DRAW-POINTER(2)                                   DRAW-POINTER(2)

     NAME
          Pointer - state of a pointer device such as a mouse

     SYNOPSIS
          include   "draw.m";
          draw := load Draw Draw->PATH;

          Pointer: adt
          {
              buttons:  int;
              xy:       Point;
          };

     DESCRIPTION
          buttons   Each button on the device corresponds to a bit in
                    buttons; zero bits indicate released (or non-
                    existent), and one bits indicate pressed.  The
                    bits, from least to most significant positions,
                    represent the buttons from left to right.

          xy        The pointer's screen coordinates.

          Mux(1) uses the cptr member of the Draw->Context adt to pass
          pointer events through to applications.
