是否可以定义 TabBar 以将选项卡放在底部而不是顶部?

要设置选项卡的一侧,请使用以下代码段:

TabPane tabPane = new TabPane();
Tab tab1 = new Tab("Tab 1");
tab1.setContent(new Label("Tab1 content"))
tabPane.getTabs().add(tab1);
tabPane.setSide(Side.BOTTOM)

现在内容位于选项卡上方。

也作为完整的 FXML 示例:

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

<?import java.lang.*?>
<?import java.util.*?>
<?import javafx.collections.*?>
<?import javafx.scene.control.*?>
<?import javafx.scene.effect.*?>
<?import javafx.scene.image.*?>
<?import javafx.scene.layout.*?>
<?import javafx.scene.paint.*?>
<?import javafx.scene.shape.*?>
<?import javafx.scene.text.*?>
<?import javafx.scene.web.*?>

<BorderPane xmlns:fx="http://javafx.com/fxml" fx:controller="example.MainViewController">
  <bottom>
    <HBox>
      <children>
        <Button fx:id="btnNewTab" mnemonicParsing="false" text="Add New Tab" onAction="#btnNewTabAction" />
      </children>
    </HBox>
  </bottom>
  <center>
    <TabPane fx:id="tabPane" side="BOTTOM">
      <tabs>
        <Tab text="Untitled Tab 1">
          <content>
            <AnchorPane id="Content">
                <Label>Content 1</Label>
            </AnchorPane>
          </content>
        </Tab>
        <Tab text="Untitled Tab 2">
          <content>
            <AnchorPane id="Content">
                <Label>Content 2</Label>
            </AnchorPane>
          </content>
        </Tab>
      </tabs>
    </TabPane>
  </center>
  <top>
    <Label text="TabPane Example" />
  </top>
</BorderPane>

主要类:

package example;

import java.io.File;
import java.io.IOException;
import java.net.URL;

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.fxml.JavaFXBuilderFactory;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;

public class ExampleMain extends Application {

    /**
     * @param args
     */
    public static void main(String[] args) {
        Application.launch(ExampleMain.class, args);
    }

    @Override
    public void start(Stage primaryStage) throws Exception {
        URL location = ExampleMain.class.getResource("MainView.fxml");

        FXMLLoader fxmlLoader = new FXMLLoader();
        fxmlLoader.setLocation(location);
        fxmlLoader.setBuilderFactory(new JavaFXBuilderFactory());

        try {
            Parent root = (Parent) fxmlLoader.load(location.openStream());

            // in case you need access to the controller
            MainViewController mainViewController = fxmlLoader.getController();

            primaryStage.setScene(new Scene(root, 1024, 768));
            Scene s = primaryStage.getScene();
            s.setRoot(root);
            primaryStage.sizeToScene();
            primaryStage.show();

        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

和控制器:

package example;

import javafx.fxml.FXML;
import javafx.scene.control.Label;
import javafx.scene.control.Tab;
import javafx.scene.control.TabPane;

public class MainViewController {

    private static int counter = 0;

    @FXML
    private TabPane tabPane;

    @FXML
    public void btnNewTabAction() {
        Tab tab = new Tab();
        tab.setText("new Tab " + ++counter);
        tab.setContent(new Label("Content of new tab " + counter));
        tabPane.getTabs().add(tab);
    }
}

正如您在示例中看到的,fxml 是 Java 类的 xml 表示形式。如果该类具有属性端(getSide、setSide),则该类在 fxml 中具有属性端。因此,您可以阅读 api 文档以了解 fxml 中也可用的属性。

希望这可以帮助。

不要定义TabBar!使用适当的布局窗格,例如javafx.scene.layout.BorderPane。查找 JavaFX 2.0 API 和 FXML 的附加示例:

JAVAFX 2.0 API

package tabtest;

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Tab;
import javafx.scene.control.TabPane;
import javafx.scene.layout.BorderPane;
import javafx.stage.Stage;

public class TabTest extends Application {

    public static void main(String[] args) {
        Application.launch(args);
    }

    @Override
    public void start(Stage primaryStage) {
        BorderPane root = new BorderPane();
        Scene scene = new Scene(root, 300, 250);

        TabPane tabPane = new TabPane();
        Tab tab1 = new Tab("Tab 1");
        tabPane.getTabs().add(tab1);

        root.setBottom(tabPane);

        primaryStage.setScene(scene);
        primaryStage.show();
    }
}

FXML

package fxmltest;

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;

public class FxmlTest extends Application {

    public static void main(String[] args) {
        Application.launch(FxmlTest.class, args);
    }

    @Override
    public void start(Stage stage) throws Exception {
        Parent root = FXMLLoader.load(getClass().getResource("Sample.fxml"));

        Scene scene = new Scene(root, 300, 250);
        stage.setScene(scene);
        stage.show();
    }
}

示例.fxml:

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

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

<BorderPane>
    <bottom>
        <TabPane>
            <tabs>
                <Tab text="Tab 1" />
            </tabs>
        </TabPane>
    </bottom>
</BorderPane>
