swing - 加载 jcef 浏览器窗口后无法切换 JPanels

Question

我正在尝试在我的 Swing 应用程序中使用 jcef 浏览器，但遇到了问题。
首先，我无法将 jcef 浏览器添加为 jFrame 上的 JPanel 组件。然后我尝试直接在 jframe 上添加
[代码]getContentPane().add(browser.getUIComponent(), BorderLayout.CENTER);[/code]

现在当浏览器窗口加载到 JFrame 中时，如果我想与其他 Jpanel 切换，那么它无法以任何方式工作
加载CEF浏览器后无法切换屏幕。任何人都可以指出我需要做什么。这是我的测试 jframe。

import org.cef.CefApp;
import org.cef.CefClient;
import org.cef.browser.CefBrowser;
import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;

public class CardLayoutTst extends JFrame {
static CefBrowser browser = null;
static CefClient client = null;
private static final long serialVersionUID = 1L;
private JPanel cardPanel, jp1, jp2, buttonPanel;
private JLabel jl1, jl2;
private JButton btn1, btn2;
private CardLayout cardLayout = new CardLayout();

public CardLayoutTst() {
    setTitle("Test med CardLayout");
    setSize(400, 300);
    cardPanel = new JPanel();
    buttonPanel = new JPanel();
    cardPanel.setLayout(cardLayout);
    jp1 = new JPanel();
    jp2 = new JPanel();
    jl1 = new JLabel("Card 1");
    jl2 = new JLabel("Card 2");
    jp1.add(jl1);
    jp2.add(jl2);
    cardPanel.add(jp1, "1");
    cardPanel.add(browser.getUIComponent(), "2");
    btn1 = new JButton("Show Card 1");
    btn1.addActionListener(new ActionListener() {

        public void actionPerformed(ActionEvent e) {
            cardLayout.show(cardPanel, "1");
        }
    });
    btn2 = new JButton("Show Card 2");
    btn2.addActionListener(new ActionListener() {

        public void actionPerformed(ActionEvent e) {
            cardLayout.show(cardPanel, "2");
        }
    });
    buttonPanel.add(btn1);
    buttonPanel.add(btn2);
    add(cardPanel, BorderLayout.NORTH);
    add(buttonPanel, BorderLayout.SOUTH);

    addWindowListener(new WindowAdapter() {
        @Override
        public void windowClosing(WindowEvent e) {
            CefApp.getInstance().dispose();
            dispose();
        }
    });

}

public static void main(String[] args) {
    client = CefApp.getInstance().createClient();
    browser = client.createBrowser("http://www.google.com", false, false);

    EventQueue.invokeLater(new Runnable() {
        @Override
        public void run() {
            CardLayoutTst frame = new CardLayoutTst();
            frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            frame.setVisible(true);
        }
    });
}

}

有点晚了，但我遇到了同样的问题。我的一个 friend 解决了这个问题。

您必须创建 CefSettings，将 windowless_rendering_enabled 设置为 false 并将此设置对象传递给 getInstance 调用:

CefSettings settings = new CefSettings();
settings.windowless_rendering_enabled = false;

client = CefApp.getInstance(settings).createClient();
