How to set a slider change listener to fire only when mouse drag is released in JavaFX?

Question

I have a working code in JavaFX for sliders, but it fires everytime there is any change in the slider and I want it to only fire a change when the mouse drag event is released.

Below is the code:

sliderMarkerSize.valueProperty().addListener(new ChangeListener<Number>() {
        public void changed(ObservableValue<? extends Number> ov,
            Number old_val, Number new_val) {
                markerSize = new_val.intValue();
                communalWeb();
            }

    });

How to make it only change my graph when mouse is released?

Answer 1

Use OnMouseReleased.

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

/**

 * @author blj0011
 */
public class JavaFXApplication231 extends Application
{

    @Override
    public void start(Stage primaryStage)
    {


        Slider slider = new Slider(0, 100, 0);
        slider.setOnMouseReleased(event -> {
            System.out.println(slider.getValue());
        });
        StackPane root = new StackPane(slider);

        Scene scene = new Scene(root, 300, 250);

        primaryStage.setTitle("Hello World!");
        primaryStage.setScene(scene);
        primaryStage.show();
    }

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args)
    {
        launch(args);
    }

}
