Removing stylesheets from scene not possible while using CSSFX

[dlemmermann]

While working on dark mode support I noticed that I could not disable the dark mode anymore. I enable dark mode by adding additional stylesheets to my application. Then when I disable the dark mode I do so by removing those added stylesheets. This has no effect when using CSSFX.

Here is an example:

import fr.brouillard.oss.cssfx.CSSFX;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.ToggleButton;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

public class CssFxTest extends Application {

    @Override
    public void start(Stage primaryStage) throws Exception {

        ToggleButton button = new ToggleButton("Switch");
        Scene scene = new Scene(new StackPane(button));

        button.selectedProperty().addListener(it -> {
            if (button.isSelected()) {
                scene.getStylesheets().add(CssFxTest.class.getResource("test-dark.css").toExternalForm());
            } else {
                scene.getStylesheets().remove(CssFxTest.class.getResource("test-dark.css").toExternalForm());
            }
        });

        primaryStage.setScene(scene);
        primaryStage.setTitle("CssFX Test");
        primaryStage.setWidth(400);
        primaryStage.setHeight(400);
        primaryStage.centerOnScreen();
        primaryStage.show();

        CSSFX.start();
    }

    public static void main(String[] args) {
        launch(args);
    }
}

The CSS file just needs this:

.root {
    -fx-base: black;
}
