How to set CSS file to whole application JafaFX

Question

I want to set one css file to my whole application. I read several similar topic, but I didn't find solution. This is my code:

@Override
public void start(Stage primaryStage) throws Exception{
    Parent root = FXMLLoader.load(getClass().getResource("../view/MainView.fxml"));
    Scene scene = new Scene(root); 
    scene.getStylesheets().add(this.getClass().getResource("modena_dark.css").toExternalForm());

    primaryStage.setScene(scene);
    primaryStage.show();
}

There is no error, just stylesheet doesn't work and app window looks standard. File "modena_dark.css" is in the same directory as file with this code.

If your .css file is in the same directory as your java class, try using:

scene.getStylesheets().add("/yourpackage/modena_dark.css");

This works for me without any problems.
