How to close a JavaFX application on window close

Question

In Swing you can simply use setDefaultCloseOperation   to shut down the entire application when the window is closed   However in JavaFX I can t find an equivalent  I have multiple windows open and I want to close the entire application if a window is closed  What is the way to do that in JavaFX   Edit   I understand that I can override setOnCloseRequest   to perform some operation on window close  The question is what operation should be performed to terminate the entire application   stage setOnCloseRequest new EventHandler lt WindowEvent gt           Override     public void handle WindowEvent event            stop                The stop   method defined in Application class does nothing

This seemed to work for me   EventHandler lt ActionEvent gt  quitHandler   quitEvent - gt             System exit 0                  Set the handler on the Start Resume button     quit setOnAction quitHandler

Instead of playing around with onCloseRequest handlers or window events  I prefer calling Platform setImplicitExit true  the beginning of the application   According to JavaDocs        If this attribute is true  the JavaFX runtime will implicitly   shutdown when the last window is closed  the JavaFX launcher will call   the Application stop   method and terminate the JavaFX   application thread     Example    Override void start Stage primaryStage        Platform setImplicitExit true                 create stage and scene

For me only following is working   primaryStage setOnCloseRequest new EventHandler lt WindowEvent gt           Override     public void handle WindowEvent event             Platform exit             Thread start   new Thread new Runnable                  Override             public void run                       TODO Auto-generated method stub                 system exit 0                                           start start

Try   System exit 0     this should terminate thread main and end the main program

The application automatically stops when the last Stage is closed  At this moment  the stop   method of your Application class is called  so you don t need an equivalent to setDefaultCloseOperation    If you want to stop the application before that  you can call Platform exit    for example in your onCloseRequest call   You can have all these information on the javadoc page of Application   http   docs oracle com javafx 2 api javafx application Application html

Some of the provided answers did not work for me  javaw exe still running after closing the window  or  eclipse showed an exception after the application was closed   On the other hand  this works perfectly   primaryStage setOnCloseRequest new EventHandler lt WindowEvent gt           Override     public void handle WindowEvent t            Platform exit            System exit 0

For reference  here is a minimal implementation using Java 8     Override public void start Stage mainStage  throws Exception        Scene scene   new Scene new Region         mainStage setWidth 640       mainStage setHeight 480       mainStage setScene scene          this makes all stages close and the app exit when the main stage is closed     mainStage setOnCloseRequest e - gt  Platform exit            add real stuff to the scene          open secondary stages    etc

You MUST override the  stop    method in your Application instance to make it works  If you have overridden even empty  stop    then the application shuts down gracefully after the last stage is closed  actually the last stage must be the primary stage to make it works completely as in supposed to be   No any additional Platform exit or setOnCloseRequest calls are need in such case
