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 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  con-trol control
                              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 determine

       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 determine

       Each of the X and Y coordinantes of the XkbPtrAction structure is composed of two signed 16-bit  val-ues, values,

       values in XkbPtrAction structures.
