It is used in a application where the input device is a usb keypad with numbers and # key. I am trying  to use the # key as deliminator to obtains the numerics from the text box. Everything works  except the # (Delimiter) key gets placed in the textbox after processing and I do not know how to remove it to prepare for next input.  It needs to be removed because there is no backspace key. Code snippet follows:         gameInput.addKeyPressHandler(new KeyPressHandler() {             @Override             public void onKeyPress(KeyPressEvent event) {                 int keycode = event.getCharCode();                 if (keycode == '#') {                     String gamecode = gameInput.getText();                                         gameInput.clear();                     gameInput.setText(""); .....
