I would like to programmatically set a border around a Form component in Java. How can I do this without having to edit the css style sheet?

推荐答案

您可以使用已经定义边框的 Panel 组件包装表单.否则，除了使用 CSS 之外，别无选择.

You could wrap the form with a Panel component, which has a border defined already. Otherwise, not much alternatives than just using CSS.

如果您希望留在服务器环境中，一种选择是使用 CSSInject 附加组件并使用它添加边框(您仍然需要编写 CSS，但您可以在服务器上的 Java 文件中执行此操作)而不是在常规 CSS 文件中).

One option, if you wish to stay inside the server environment, is to use the CSSInject add-on and add the border using that (you still need to write CSS, but you can do it on the server in a Java file and not inside a regular CSS file).
