XkbPtrActionY(3)          XKB FUNCTIONS          XkbPtrActionY(3)



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

SYNOPSIS
       int XkbPtrActionY macro ( act )
             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 han-
       dling 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  con-
                              trol  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 deter-
                              mine 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 deter-
                              mine the new pointer Y coordinate.

       Each of the X  and  Y  coordinantes  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 fol-
       lowing macros, to convert between a signed integer and two
       signed 16-bit values in XkbPtrAction structures.
