now thanks to that info you could overwrite the typed value?
or ( as i not fully understand your use case )
i try to empty it and give the user a new prompt text

public void handleTextEvents(GEditableTextControl textcontrol, GEvent event) {
  if ( textcontrol == txf1  && event == GEvent.ENTERED) {
    t0 = txf1.getText();
    println("ENTER: "+t0);
    txf1.setFocus(false);  //  @quark is the best
    //txf1.setText("over write new?");
    txf1.setText("");
    txf1.setPromptText("next value");
  }
}

even something like

public void handleTextEvents(GEditableTextControl textcontrol, GEvent event) {
  if ( textcontrol == txf1  && event == GEvent.ENTERED) {
    t[count] = txf1.getText();
    count++;
    txf1.setFocus(false); 
    txf1.setText("");
    txf1.setPromptText("next value t["+count+"]");
  }
}
