我的语法从FXML文件调用样式表（css）有什么问题？ [英] What is wrong with my syntax calling a stylesheet (css) from an FXML file?

问题描述

我在NetBeans 8中使用Java 8 / JavaFX和FXML。

I am working in NetBeans 8, with Java 8 / JavaFX and FXML.

在我的FXML文档的第一个控制器（AnchorPane）中，我有这个，有效：

In the first controller (an AnchorPane) in my FXML document, I have this, that works:

stylesheets="file:///C:/Users/me/Documents/NetBeansProjects/MyApp/src/myApp/myStyle.css"

然而，当我尝试用任何类型的相对路径替换它时，我在运行时收到以下错误：

However, when I attempt to replace that with any type of relative path, I get the following error at runtime:

com.sun.javafx.css.StyleManager loadStylesheetUnPrivileged
WARNING: Resource "myStyle.css" not found.

我试过

stylesheets="myStyle.css"
stylesheets="file://myStyle.css"
stylesheets="./myStyle.css"
stylesheets="css/myStyle.css"

（我把css文件的副本放在一个子目录中）

(where I put a copy of the css file in a subdirectory from where it was)

...可能还有50种其他排列。每次我得到同样的错误。

...and maybe 50 other permutations. Every time I get the same error.

我关心的原因是我遇到了第二个问题。在第一个版本中，它可以在我的机器上运行...当我将我的jar文件带到另一台机器时，运行应用程序时不会应用css ...就像资源文件没有被复制一样。

The reason I care is that I am having a second problem. In the first version, that works on my machine... when I take my jar file to another machine, the css is not applied when the application is run... It's like the resource file isn't copied.

帮助？

谢谢！

推荐答案

让我考虑一下您的项目结构如下

Let me consider your project structure as follows

MyApp
  |
  |_ src
      |
      |_controllers (Controllers)
      |_view (FXML)
      |_style (css)
          |_myStyle.css

您可以使用

<stylesheets>
   <URL value="@../style/myStyle.css" />
</stylesheets>

在你的控制器中，你可以按如下方式添加它

In your controller, you can add it as follows

layout.getStylesheets().add(getClass().
         getResource("/style/myStyle.css")).toExternalForm();
