NAME

       XkbSetPtrActionX  -  Sets  the  high_XXX and low_XXX fields of act from the signed integer
       value x

SYNOPSIS

       void XkbSetPtrActionX (XkbPtrAction act, int x);

ARGUMENTS

       act    action in which to set X

       x      new value to set

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.
