title: Javafx adding ActionListener to button
body: <pre><code>button.setOnAction(new EventHandler&lt;ActionEvent&gt;() {
      @Override public void handle(ActionEvent e) {
          label.setText("Accepted");
      }
  });
  </code></pre>
  
  <p>In the code above we are defining what will happen when we press the button. This is all good but I wanna create new ActionListener and then add it to my button.
  Normally in JButton I can just add ActionListener like this:</p>
  
  <pre><code>button.addActionListener(someControllerClass.createButtonListener());
  </code></pre>
  
  <p>In code above createButtonListener() returns ActionListener.</p>
  
  <p>My question is: What is the equivalent of JButton addActionListener ?</p>
