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.
