java - 如何在启动后将jBrowser添加到框架中？

Question

我有一个 Starter 类，它运行我的应用程序:

public class Starter {  
    public static Panel createContent() {
          Panel contentPane = new Panel();
          final JWebBrowser webBrowser = new JWebBrowser();
          webBrowser.navigate("http://orientalcraft.org/");
          webBrowser.setBarsVisible(false);   
          webBrowser.setStatusBarVisible(false);  
          contentPane.add(webBrowser);
          return contentPane;

      }

    public static void main(String[] args) throws IOException, Exception
    {
        Frame.go();
        NativeInterface.open();
        SwingUtilities.invokeLater(new Runnable() {
            @Override
            public void run() {

                Frame frame = Frame.mainFrame; //mainFrame - instance of Frame
                frame.getContentPane().add(createContent(), BorderLayout.CENTER);
            }

        });

        NativeInterface.runEventPump();   
    }
}

当我尝试将 jBrowser 添加到 Frame 时，我看不到任何关于 jBrowser 的信息。但是我可以在控制台中看到这个:

java.net.SocketException: Connection reset
    at java.net.SocketInputStream.read(SocketInputStream.java:196)  at java.net.SocketInputStream.read(SocketInputStream.java:196)

请帮我将 jBrowser 添加到现有 jFrame..

Answer 1

Please, help me to add a jBrowser to existing jFrame..

当您向可见 GUI 添加(或删除)组件时，基本代码是:

panel.add(...);
panel.revalidate();
panel.repaint();

以上内容适用于您所质疑的 Swing，但示例代码似乎使用的是 Frame 而不是 JFrame。尝试使用 JFrame。或者对于 AWT，我认为您会使用 validate()。
