What I want to do is very simple : when the user enter a letter in the =
JTextField
component, I want to check the letter to put it in upper case if it's =
not!

I have implemented a keyListener and the method keyPressed :

import java.awt.event.*;
import com.sun.java.swing.*;

public class gestionEvent extends KeyAdapter
{   public void keyPressed(KeyEvent evt)
   {  int code=3Devt.getKeyCode();
      char car=3Devt.getKeyChar();


      if (Character.isLowerCase(car))
      { evt.consume();
        char car2=3DCharacter.toUpperCase(car);
        JTextField un_champ=3D(JTextField)evt.getComponent();
        String chaine=3Dun_champ.getText();
        chaine=3Dchaine+car2;
        un_champ.setText(chaine);
      }
   }

The letter is put in upper case and I ask setText to show the new string =
!

THE RESULT is that It shows in the JTextField component the letter in =
UpperCase + in LowerCase !

I have thought that it was the result of the Document associated with my =
JTextField, so I have created my own
document associated with my JTextField and I wrote the methode =
insertUpdate :

import com.sun.java.swing.text.*;

public class un_document extends PlainDocument
{
  public un_document()
   { super();
  }

   public void insertString(int off, String str,AttributeSet a)
   throws BadLocationException
   { char[] source=3Dstr.toCharArray();
     super.insertString(off,str,a);
   }
}

Two times the method insertString is called : with the letter in =
uppercase and lowercase !
How can I catch the second call to insertString with the letter in =
lowercase ?

Can someone help me in anyway ?

Thanks a lot, Anne
