Whats a good way of resizing a String so it fits the Scene?

[Bernard Rosseel]

I have a txt-file which contains a very long String,which is put into a Label. This label's width exceeds the width property of the Scene and Stage on which it is mounted however.
So a scrolling bar appears at the bottom of the Stage so I can see the end of the String.
This is quite unhandy ofcourse and it would be better if all the text is automatically constrained to the size of the Scene/Stage.

Ive looked intothe official documentation but without much succes.

public Card(CardContent c){
        FlowPane fp =new FlowPane();
        Label question = new Label(c.getQuestion());
        // c.getAnswer() will result in an extremely long line
        final Label answer = new Label(c.getAnswer());
        Button showAnswer = new Button("answer");
        showAnswer.setAlignment(Pos.CENTER);
        showAnswer.setOnAction(new EventHandler<ActionEvent>(){

            @Override
            public void handle(ActionEvent t) {
                StackPane sp = new StackPane();
                sp.getChildren().add(answer);
                Scene sc2 = new Scene (sp,400,400);
                Stage st = new Stage();
                st.setScene(sc2);
                st.show();
            }
            
        });
        fp.getChildren().addAll(question,showAnswer);
        Scene sc = new Scene(fp,300,300);
        setScene(sc);
        show();
    }
}

I found a partly solution.
nodeObject.setWrapText(true);

This made it wrap stuff up but just not enough. It still is bigger than the Stage.
