StyleManager#reloadStylesheets(Scene) replacement in FX8

[Tom Schindl]

Hi David,

Interesting I think my problem is very special because when ever I
reload my FXML-Preview I'm constructing a completely new scene and
simply set a new scene on the Stage (well in my case it is an FXCanvas
but that's not the real problem).

I reduced the problem to the following:

> public class MyCSSReloadTest extends Application {
> 
>     public static void main(String[] args) {
>         MyCSSReloadTest.launch(args);
>     }
>     
>     private Scene createScene(final Stage primaryStage) {
>         BorderPane p = new BorderPane();
>         final Scene s = new Scene(p,400,400);
>         final String stylesheet = MyCSSReloadTest.class.getResource("my.css").toExternalForm();
>         s.getStylesheets().add(stylesheet);
>         Button b = new Button("Reload "+  System.currentTimeMillis());
>         b.setOnAction(new EventHandler<ActionEvent>() {
> 
>             @Override
>             public void handle(ActionEvent event) {
>                 // s.getStylesheets().clear();
>                 primaryStage.setScene(createScene(primaryStage));
>             }
>         });
>         p.setCenter(b);
>         return s;
>     }
> 
>     @Override
>     public void start(Stage primaryStage) throws Exception {
>         primaryStage.setScene(createScene(primaryStage));
>         primaryStage.show();
>     }
> 
> }


if you uncomment thje s.getStylesheets().clear() the reloading works as
expected. I'm not sure now if this is expected behavior for performance
optimization you are not parsing the CSS when it is already on another
although soon to be GC'ed scene.
