In a simple 2D plotter built with visad, I'd like to detect which line (or lines) the mouse is over. I have registered a DisplayListener on the Display, but I am uncertain how to do two things: - detect mouse motion events (now I just get MOUSE_PRESSED and RELEASEd) - figure out which line the mouse is over - display a small tooltip-like tranisent window on top of the display, announcing the name of the line. Tips on any of these points will be most welcome! - Paul
