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 (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.
