Hi

    I implemented mouse listener in this classes below but when I put
my mouse over this button, it doesn't work. Help!

public class MouseListenerImpl implements MouseListener
{

    /**
     * The onFocusImage.
     */
    private Image onFocusImage;

    /**
     * The lostFocusImage.
     */
    private Image lostFocusImage;

    public MouseListenerImpl(Image onFocusImage, Image lostFocusImage)
    {
        this.onFocusImage = onFocusImage;
        this.lostFocusImage = lostFocusImage;

    }

    /* (non-Javadoc)
     * @see
com.google.gwt.user.client.ui.MouseListener#onMouseDown(com.google.gwt.user.client.ui.Widget,
int, int)
     */
    public void onMouseDown(Widget sender, int x, int y)
    {
        // TODO Auto-generated method stub

    }

    /* (non-Javadoc)
     * @see
com.google.gwt.user.client.ui.MouseListener#onMouseEnter(com.google.gwt.user.client.ui.Widget)
     */
    public void onMouseEnter(Widget sender)
    {
        sender = onFocusImage;

    }

    /* (non-Javadoc)
     * @see
com.google.gwt.user.client.ui.MouseListener#onMouseLeave(com.google.gwt.user.client.ui.Widget)
     */
    public void onMouseLeave(Widget sender)
    {
        sender = lostFocusImage;

    }

    /* (non-Javadoc)
     * @see
com.google.gwt.user.client.ui.MouseListener#onMouseMove(com.google.gwt.user.client.ui.Widget,
int, int)
     */
    public void onMouseMove(Widget sender, int x, int y)
    {
        // TODO Auto-generated method stub

    }

    /* (non-Javadoc)
     * @see
com.google.gwt.user.client.ui.MouseListener#onMouseUp(com.google.gwt.user.client.ui.Widget,
int, int)
     */
    public void onMouseUp(Widget sender, int x, int y)
    {
        // TODO Auto-generated method stub

    }

    /**
     * @param args
     */
    public static void main(String[] args)
    {
        // TODO Auto-generated method stub

    }

}

then i call it here

    Image onFocusTop = new Image("latoureiffel8.jpg");
    Image lostFocusTop = new Image("Illuminaughti.jpg");

    MouseListenerImpl mouseListenerTopButton = new
MouseListenerImpl(onFocusTop, lostFocusTop);

    lostFocusTop.addMouseListener(mouseListenerTopButton);
    topButtonPanel.add(lostFocusTop);

    RootPanel.get("topButton").add(topButtonPanel);
