JavaFX WebView扩展到整个区域 [英] JavaFX WebView grow to fill entire area

问题描述

我正在尝试创建一个扩展到周围JPanel的javafx WebView。根据这个帖子：

请注意，场景有蓝色背景，所以你可以看到javafx的东西确实填满了整个JPanel。但是WebView没有填充javafx组/场景。

  import java.awt.BorderLayout; 
 
 import javax.swing.JButton; 
 import javax.swing.JFrame; 
 import javax.swing.JPanel; 
 import javax.swing.SwingUtilities; 
 
 import javafx.application.Platform; 
 import javafx.embed.swing.JFXPanel; 
 import javafx.scene.Group; 
 import javafx.scene.Scene; 
 import javafx.scene.layout.GridPane; 
 import javafx.scene.layout.Priority; 
 import javafx.scene.paint.Color; 
 import javafx.scene.web.WebEngine; 
 import javafx.scene.web.WebView; 
 
 
公共类Main {
 
 private void initAndShowGUI（）{
 //此方法在EDT线程
 JFrame框架上调用= new JFrame（Swing and JavaFX）; 
 frame.setSize（1000,1000）; 
 frame.setVisible（true）; 
 frame.setDefaultCloseOperation（JFrame.EXIT_ON_CLOSE）; 
 
 
 JPanel panel = new JPanel（new BorderLayout（0,0））; 
 frame.getContentPane（）。add（panel，BorderLayout.CENTER）; 
 
 JButton button = new JButton（button）; 
 panel.add（button，BorderLayout.CENTER）; 
 
 final JFXPanel fxPanel = new JFXPanel（）; 
 panel.add（fxPanel，BorderLayout.CENTER）; 
 
 
 Platform.runLater（new Runnable（）{
 @Override 
 public void run（）{
 initFX（fxPanel）; 
 } 
}）; 
} 
 
私有WebView webView; 
 
 private void initFX（JFXPanel fxPanel）{
 //此方法在JavaFX线程上调用
 Scene scene = createScene（）; 
 fxPanel.setScene（scene）; 
 
 GridPane.setHgrow（webView，Priority.ALWAYS）; 
 GridPane.setVgrow（webView，Priority.ALWAYS）; 
} 
 
 private Scene createScene（）{
 Group root = new Group（）; 
场景场景=新场景（root，Color.ALICEBLUE）; 
 
 webView = new WebView（）; 
 GridPane.setHgrow（webView，Priority.ALWAYS）; 
 GridPane.setVgrow（webView，Priority.ALWAYS）; 
 
 
 WebEngine webEngine = webView.getEngine（）; 
 webEngine.load（http://www.google.com）; 
 root.getChildren（）。add（webView）; 
 
 GridPane.setHgrow（webView，Priority.ALWAYS）; 
 GridPane.setVgrow（webView，Priority.ALWAYS）; 
 
返回场景; 
} 
 
 public static void main（String [] args）{
 SwingUtilities.invokeLater（new Runnable（）{
 @Override 
 public void run （）{
 new Main（）。initAndShowGUI（）; 
} 
}）; 
} 
} 
  

解决方案

一个方法是将 WebView 添加到

  import java.awt.BorderLayout; 
 import javax.swing.JFrame; 
 import javax.swing.SwingUtilities; 
 import javafx.application.Platform; 
 import javafx.embed.swing.JFXPanel; 
 import javafx.scene.Scene; 
 import javafx.scene.layout.StackPane; 
 import javafx.scene.web.WebEngine; 
 import javafx.scene.web.WebView; 
 
 / ** @see https://stackoverflow.com/a/31576647/230513 * / 
公共类WebViewTest {
 
 private void initAndShowGUI（）{ 
 //在EDT线程上调用此方法
 JFrame frame = new JFrame（Swing and JavaFX）; 
 frame.setDefaultCloseOperation（JFrame.EXIT_ON_CLOSE）; 
 final JFXPanel fxPanel = new JFXPanel（）{
 
 @Override 
 public Dimension getPreferredSize（）{
 return new Dimension（640,480）; 
} 
}; 
 frame.add（fxPanel，BorderLayout.CENTER）; 
 frame.pack（）; 
 frame.setLocationRelativeTo（null）; 
 frame.setVisible（true）; 
 
