[JAVA2D] Elastic band

[Gary Roussak]

Can anyone point me at any examples that tell me how to program the stretching of a rectangular 'elastic band' over some form of drawing canvas, using a click & drag action of the mouse ? Hopefully you know what I mean - I'm trying to simulate in Java 2D the metaphor used by many of the typical drawing programs for selecting a rectangular area of the screen.   Many thanks.
