Java SE (Java Platform, Standard Edition)

Hello,

I can't get a Label's width with the following test code.


import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

public class GetLabelWidthTest extends Application {
public static void main(String[] args) {
launch(args);
}

@Override
public void start(Stage primaryStage) throws Exception {
primaryStage.setTitle("Label width test");

StackPane sp = new StackPane();

Label label = new Label();
label.setText("test");

sp.getChildren().add(label);

double width = label.getWidth();
System.out.println(width); // always prints 0

Scene scene = new Scene(sp, 800, 600);
primaryStage.setScene(scene);
primaryStage.show();
}
}


Does anyone know why?

Thanks for your help.
