加载jcef浏览器窗口后无法切换JPanels
提问于 2015-06-22 13:09:53
我试图在我的swing应用程序中使用jcef浏览器，但是遇到了问题。首先，我无法将jcef浏览器作为JPanel组件添加到jFrame上。然后我尝试直接在jframe上添加代码(BorderLayout.CENTER)；/ codegetContentPane().add(browser.getUIComponent()，
现在，当浏览器窗口加载到JFrame中，如果我想切换到其他Jpanel，那么它不能以任何方式工作，我无法在加载CEF浏览器后切换屏幕。谁能指出我需要做什么。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);
}
});
}}

现在有点晚了，但我也有同样的问题。我的一个朋友解决了这个问题。
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();页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
