hi,
	i'm having some problems trying to wrap my mind around how the
JDK api handles events. i'm using the JDK and X11R6, if that helps.

I want to be able to make a new TextField that allows me to configure
what happens when keys are pushed. Preferably after I take the
appropriate steps, i'd like to be able to pass a message back to the
parent Applet of the TextField.

however, when i try to override the boolean int keyDown(Event,int)
method, the method never seems to get called.

help/suggestions anyone?

	thanks,
		steve

public class NewTextField extends TextField {
  public MyTextField(String text, int cols) {
    super(text,cols);

  public boolean keyDown(Event evt,int key) {
    System.out.println("keydown!: " + evt.toString() + " key: " + key);
    
    return true;
  };

};

import NewTextField;

public class NewTextFieldTest extends Applet {
    MyTextField userTextInput;

    public NewTextFieldTest() {
      userTextInput = new MyTextField("hello!",80);
      add(userTextInput);
    }

    public void init() {
      resize(500,50);
    };
}
