A small example which shows that MouseClick events are listened by both child and its container

Main.java

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

public class Main extends Application {

    @Override
    public void start(Stage primaryStage) throws Exception {

        VBox fxmlContainer  = new VBox();
        fxmlContainer.setStyle("-fx-background-color: ANTIQUEWHITE");
        fxmlContainer.getChildren().add(new Label("Click Anywhere!!"));
        fxmlContainer.setAlignment(Pos.CENTER);

        StackPane stackPane = new StackPane(fxmlContainer);

        fxmlContainer.setOnMouseClicked(event -> System.out.println("You have clicked on VBox"));
        stackPane.setOnMouseClicked(event -> System.out.println("You have clicked on StackPane"));

        Scene scene = new Scene(stackPane, 150, 150);
        primaryStage.setScene(scene);
        primaryStage.show();
    }

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

thanks for the help
