title: What is a "Node" in JavaFx/FXML?
body: <p>What is meant by the word &quot;Node&quot; within context of JavaFx/FXML? If I search for this question, all I find are people using the term discussing something else, but no explanation. For example, this answer to the question:  <a href="https://stackoverflow.com/questions/25491732/how-do-i-open-the-javafx-filechooser-from-a-controller-class">How do I open the JavaFX FileChooser from a controller class?</a>:</p>
  <blockquote>
  <p>For any node in your scene (for example, the root node; but any node
  you have injected with @FXML will do), do</p>
  <p><code>chooser.showOpenDialog(node.getScene().getWindow());</code></p>
  </blockquote>
  <p>What would the node be, and how for that matter would I &quot;inject it with @FXML&quot;?</p>
