    Hi, I'm writing a graphics program, and I'm currently implementing a
    zoom function. The graphics are drawn on a JPanel wrapped in a
    JScrollPane, and while my zoom is working fine as far as scaling the
    graphics, I'm having a lot of trouble figuring out how to scroll the
    scrollpane. After zooming, I would like to scroll the pane so that the
    point clicked is in the center, so as to follow the "zoom in"
    conventions in other graphics progs. (At the moment, the pane is always
    scrolled top-left after a zoom.) I've tried invoking scrollRectToVisible
    to on the pane's viewport, but it doesn't seem to work. I've also tried
    using the setValue methods on the pane's scrollbars, but that doesn't do
    anything either. Does anyone have any ideas?
