[SOLVED] event handling :backend and front end seperation

[simo_mon]

hi there i have a conceptual question...

i have a gui, which reads keystroke events attached to a textfield

ie

  class Myclass extends JFrame implements ActionListener,KeyListener {

   constructor....

   public void keyPressed(KeyEvent e) 
   {
	System.out.println(" a key has been pressed ");
	System.out.println(" a key code "+e.getKeyCode());
	System.out.println(" a key char  "+e.getKeyChar());
   }

}

no i am trying to keep a seperation between the gui and the backend... so the backend will store and adjust the data ...

ie

    class back{
    
    private int total =;

    constructor...

    get/set total();

my question is can i link the adjustment of the total in the back class, everytime a keystroke is fired in the gui...?

is it that i add a listener to the back class???

the whole idea being here to keep a logical and functional seperation between the gui and the data manipulation part....

thanks

Listeners could work great here. Perhaps you need a 3-part program: View and Model as you have, and also a Control to handle the actions.

wow.... thanks Fubarable ..... that was some code explosion !!!!!!
the listeners were the missing link !!!!!!! Went off and added the keylisteners to the backend, passed a ref to the front and viola !!!!

awesome prompt !!!!!! thanks vry much
