NAME

       XkbPtrActionY - Returns the high_YYY and low_YYY fields of act converted to a signed int

SYNOPSIS

       int XkbPtrActionY (XkbPtrAction act);

ARGUMENTS

       - act  action from which to extract Y

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.
