  +--ncsa.devices.mouse.MouseDevice

public class MouseDevice

extends java.lang.Object

implements PortfolioEventReceiver, ncsa.devices.Fake2DInputDevice

This object samples MouseEvents and translates them into a series buttons presses (3types) and vector representation of the mouse(x&y only) This is considered an intermediate step to building a Java3D InputDevice as it seems appropriate to lump all types of 2d input devices together. This gives us the added benefit of writing Generic drivers that take a well defined 2d input (with buttons) and morph it into a 3d transform (complete with rotations and translations). The output consists of the following : an array of button values (3), which are ints. a vector, whose current value is the last mouse screen coordinate location when any button was down.
