I am using the following code to change the cursor within a applet (source given by anguslai):

Object theFrame=null;
         
    theFrame=getParent();

     while(!(theFrame instanceof Frame) && theFrame!=null) {
           theFrame=((Component)theFrame).getParent();
     }

    if (theFrame!=null) {
               ((Frame)theFrame).setCursor(Frame.HAND_CURSOR);

          But the mouse cursor changed to Window´s "alternate select" cursor. Anyone know how to change the cursor to the "little hand"?

Cursor in JDK 1.1 is an object in itself. You will have to create an instance of the cursor and then call it. Following is a sample program , it has a Frame and a button on that Frame. If you point the cursor to the button the cursor will become a Hand cursor.

// Save the program in CursorTest.java and compile and run
import java.awt.*;

public class CursorTest extends Frame {

public static void main(String args[]){

Cursor HandCursor = new Cursor(Cursor.HAND_CURSOR);

CursorTest f1 = new CursorTest();
f1.setLayout(new FlowLayout());
f1.setSize(300,200);

Button bt = new Button("Change cursor to HAND when

pointed here");

f1.add(bt);

bt.setCursor(HandCursor);

f1.setVisible(true);

}
}

Is there no way using JDK 1.0?

In 1.0 you can have a Hand Cursor as follows. I have tested it in 1.1 but this should work fine in 1.0 .

// Save this program in a file CursorTest10.java
import java.awt.*;

public class CursorTest10 extends Frame {

public static void main(String args[]){


CursorTest10 f1 = new CursorTest10();
f1.setLayout(new FlowLayout());
f1.setSize(300,200);

Button bt = new Button("Change cursor to HAND");

f1.add(bt);

f1.setCursor(Frame.HAND_CURSOR);

f1.show();

}
}

The problem is, I am trying change the cursor in "Applet", not a independent program.

I am afraid NO ! That is a limitation of JDK 1.0 why not move to 1.1 ? If you want to stick with 1.0 you may be forced to bring up a frame. Try instantiating a Frame but don't do a show()and try using it to set the Cursor on the Applet. There are chances that it may work.
