You can do this with a lookup: you have to assume the thumb is a Pane
(or a subclass thereof):
import javafx.application.Application;
import javafx.geometry.Insets;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.control.Slider;
import javafx.scene.layout.Pane;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
public class SliderWithLabeledThumb extends Application {
@Override
public void start(Stage primaryStage) {
Slider slider = new Slider();
StackPane root = new StackPane(slider);
root.setPadding(new Insets(20));
Scene scene = new Scene(root);
slider.applyCss();
slider.layout();
Pane thumb = (Pane) slider.lookup(".thumb");
Label label = new Label();
label.textProperty().bind(slider.valueProperty().asString("%.1f"));
thumb.getChildren().add(label);
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
