code: @Override
  	public void handleRequest(final Request request) {
  		if (plainBtn.isPressed()) {
  			WMessages.getInstance(this).info("Plain button pressed.");
  		}
  
  		if (linkBtn.isPressed()) {
  			WMessages.getInstance(this).info("Link button pressed.");
  		}
  	}
docs: Override handleRequest in order to perform processing specific to this example. Normally, you would attach
  actions to a button rather than calling "isPressed" on each button.
  
  @param request the request being responded to.
