问题：

场景构建器不能加载自定义组件(Ikonli)，我错过了什么？

南宫凡
2023-03-14

我开始在JavaFX应用程序中使用Ikonli。我将它添加到我的依赖项中：

compile "org.kordamp.ikonli:ikonli-javafx:1.9.0"
compile "org.kordamp.ikonli:ikonli-fontawesome-pack:1.9.0"

然后我将它添加到我的FXML中：

<?import org.kordamp.ikonli.javafx.FontIcon?>

但添加后，场景构建器就不能再加载文件了。我得到这个错误：

我错过了什么？我该怎么做才能让这件事成功？

这就是我为解决这个问题所做的。从https://mvnrepository.com/artifact/org.kordamp.ikonli下载ikonli-core、ikonli-javafx和ikonli-fontawesome-pack jar文件。确保将所有这三个库导入到Scene Builder（确保您正在使用来自Gluon的Scene）中，就像Jose Pereda在上面的帖子中提到的那样。

如果您正在使用IntelliJ idea，请转到File->Project structure。选择“平台设置”->“全局库”。点击“+”图标并将下载的所有3个库导入到项目中。

最后，创建一个module-info.java文件，并为FontIcon类添加所需的导入，您就可以开始了！您的module-info类应该如下所示：

module yourProjectName{
    requires javafx.fxml;
    requires javafx.graphics;
    requires javafx.controls;
    requires org.kordamp.iconli.core;
    requires org.kordamp.ikonli.javafx;
    requires org.kordamp.ikonli.fontawesome;
    opens sample;
}
 类似资料：
  • 在intelliJ中为FXML场景构建器添加自定义组件

  • 同一项目和场景构建器中的JavaFX自定义组件
