    Determine current Screen

    J. Ishikawa

      I have multiple screens...

      How can I determine on which screen my current application window (stage) is located?
        • 1. Re: Determine current Screen
                  Screen screenX = Screen.getPrimary();
                  ObservableList<javafx.stage.Screen> screens = javafx.stage.Screen.getScreens();
                  for (javafx.stage.Screen screen : screens) {
                      if (screenX.equals(screen)) {
                          System.out.println("primary screen is: " + screen);
                      {System.out.println("Secondary screen is:  " + screen);}

            Thank you for your reply, but your answer doesn't solve my problem to determine, on which screen my JavaFX application is currently located.

            To clarify the problem further...
            When a JavaFX application is loaded, its shown on the primary screen. But when the application window is moved to another screen, how to detect this?

              Hi, you could use the static method [url http://docs.oracle.com/javafx/2/api/javafx/stage/Screen.html#getScreensForRectangle%28double,%20double,%20double,%20double%29]getScreensForRectangle

              Exemple :
              List<Screen> screens = Screens.getScreensForRectangle(stage.getX(),stage.getY(),stage.getWidth(),stage.getHeight());

              As your window can spread accross multiple screens, the result is a list.
