Automatic scrolling using textareas.

Question

My application has a jscrollpane with several components being dynamically created. It adds jtextareas just fine, however, when it populates the jtextareas with text, it scrolls down to the last text area. My users do not want this. How can I get around the auto-scrolling when the jtextareas use the setText( ) method?

I did some fiddling with this about a year ago. I don't remember the details, but according to some leftover code something like this might do the trick:
    Document d = textarea.getDocument();
    try {
        d.insertString(d.getLength(), s, null);
    } catch (BadLocationException ble) {
        //Shouldn't happen when getLenght() is used for index.
        //If it happens anyway, write a stacktrace and
        //otherwise ignore it.
        ble.printStackTrace();
    }If this does not work, you should something like this: (very rough and untested. Read the API for details.)
    int currentPosition = scrollpane.getVerticalScrollbar().getPosition();
    // ... do the adding ...
    scrollpane.getVerticalScrollbar().setPosition(currentPosition);
