带有 'CSS' 的 JavaFX：警告：在解析规则“*.text-input”中的“-fx-highlight-fill”查找时无法解析 'accent_color'

Question

为什么会出现此错误？

我的 css 文件来自 https://pixelduke.com/java-javafx-theme-jmetro/ 我不太明白如何将它实现到我的 UI 中，因为它在一个 jar 文件中，我必须创建它--> JMetro(JMetro.Style.LIGHT).applyTheme(root); 但是为了让它工作，我做了什么，我创建了一个单独的 css file/s 并复制并粘贴了它的 css file/s。

Answer 1

@import 在 JavaFX 中不起作用。您需要单独添加所有样式表或使用导入的样式表作为用户代理样式表。后一种方法需要一个完整的样式表，即在标准 api 中设置所有控件的样式，而不引用通常添加到此样式表中的属性之一。

看看 the source code on Github 的预期用途似乎是简单地设置样式并设置 scene 或 parent 属性。您应该能够通过构造函数执行此操作：

JMetro jMetro = new JMetro(root, Style.LIGHT);

除了此库中包含的样式表之外，您还可以添加自己的样式表：

root.getStylesheets().add(myStyleSheet);
