Javafx close stage. What makes you think it will close all stages? Also, the way to "kill/close" a stage in JavaFX is to hide it. In Controller1 it creates a new stage that opens on top of the main one. In JavaFX, you can listen for the close event of a stage (window) by adding an setOnCloseRequest event handler to the Stage object. close, which is equivalent to Stage. hide, only closes the one Stage (and its descendants, if any). println("Stage is cl However in JavaFX I can't find an equivalent.

You create a JavaFX Stage object just like any other Java object: Using the new command and the Stage constructor. close() or stage. This action places this Stage at the bottom of the stacking order and shows it behind any other Stage created by this application. java in method that handles the action event on the closing button. Closing an FXML window in JavaFX involves referencing the window's Stage instance from within the Controller. setOnCloseRequest(event -> { System. This event handler allows you to perform actions when the user attempts to close the stage, such as confirming the close operation or performing cleanup tasks. Text; import javafx. scene. Stage; Stage { title: "Welcome to JavaFX!" scene: Scene { content: Text { x: 25 y: 25 content: "Hello World!" font: Font{ size: 32 } } } } produces the following on Mac OSX: produces the Is there any way to get it to close when I kill the main stage without writing code to track every single new window created?

The only way I found myself to be able to do this, was to define a public static Stage aboutBox; inside the Builder. java class and reference to that one from within the AboutBox. Many of the Stage properties are read only because they can be changed externally by the underlying platform and therefore must not be bindable. Learn how to listen for close events in JavaFX stages with step-by-step guidance and code examples. This is exactly what the OP asked, isn't it??? I'd like to know if there is a simple solution that tells the dialogstage to close when the primary stage does and where I don't have to write much code outside of my try/catch. Scene; import javafx.

In JavaFX, understanding the life cycle of an application is crucial for managing its behavior effectively. Instead of creating a new Stage as you have done in your initial attempt, you should retrieve the existing Stage related to the current scene. The process involves constructing an instance of the specified Application class, calling the init() method, starting the application with The JavaFX Stage class is the top level container for the FX script instantiation. hide() do this in fx how to implement this in fxml?
