嵌套控制器的 JavaFX8 fxml 命名 [英] JavaFX8 fxml naming of nested controllers

问题描述

给定一个 .fxml 包括:

Given an .fxml include like:

<fx:include fx:id="header" source="Header.fxml" />

Java FXMLdocs 说要创建两个变量，例如:

The Java FXML docs say to create two variables like:

@FXML private HBox header;
@FXML private HeaderController headerController;

控制器变量名由什么决定?是否总是只是包含 ID 后跟控制器"?

What determines the controller variable name? Is it always just the include id followed by "Controller"?

推荐答案

是的，控制器注入的字段名称总是通过连接 <fx 的 fx:id 来构造:include> 带有 "Controller" 的标签.

Yes the field name the controller is injected to is always constructed by concatenating the fx:id of the <fx:include> tag with "Controller".

它隐藏"在 的文档中FXMLLoader.CONTROLLER_SUFFIX 字段.

It's "hidden" in the documentation of the FXMLLoader.CONTROLLER_SUFFIX field.

包含的 fxml 文件的控制器的后缀.完整的键存储在命名空间映射中.

A suffix for controllers of included fxml files. The full key is stored in namespace map.

(命名空间映射包含所有对象，根据它们被注入的字段名称，如果存在这样的字段.)

您可以在此处验证它的值为 "Controller":https://docs.oracle.com/javase/8/javafx/api/constant-values.html#javafx.fxml.FXMLLoader.CONTROLLER_SUFFIX

You can verify that it's value is "Controller" here: https://docs.oracle.com/javase/8/javafx/api/constant-values.html#javafx.fxml.FXMLLoader.CONTROLLER_SUFFIX
