How to hide mouse cursor ?

Question

How can I hide the mouse cursor, when I am over a component ?

Answer 1

I don't know if there is a better way but ...
create a gif (using PaintShop Pro or something) which has nothing in it or if that can't be done as few pixels as possible. I created mine in c:\tmp\blank.gif for the program below
import java.awt.*;
import javax.swing.*;
import java.net.*;
public class ViewCursor
extends JFrame
public ViewCursor()
throws Exception
Cursor myCursor = null;
try
ImageIcon ii = new ImageIcon(new URL("file:C:/tmp/blank.gif"));
Image im = ii.getImage();
Toolkit tk = getToolkit();
myCursor = tk.createCustomCursor(im, new Point(0,0), "MyCursor");
catch (Exception e)
System.out.println("myCursor creation failed " + e);
getContentPane().setLayout(new FlowLayout());
JPanel p1 = new JPanel();
JPanel p2 = new JPanel();
JButton b1 = new JButton("one");
JButton b2 = new JButton("two");
p1.add(b1);
p2.add(b2);
p1.setCursor(myCursor); // set panel 1 to have the customised cursor
getContentPane().add(p1);
getContentPane().add(p2);
public static void main(String[] args)
throws Exception
ViewCursor v = new ViewCursor();
v.setSize(200, 200);
v.setVisible(true);
when you run this, the cursor disappears when its over p1 / b1
