Class Spacer

  • public class Spacer
extends Control
    Control used to add a space between controls. It shows nothing on screen. Here's a sample of how to use it: 
     Spacer s;
 add(s = new Spacer("  "),CENTER,AFTER+2);
 add(btnClear = new Button("Clear"), AFTER,SAME, s);
 add(btnOK = new Button("OK"), BEFORE, SAME, SAME, SAME, s);
    This sample will place two buttons centered on screen, like this:
