsNotify
			    events.

       The flags field is composed of the bitwise inclusive OR of the masks shown in Table 2.

		       Table 2 Control Action Flags
       --------------------------------------------------------------
       Flag		    Meaning
       --------------------------------------------------------------
       XkbSA_LockNoLock     If	set,  and   the   action   type   is
			    XkbSA_LockControls, the server only dis-
			    ables controls.
       XkbSA_LockNoUnlock   If	set,  and   the   action   type   is
			    XkbSA_LockControls,   the	server	only
			    enables controls.

       The XkbSA_SetControls action implements a key that enables a boolean control when pressed and disables it when released. The XkbSA_LockCon-
       trols  action  is  used to implement a key that toggles the state of a boolean control each time it is pressed and released. The XkbSA_Loc-
       kNoLock and XkbSA_LockNoUnlock flags allow modifying the toggling behavior to only unlock or only lock the boolean control.

       The ctrls0, ctrls1, ctrls2, and ctrls3 fields represent the boolean controls in the enabled_ctrls field	of  the  controls  structure.  Xkb
       macros, to convert between the two formats.

       XkbActionCtrls returns the ctrls fields of act converted to an unsigned int.

STRUCTURES

	   typedef struct _XkbCtrlsAction {
	       unsigned char	type;	 /* XkbSA_SetControls, XkbSA_LockControls */
	       unsigned char	flags;	 /* with type, controls enabling and disabling
       of controls */
	       unsigned char	ctrls3;  /* ctrls0 through ctrls3 represent the boolean
       controls */
	       unsigned char	ctrls2;  /* ctrls0 through ctrls3 represent the boolean
       controls */
	       unsigned char	ctrls1;  /* ctrls0 through ctrls3 represent the boolean
       controls */
	       unsigned char	ctrls0;  /* ctrls0 through ctrls3 represent the boolean
       controls */
	   } XkbCtrlsAction;

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 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.
