JavaFx TabPane：想要一个控制器用于 2 个或更多选项卡
JavaFx TabPane : Want One Controller For 2 or more tab
我是 java Fx 的新手。我有一个带有 3 个选项卡的 TabPanel。每个选项卡都有很多控件（文本、按钮等），而我想要的是为所有选项卡分配一个控制器。 SceneBuilder 只让我为整个视图分配一个控制器，我的意思是，只有顶部面板（根）有 "Controller class" 选项，所以如何在一个 class 中编写所有选项卡的代码.
我有 .fxml 文件为：
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.control.*?>
<?import java.lang.*?>
<?import javafx.scene.layout.*?>
<?import javafx.scene.layout.AnchorPane?>
<Pane lns="http://javafx.com/javafx/8"xmlns:fx="http://javafx.com/fxml/1"
fx:controller="Application.LoginController">
<children>
<TabPane maxHeight="-Infinity" maxWidth="-Infinity" minHeight=" -
Infinity" minWidth="-Infinity" prefHeight="400.0" prefWidth="600.0"
tabClosingPolicy="UNAVAILABLE">
<tabs>
<Tab text="Register">

<AnchorPane minHeight="0.0" minWidth="0.0" prefHeight="180.0"
prefWidth="200.0">
<children>
<Label layoutX="27.0" layoutY="45.0" text="Name" />
<Label layoutX="27.0" layoutY="102.0" text="Password"

<Label layoutX="27.0" layoutY="151.0" text="City" />
<Label layoutX="27.0" layoutY="204.0" text="Email" />
<Label layoutX="27.0" layoutY="246.0" text="Phone" />

<Button fx:id="cancle" cancelButton="true"

<TextField fx:id="pwd" layoutX="148.0" layoutY="99.0"

您必须为选项卡创建一个新的 .fxml 文件然后设置 fx:controller=TabController 然后您可以 <fx:include source="myTab.fxml">
所以你可以包含这个 3 次然后你将有三个带有 sam 控制器的选项卡。
所以主要.fxml:
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.control.TabPane?>
<TabPane xmlns="http://javafx.com/javafx"
xmlns:fx="http://javafx.com/fxml"
fx:controller="TabPaneController">
<tabs>
<fx:include fx:id="FirstTab" source="CustomTab.fxml"/>
<fx:include fx:id="SecondTab" source="CustomTab.fxml"/>
<fx:include fx:id="ThirdTab" source="CustomTab.fxml"/>
</tabs>
</TabPane
>
和 child .fxml
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.control.Tab?>
<Tab xmlns="http://javafx.com/javafx"
xmlns:fx="http://javafx.com/fxml"
fx:controller="TabController">
<!--content-->
</Tab>
所以现在你有三个相同的选项卡 Controller。
此应用程序演示了如何使用控制器与 TabPane 中不同 Tab 中的不同 Node 交互。
