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.
