Set Wait Cursor

[Nandini Chakrabarty]

Threre are two Buttons("Save", "Message").If a click "Save" button - it starts to find a particular file from my directory.If file is not there - wait cursor will appear-if file is there wait cursor became default cursor.My main problem is -my wait cursor does not work on window. How can I do it?please give me some solution as early as possible.

My Existing code is as follows -

/*java CursorDemo MyFile.txt*/
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.io.*;
public class CursorDemo extends JFrame
{
JButton jButton1;
JButton jButton2;
FileInputStream  fin;
   boolean b;
    //static CursorDemo cursorInst;
  Container contentpane;
CursorDemo()
{
contentpane = getContentPane();
contentpane.setLayout(new FlowLayout());
    jButton1 = new JButton("Save");
jButton2 = new JButton("Message");
contentpane.add(jButton1);
contentpane.add(jButton2);
        jButton1.addActionListener(new java.awt.event.ActionListener(){
public void actionPerformed(ActionEvent e)
{
       jButton1_actionPerformed(e);
      }
    });

jButton2.addActionListener(new java.awt.event.ActionListener() {
        public void actionPerformed(ActionEvent e)
{
       jButton2_actionPerformed(e);
      }
    });
}
public static void main(String args[])throws IOException
{
 CursorDemo cursorInst = new CursorDemo();
cursorInst.setSize(100,200);
cursorInst.setVisible(true);
   }

  public void jButton1_actionPerformed(ActionEvent e)
{
       //for(;   [img]http://www.javaranch.com/ubb/wink.gif[/img]{
    /* try
          {Thread.sleep(2000);
    }
    catch(InterruptedException ie)
    {
    }
     jButton1.setVisible(false);
    repaint();*/
try
    {
      fin = new FileInputStream("MyFile.txt");
    }
catch(FileNotFoundException er)
{
      System.out.println("File Not Found ");
         jButton2.setEnabled(false);
       //jButton1.getTopLevelAncestor().setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR));
      setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR));
    jButton1.setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR));
   jButton2.setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR));
      return;
  }

      try{}
catch(ArrayIndexOutOfBoundsException er)
{
      System.out.println("Usage : CursorDemo File ");
             return;

}
           System.out.println("File Is There");

       jButton2.setEnabled(true);
   jButton1.setVisible(true);
      setCursor(Cursor.getPredefinedCursor(Cursor.DEFAULT_CURSOR));
    jButton1.setCursor(Cursor.getPredefinedCursor(Cursor.DEFAULT_CURSOR));
   jButton2.setCursor(Cursor.getPredefinedCursor(Cursor.DEFAULT_CURSOR));
    //cursorInst.setCursor(Cursor.getPredefinedCursor(Cursor.DEFAULT_CURSOR));
    //repaint();
    //}
 }
   public void setWaitCursor(boolean b)
    {
     /* if(b==true)
      {
        setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR));
      }
      else
      {
        setCursor(Cursor.getDefaultCursor());
      }*/
    }
 public void jButton2_actionPerformed(ActionEvent e)
 {
      JOptionPane.showMessageDialog(this,"Hi","Hallo",JOptionPane.WARNING_MESSAGE);
   }

Thank you.

ps:
Nandini:
Welcome to the javaranch.
When posting long code (actually any code) please use the [ code ] openinig and closing tags (without the spaces) so that the code is properly formated. Also, I have deleted your other two (exact same) posts -
post once read from anywhere.
Hope you like this place.
Thanks for your cooperation.

Hi Nandini,
I think all you need to do is inside your actionPerformed method is to get the button parent (which should be CursorDemo) and call the setCursor on it.

getParent().setCursor( ... );

Regards,
Manfred.
