JavaFX-为整个应用程序设置默认的CSS样式表

Question

I'm pretty new to JavaFX, I'm trying to change my application aspect via CSS. First time it works fine, when I switch to another scene CSS' classes are not applied. Because my project has 10 scenes, I prefer to use a single CSS file to apply my style to all scenes by using this statement: StyleManager.getInstance().addUserAgentStylesheet(this.getClass().getResource("/style.css").toExternalForm()); into start() method. How can I apply to all scenes my CSS file globally?

Answer 1

You can do it with the following two lines:

Application.setUserAgentStylesheet(Application.STYLESHEET_MODENA);
StyleManager.getInstance().addUserAgentStylesheet(getClass().getResource("/style.css").toString());

The first line will set the default stylesheet to modena (here you could even choose to set JavaFX2 caspian as default stylesheet) using Application#setUserAgentStylesheet , while the second line will add your stylesheet to the user agent stylesheet list.

It's not the nicest solution as StlyeManager is a private API (and will remain in JDK9 as it is now).

Other solution would be to subclass Scene , in which subclass you can add your stylesheet by default, then rather than instantiating Scene , you could create instances of your subclass.
