setOn"Fast"Click - JavaFx - javafx

Question

I have a Button that I can move it from the screen, when clicking it has an action. The problem is, when I do Drag'n Drop the click event is called when I release the mouse on, I tried it:
setOnMouseClicked
setOnAction
setOnMousePressed
How can I do to just call the click function when it is a quick click, something like Android times that can differentiate because we have setOnLongClick, so differentiated when I have doing Drag'n Drop and when I really want to click?
Ex:
To move, do:
button.setOnMouseDragged(e -> {
//code move
});
To eventClick:
button.setOnMouseClicked/ Action / MousePressed (e -> {
//call method
});
But when I drop it, it calls setOnMouseClicked / Action / MousePressed, what I want is for it to just call in case I give a quick click, when I drop the drag'n drop do not call.

One option is to keep track of whether or not the Button was dragged; if not, only then execute the code in the onAction handler. Here's an example:
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.geometry.Point2D;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.input.MouseEvent;
import javafx.stage.Stage;
public class Main extends Application {
private Point2D origin;
private boolean wasDragged;
#Override
public void start(Stage primaryStage) {
Button button = new Button("Drag me!");
button.setOnAction(this::onAction);
button.setOnMousePressed(this::onMousePressed);
button.setOnMouseDragged(this::onMouseDragged);
button.setOnMouseReleased(this::onMouseReleased);
primaryStage.setScene(new Scene(new Group(button), 800, 600));
primaryStage.show();
}
private void onAction(ActionEvent event) {
event.consume();
if (!wasDragged) {
System.out.println("onAction");
}
}
private void onMousePressed(MouseEvent event) {
event.consume();
origin = new Point2D(event.getX(), event.getY());
System.out.println("onMousePressed");
}
private void onMouseDragged(MouseEvent event) {
event.consume();
wasDragged = true;
Button source = (Button) event.getSource();
source.setTranslateX(source.getTranslateX() + event.getX() - origin.getX());
source.setTranslateY(source.getTranslateY() + event.getY() - origin.getY());
}
private void onMouseReleased(MouseEvent event) {
event.consume();
origin = null;
wasDragged = false;
System.out.println("onMouseReleased");
System.out.println();
}
}
Unfortunately, I can't find documentation guaranteeing the onAction handler is always called before the onMouseReleased handler, but this worked on both Java 8u202 and JavaFX 11.0.2 when I tried it.
