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

问题描述

给定.fxml包含如下：

Given an .fxml include like:

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

Java FXML docs 说要创建两个变量，如：

The Java FXML docs say to create two variables like:

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

什么决定了控制器变量名？是总是只是包含ID后跟Controller？

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

推荐答案

是的字段名称是注入控制器总是通过连接< fx：include> 标记的 fx：id 来构造code>控制器。

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

它在 FXMLLoader.CONTROLLER_SUFFIX 字段。

包含fxml文件的控制器的后缀。完整密钥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.

（命名空间映射包含按字段名称注入的所有对象to，如果存在这样的字段。）

你可以验证它的值是Controller此处： 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
