NAME

       XkbPtrActionX  -  Returns  the  high_XXX  and  low_XXX  fields  of  act
       converted to a signed int

SYNOPSIS

       int XkbPtrActionX (XkbPtrAction act);

ARGUMENTS

       - act  action from which to extract X

DESCRIPTION

       Actions associated with the XkbPtrAction  structure  move  the  pointer
       when keys are pressed and released.

       If the MouseKeys control is not enabled, KeyPress and KeyRelease events
       are treated as though the action is XkbSA_NoAction.

       If  the  MouseKeys  control  is  enabled,  a  server  action  of   type
       XkbSA_MovePtr   instructs   the   server   to   generate  core  pointer
       MotionNotify events rather than  the  usual  KeyPress  event,  and  the
       corresponding KeyRelease event disables any mouse keys timers that were
       created as a result of handling the XkbSA_MovePtr action.

       The type field of the XkbPtrAction structure is always XkbSA_MovePtr.

       The flags field is a bitwise inclusive OR of the masks shown  in  Table
       1.

       XkbSA_NoAcceleration   If   not  set,  and  the  MouseKeysAccel
                              control   is   enabled,   the   KeyPress
                              initiates  a  mouse  keys timer for this
                              key; every time the timer  expires,  the
                              cursor moves.
       XkbSA_MoveAbsoluteX    If  set,  the X portion of the structure
                              specifies the new pointer X  coordinate.
                              Otherwise, the X portion is added to the
                              current   pointer   X   coordinate    to
                              determine the new pointer X coordinate.
       XkbSA_MoveAbsoluteY    If  set,  the Y portion of the structure
                              specifies the new pointer Y  coordinate.
                              Otherwise, the Y portion is added to the
                              current   pointer   Y   coordinate    to
                              determine the new pointer Y coordinate.

       Each  of  the  X  and  Y  coordinates  of the XkbPtrAction structure is
       composed of two signed 16-bit values, that  is,  the  X  coordinate  is
       composed  of  high_XXX and low_XXX, and similarly for the Y coordinate.
       Xkb provides the following macros, to convert between a signed  integer
       and two signed 16-bit values in XkbPtrAction structures.
