NAME

       XkbPtrActionX - Returns the high_XXX and low_XXX fields of act converted to a signed int

SYNOPSIS

       int XkbPtrActionX (XkbPtrAction act);

ARGUMENTS

       act    action from which to extract X

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.
