title: LIBGDX : add a clickable text link
body: <p>I'm developing a little game with libgdx and in my about screen I would like to have a label (wrapped in a table) in which there would have a clickable text link (underlined or with a different color) like this:</p>
  
  <p>You can review the code here</p>

  <p>Edit:</p>
  
  <p>What I've tried is:</p>
  
  <pre><code>HorizontalGroup monGroup = new HorizontalGroup();
  Label howRotationRep = new Label("They have been based on the information provided on this ", new Label.LabelStyle(game.petiteFont, Color.WHITE));
  howRotationRep.setWrap(true);
  howRotationRep.setWidth(tailleCell);
  
  Label test = new Label(" site", new Label.LabelStyle(game.petiteFont, Color.RED));
  test.addListener(new ClickListener(){
  @Override
  public void clicked(InputEvent event, float x, float y) {
  
     Gdx.net.openURI("http://tetrisconcept.net/wiki/SRS");
  
  }
  });
  monGroup.addActor(howRotationRep);
  monGroup.addActor(test);
  table.add(monGroup).left().width(tailleCell);
  </code></pre>
  
  <p>And it gives me this</p>
