使用单独的场景替换TabPane（JAVAFX）

javajavafxcontrollerjavafx-8tabpanel
3

目前我有一个带有3个活动选项卡的TabPane。手动切换它们并不理想。我想要做的是完全替换TabPane，并在舞台中放置一个场景，然后在按下按钮时切换到下一个场景（从Tab1、到Tab2、再到Tab3）。

保持设置标签文本功能非常重要。

Tab1

Tab1

Tab2

Tab2

        primaryStage.setScene(new Scene(root, 300, 275));

这里是一个例子

fxml

创建3个面板，每个面板都有自己的按钮和标签

<?xml version="1.0" encoding="UTF-8"?>

<?import java.lang.*?>
<?import java.util.*?>
<?import javafx.scene.*?>
<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>

<AnchorPane id="AnchorPane" prefHeight="380.0" prefWidth="387.0" xmlns="http://javafx.com/javafx/8" xmlns:fx="http://javafx.com/fxml/1" fx:controller="ask.FXMLDocumentController">
   <children>
      <Pane fx:id="p3" prefHeight="380.0" prefWidth="387.0" visible="false">
         <children>
            <Label layoutX="184.0" layoutY="181.0" text="p3" />
            <Button fx:id="p3previous" layoutX="152.0" layoutY="225.0" mnemonicParsing="false" text="previous" />
         </children>
      </Pane>
      <Pane fx:id="p2" prefHeight="380.0" prefWidth="387.0" visible="false">
         <children>
            <Label layoutX="184.0" layoutY="181.0" text="p2" />
            <Button fx:id="p2previous" layoutX="78.0" layoutY="255.0" mnemonicParsing="false" text="previous" />
            <Button fx:id="p2next" layoutX="239.0" layoutY="255.0" mnemonicParsing="false" text="next" />
         </children>
      </Pane>
      <Pane fx:id="p1" prefHeight="380.0" prefWidth="387.0">
         <children>
            <Button fx:id="p1next" layoutX="167.0" layoutY="210.0" mnemonicParsing="false" text="next" />
            <Label layoutX="184.0" layoutY="181.0" text="p1" />
         </children>
      </Pane>
   </children>
</AnchorPane>

控制器

添加按钮动作事件，使用setVisible(boolean)来控制应该显示哪个面板。

import java.net.URL;
import java.util.ResourceBundle;
import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import javafx.scene.control.Button;
import javafx.scene.layout.Pane;

public class FXMLDocumentController implements Initializable {

    @FXML Pane p1;
    @FXML Pane p2;
    @FXML Pane p3;
    @FXML Button p1next;
    @FXML Button p2next;
    @FXML Button p2previous;
    @FXML Button p3previous;

    public void initialize(URL url, ResourceBundle rb) 
    {
        p1next.setOnAction(e->{ p1.setVisible(false); p2.setVisible(true); });
        p2next.setOnAction(e->{ p2.setVisible(false); p3.setVisible(true); });
        p2previous.setOnAction(e->{ p2.setVisible(false); p1.setVisible(true); });
        p3previous.setOnAction(e->{ p3.setVisible(false); p2.setVisible(true); });
    }  
}
嗨，感谢您的输入。您是否知道我如何为每个单独的面板添加@FXML文件，或者有更好的方法来编辑p1，p2和p3？ - Elion
这可能会有所帮助。https://dev59.com/v33aa4cB1Zd3GeqPZi5x - SedJ601
@Elion，请检查Fabian的答案。 - TomN
@TomN 是的，谢谢你们两个。我希望我能发出不止一个绿色对勾！案件已结。^.^ - Elion

您不需要将所有内容都添加到fxml文件中以在场景中进行显示。可以使用<fx:define>标签创建尚未成为对象场景的Node。请使用适当的Parent来正确显示内容。
<StackPane fx:id="container" prefHeight="432.0" prefWidth="443.0" xmlns="http://javafx.com/javafx/8.0.60" xmlns:fx="http://javafx.com/fxml/1" fx:controller="controller.MainController">
    <children>
        <fx:include fx:id="tab1" source="tab/Tab1.fxml" />
        <fx:define>
            <fx:include fx:id="tab2" source="tab/Tab2.fxml" />
            <fx:include fx:id="tab3" source="tab/Tab3.fxml" />
        </fx:define>
    </children>
</StackPane>


public class MainController {

    @FXML private Tab1Controller tab1Controller;
    @FXML private Tab2Controller tab2Controller;
    @FXML private Tab3Controller tab3Controller;

    @FXML private Node tab1;
    @FXML private Node tab2;
    @FXML private Node tab3;

    @FXML private StackPane container;

    public void initialize() {
        tab1Controller.init(this);
        tab2Controller.init(this);
        tab3Controller.init(this);
    }

    public void setTab2LabelText(String text) {
        tab3Controller.lbl3.setText(text);
        tab2Controller.lbl2.setText(text);
    }

    public void toTab2() {
        container.getChildren().setAll(tab2);
    }
}
谢谢！问题已解决。^_^ - Elion
