Example Usage

This example uses the following Cascara classes to display a drop down list of installed themes and apply the chosen one to the scene:

• ThemeEngine
• OptionChooser

Scene scene = new Scene(layout, 800, 500);
ThemeEngine themeEngine = ThemeEngine.instance();

OptionChooser themeChooser = new OptionChooser(
    themeEngine.getThemeOptionProvider(),
    themeEngine.getDefaultThemeOption()
);

themeChooser.getSelectionModel().selectedItemProperty().addListener((obs, old, theme) -> {
    themeEngine.setTheme(theme);
    themeEngine.applyTheme(scene);
});

themeEngine.applyTheme(scene);
