Answer 1

i need to override the keychar method in pop-up screen,search for escape and then close

code :

 popupscreen1=new PopupScreen(myverticalfieldmanager)
            {
                protected boolean keyChar(char c, int status, int time) 
                {
                    if (c == Characters.ESCAPE)   
                       close();
                    return super.keyChar(c, status, time);
                }

            };
