JavaFX超链接

Hyperlink类表示类似于JavaFX的网页上的锚链接的超链接。

import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.Hyperlink;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;
public class Main extends Application {
    @Override
    public void start(Stage stage) {
        stage.setTitle("HTML");
        stage.setWidth(500);
        stage.setHeight(500);
        Scene scene = new Scene(new Group());
        VBox root = new VBox();
        Hyperlink link = new Hyperlink("www.baidu.com");
        root.getChildren().addAll(link);
        scene.setRoot(root);
        stage.setScene(scene);
        stage.show();
    }
    public static void main(String[] args) {
        launch(args);
    }
}

package com.javafx05;
import java.awt.Desktop;
import java.io.IOException;
import java.net.URI;
import java.net.URISyntaxException;
import javafx.application.Application;
import javafx.beans.value.ChangeListener;
import javafx.beans.value.ObservableValue;
import javafx.stage.Stage;
import javafx.scene.Scene;
import javafx.scene.control.ScrollPane;
import javafx.scene.layout.AnchorPane;
import javafx.scene.web.WebView;
public class JavaFx11 extends Application {
    @Override
    public void start(Stage primaryStage) {
        try {
            String mInitUrl = "https://www.baidu.com";
            AnchorPane root = new AnchorPane();
            Scene scene = new Scene(root);
            WebView mWebView = new WebView();
            mWebView.getEngine().load(mInitUrl);
            mWebView.getEngine().locationProperty().addListener(new ChangeListener<String>() {
                @Override
                public void changed(ObservableValue<? extends String> observable, String oldValue, String newValue) {
                    Desktop d = Desktop.getDesktop();
                    URI address;
                    try {
                        if(!observable.getValue().contentEquals(mInitUrl)){
                            address = new URI(observable.getValue());
                            d.browse(address);
                        }
                    } catch (URISyntaxException | IOException e) {
                        e.printStackTrace();
                    }
                }
            });
            root.getChildren().add(mWebView);
            primaryStage.setScene(scene);
            primaryStage.show();
        } catch(Exception e) {
            e.printStackTrace();
        }
    }
    public static void main(String[] args) {
        launch(args);
    }
}

创建超链接

以下代码使用默认构造函数创建超链接对象。然后它设置一个URL作为文本标题，最后添加点击事件处理程序。

Hyperlink link = new Hyperlink();
link.setText("http://www.baidu.com");
link.setOnAction(e -> System.out.println("This link is clicked"));

示例

更改超链接的字体，如下代码所示 -

import java.io.File;
import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.Hyperlink;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.layout.VBox;
import javafx.scene.text.Font;
import javafx.stage.Stage;
public class Main extends Application {
    @Override
    public void start(Stage stage) {
        stage.setTitle("HTML");
        stage.setWidth(500);
        stage.setHeight(500);
        Scene scene = new Scene(new Group());
        VBox root = new VBox();    
        Hyperlink hpl = new Hyperlink("www.baidu.com");
        hpl.setFont(Font.font("Arial", 50));
        root.getChildren().addAll(hpl);
        scene.setRoot(root);
        stage.setScene(scene);
        stage.show();
    }
    public static void main(String[] args) {
        launch(args);
    }
}
