  txa1.tag = "txa1";
  txa1.setPromptText("Text area 1");

}

public void draw() {
  background(200, 128, 200);

  String extra = " event fired at " + millis() / 1000.0 + "s";
  print(name + "   ");

    println("CHANGED " + extra);

    println("ENTERED " + extra);  
    break;
  default:
    println("UNKNOWN " + extra);
  }
}

public void handleTextEvents(GEditableTextControl textControl, GEvent event) { 
  displayEvent(textControl.tag, event);
}

-d- @quark
why i can not have a empty line by [enter]

-e- so, now i want understand your question?
what you want to do?
save the content of the edited text area to a file?
( basic feature of a text editor )

or add some more text from any string into the text area
++ at the end?
++ at cursor position? ( that one might be tricky )
