How do I open the JavaFX FileChooser from a controller class?

Question

My problem is that all the examples of using FileChooser requires you to pass in a stage. Only problem is that my UI is defined in an fxml file, which uses a controller class separate from the main stage.

@FXML protected void locateFile(ActionEvent event) {     FileChooser chooser = new FileChooser();     chooser.setTitle("Open File");     chooser.showOpenDialog(???); } 

What do I put at the ??? to make it work? Like I said, I don't have any references to any stages in the controller class, so what do I do?

Answer 1

For any node in your scene (for example, the root node; but any node you have injected with @FXML will do), do

chooser.showOpenDialog(node.getScene().getWindow());
