Changing the image of the mouse

Hi! I saw some scenarios, where the mouse had no Image... How can I change the Image of the mouse?

First you have to Import these clases:

import greenfoot.core.WorldHandler;
import javax.swing.*;
import java.awt.Cursor;
import java.awt.Point;
import java.awt.Toolkit;

and then use this Method:

     public void ChangeMouseImage(GreenfootImage image, int XClick, int YClick)
    {
        JPanel Panel = WorldHandler.getInstance().getWorldCanvas();
        Cursor Cursor;
        Toolkit Tk = Toolkit.getDefaultToolkit();
        Point CursorPoint= new Point(XClick,YClick);
        Cursor = Tk.createCustomCursor(image.getAwtImage(),CursorPoint,"Somehow");
        Panel.setCursor(Cursor);
    }

It would be better if you call the Method every round... Else there might be some Problems... XClick and YClick is the Location on your Image, where the mouse has to click... The Point (0,0) is the Point (1,1) on the Image. XClick and YClick has to be Positive! The mouse Image has to be 32x32. If not, it will be scaled automatic... If you want to have no Image for the mouse, you just write:

ChangeMouseImage(new GreenfootImage(1,1),0,0);

Where abouts in this code do you define the 32 x 32 image to use?

You can define the image wherever you want. That it is scaled to 32x32 is not programmed by me. That's done by the given Toolkit-class from Java.
