Get the View in the Controller

I want to ask how I can get the view I am showing in my controller. The reason I want to do this is that a DirectoryChooser Dialog requires an ownerWindow in order to work correctly.

Is there any other solution?

    DirectoryChooser directoryChooser = new DirectoryChooser();
    File file = directoryChooser.showDialog(/*I need a javafx.stage.window here!*/);

Just fetch the current window's reference from any scene graph element that is currently being shown.

element.getScene().getWindow()

For example, if the dialog opens up from the action of a button, you can fetch the window from the button reference. The code would look like :

button.setOnAction(e -> {
    DirectoryChooser directoryChooser = new DirectoryChooser();
    File file = directoryChooser.showDialog(button.getScene().getWindow());
});

Not suggesting this is the right way of doing this but this is cretainly a way. The arguments against using public static should be born in mind here.

public class App extends Application {

  public static App mainApp;
  public static Stage mainStage;

  @Override
  public void start(Stage stage) throws Exception {
    // Remember me.
    mainApp = this;
    mainStage = stage;

You can then use:

    File newLocation = chooser.showDialog(App.mainStage);
