JavaFX滑块:如何仅按增量拖动拇指

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Slider;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;

public class SliderExample extends Application {

    @Override
    public void start(Stage primaryStage) {
        Slider slider = new Slider();
        slider.setMin(0);
        slider.setMax(100);
        slider.setBlockIncrement(10); // 设置大步增量值
        slider.setUnitIncrement(1); // 设置小步增量值

        VBox root = new VBox(slider);
        Scene scene = new Scene(root, 200, 100);
        primaryStage.setScene(scene);
        primaryStage.show();
    }

    public static void main(String[] args) {
        launch(args);
    }
}
