Method

booleanisScrolledToBottom(final JScrollPane scrollPane)
Checks whether the given JScrollPane is currently scrolled to the bottom of its view. 
final BoundedRangeModel m = scrollPane.getVerticalScrollBar().getModel();
return m.getValue() + m.getExtent() >= m.getMaximum();
voidmakeComponentDragScrollable(final JComponent component)
Makes a component drag-scrollable. 
final MouseAdapter dragHandler = new MouseAdapter() {
    int dragStartX, dragStartY;
    @Override
    public void mousePressed(final MouseEvent event) {
        if ((event.getModifiers() & InputEvent.BUTTON1_MASK) != 0) {
            dragStartX = event.getXOnScreen();
            dragStartY = event.getYOnScreen();
    };
    @Override
    public void mouseDragged(final MouseEvent event) {
        if ((event.getModifiers() & InputEvent.BUTTON1_MASK) != 0) {
            final Rectangle visibleRect = component.getVisibleRect();
            visibleRect.x += (dragStartX - event.getXOnScreen()) * 2;
            visibleRect.y += (dragStartY - event.getYOnScreen()) * 2;
            component.scrollRectToVisible(visibleRect);
            dragStartX = event.getXOnScreen();
            dragStartY = event.getYOnScreen();
};
component.addMouseListener(dragHandler);
component.addMouseMotionListener(dragHandler);
component.setCursor(Cursor.getPredefinedCursor(Cursor.MOVE_CURSOR));
