How to show make a hidden form visible in javafx


I have an application that is designed to be a sandwich shop system and I have a main menu form that is my main class i.e. this class holds my main class and is the first form to open when the application is executed.

<a href="https://i.stack.imgur.com/IW9e5.png" rel="nofollow"><img alt="enter image description here" class="b-lazy" data-src="https://i.stack.imgur.com/IW9e5.png" data-original="https://i.stack.imgur.com/IW9e5.png" src="https://etrip.eimg.top/images/2019/05/07/timg.gif" /></a>

When I click on the create new standard order button I have it so it will display a menu of items to chose from. I have this code behind the create new standard order button so it will hide the first window and display the next window.

btnStdOrder.setOnAction(e -> { ((Node)e.getSource()).getScene().getWindow().hide(); NewOrderPopUp.Display(); });

However, how do I go back to this first window? I have tried using the same code as above but because the first form holds my main and start methods I cant recall them again using the above method (or maybe I can I just don't know how to do it). Any help would be greatly appreciated.


If your popUpDisplay method ends with showAndWait(), you can try this:

((Stage)((Node)e.getSource()).getScene().getWindow()).hide(); NewOrderPopUp.Display(); ((Stage)((Node)e.getSource()).getScene().getWindow()).show();

I created a sample app that shows this behavior in action.
