我有一个基于 TitledToolBar 的自定义布局管理器，无论如何它在 fxml 文件之外运行良好，但是当我尝试将它包含在 Scene Builder 11 以提高生产力时：

自定义布局：

package MyStage;

import java.io.IOException;
import javafx.fxml.FXMLLoader;

public class CustomLayout extends TitledToolBar{
    
    public CustomLayout(){
         FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource(
"/Test.fxml"));
        fxmlLoader.setRoot(this);
        fxmlLoader.setController(this);

        try {
            fxmlLoader.load();
        } catch (IOException exception) {
            throw new RuntimeException(exception);
        }
    }
}

Test.fxml：

    <?xml version="1.0" encoding="UTF-8"?>
    
    <?import javafx.scene.layout.AnchorPane?>
    <?import MyStage.CustomLayout?>
    
    
    <fx:root type="MyStage.CustomLayout" xmlns:fx="http://javafx.com/fxml" >
    
    </fx:root>

为什么找不到班级位置？我不知道该怎么办了...我想我遵循了有关如何从 Oracle's website 创建自定义组件的所有说明。这些天看起来没有人再关心 JavaFX 了...请帮忙！如果这样，我会按照 Ensemble 自定义标题栏源作为示例： Ensemble8，是真的。