 Platform.runLater（（） - > {
 initFX（fxPanel）; 
}）; 
} 
 
 private void initFX（JFXPanel fxPanel）{
 //此方法在JavaFX线程上调用
场景场景= createScene（）; 
 fxPanel.setScene（scene）; 
} 
 
 private场景createScene（）{
 StackPane root = new StackPane（）; 
场景场景=新场景（根）; 
 WebView webView = new WebView（）; 
 WebEngine webEngine = webView.getEngine（）; 
 webEngine.load（http://www.example.com）; 
 root.getChildren（）。add（webView）; 
返回场景; 
} 
 
 public static void main（String [] args）{
 SwingUtilities.invokeLater（new WebViewTest（）:: initAndShowGUI）; 
} 
} 
  

I'm trying to make a javafx WebView that expands to the surrounding JPanel. According to this thread:

Note that the Scene has a blue background, so you can see that the javafx stuff does fill the entire JPanel. But the WebView does not fill the javafx Group/Scene.

import java.awt.BorderLayout;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.SwingUtilities;

import javafx.application.Platform;
import javafx.embed.swing.JFXPanel;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.layout.GridPane;
import javafx.scene.layout.Priority;
import javafx.scene.paint.Color;
import javafx.scene.web.WebEngine;
import javafx.scene.web.WebView;


public class Main {

    private void initAndShowGUI() {
        // This method is invoked on the EDT thread
        JFrame frame = new JFrame("Swing and JavaFX");
        frame.setSize(1000, 1000);
        frame.setVisible(true);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);


        JPanel panel = new JPanel(new BorderLayout(0, 0));
        frame.getContentPane().add(panel, BorderLayout.CENTER);

        JButton button = new JButton("button");
        panel.add(button, BorderLayout.CENTER);

        final JFXPanel fxPanel = new JFXPanel();
        panel.add(fxPanel, BorderLayout.CENTER);


        Platform.runLater(new Runnable() {
            @Override
            public void run() {
                initFX(fxPanel);
            }
       });
    }

    private WebView webView;

    private void initFX(JFXPanel fxPanel) {
        // This method is invoked on the JavaFX thread
        Scene scene = createScene();
        fxPanel.setScene(scene);

        GridPane.setHgrow(webView, Priority.ALWAYS);
        GridPane.setVgrow(webView, Priority.ALWAYS);
    }

    private Scene createScene() {
        Group root = new Group();
        Scene scene = new Scene(root, Color.ALICEBLUE);

        webView = new WebView();
        GridPane.setHgrow(webView, Priority.ALWAYS);
        GridPane.setVgrow(webView, Priority.ALWAYS);


        WebEngine webEngine = webView.getEngine();
        webEngine.load("http://www.google.com");
        root.getChildren().add(webView);

        GridPane.setHgrow(webView, Priority.ALWAYS);
        GridPane.setVgrow(webView, Priority.ALWAYS);

        return scene;
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            @Override
            public void run() {
                new Main().initAndShowGUI();
            }
        });
    }
}

解决方案

One approach is to add the WebView to a StackPane, which "will attempt to resize each child to fill its content area." I've given the enclosing JFXPanel to an arbitrary preferred size of 640 x 480; resize the frame to see how the StackPane reflows the WebView content based on the default Pos.CENTER.

import java.awt.BorderLayout;
import javax.swing.JFrame;
import javax.swing.SwingUtilities;
import javafx.application.Platform;
import javafx.embed.swing.JFXPanel;
import javafx.scene.Scene;
import javafx.scene.layout.StackPane;
import javafx.scene.web.WebEngine;
import javafx.scene.web.WebView;

/** @see https://stackoverflow.com/a/31576647/230513 */
public class WebViewTest {

    private void initAndShowGUI() {
        // This method is invoked on the EDT thread
        JFrame frame = new JFrame("Swing and JavaFX");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        final JFXPanel fxPanel = new JFXPanel(){

            @Override
            public Dimension getPreferredSize() {
                return new Dimension(640, 480);
            }
        };
        frame.add(fxPanel, BorderLayout.CENTER);
        frame.pack();
        frame.setLocationRelativeTo(null);
        frame.setVisible(true);

        Platform.runLater(() -> {
            initFX(fxPanel);
        });
    }

    private void initFX(JFXPanel fxPanel) {
        // This method is invoked on the JavaFX thread
        Scene scene = createScene();
        fxPanel.setScene(scene);
    }

    private Scene createScene() {
        StackPane root = new StackPane();
        Scene scene = new Scene(root);
        WebView  webView = new WebView();
        WebEngine webEngine = webView.getEngine();
        webEngine.load("http://www.example.com");
        root.getChildren().add(webView);
        return scene;
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new WebViewTest()::initAndShowGUI);
    }
}
