我正在创建一个简单的视频播放器,但我有问题显示要在JPanel中流式传输的视频文件.我创建并设计了一个JFrame,并在表单中放置了一个方形大小的JPanel.

到目前为止,这是我的代码:

package SoundsTrip;

import java.awt.BorderLayout;
import java.awt.Component;
import java.io.IOException;
import java.net.MalformedURLException;
import java.net.URL;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.media.CannotRealizeException;
import javax.media.Manager;
import javax.media.NoPlayerException;
import javax.media.Player;
import javax.swing.JFileChooser;
import javax.swing.JOptionPane;

/**

 * @author jmoreno
 */
public class VideoFrame extends javax.swing.JFrame {
    /** Creates new form VideoFrame */
    public VideoFrame() {
        initComponents();
        //this.setExtendedState(VideoFrame.MAXIMIZED_BOTH);
        this.setSize(650, 500);
    }

    /** This method is called from within the constructor to
     * initialize the form.
     * WARNING: Do NOT modify this code. The content of …

当我在其中按下带有for循环事件的jbutton时,其他组件被禁用.

这是我的jbutton代码:

    try{
        InetAddress localhost = InetAddress.getLocalHost();
        byte[] ip = localhost.getAddress();

        for(int i=1;i<254;i++){
            ip[3]=(byte)i;
            final InetAddress address = InetAddress.getByAddress(ip);

            if(address.isReachable(1000)){
                listModel1.addElement(address);
                System.out.println(address + "-Machine is turned on and can be ping.");
                Rectangle progressRec = jProgressBar1.getBounds();
                progressRec.x = 0;
                progressRec.y = 0;
                jProgressBar1.setValue(i);
                jProgressBar1.paintImmediately(progressRec);
            }
        }
        jList1.setModel(listModel1);
    }catch(Exception e){
        e.printStackTrace();
    }

循环结束后,其他组件是否已启用？我怎么去处理它？提前致谢...

编辑代码:建议不擅长编码

    try{
        InetAddress localhost = InetAddress.getLocalHost();
        final byte[] ip = localhost.getAddress();

        SwingWorker<ListModel, InetAddress> worker = new SwingWorker<ListModel, InetAddress>(){
            public ListModel doInBackground() throws UnknownHostException, IOException{
                for(int i=1;i<254;i++){
                    ip[3]=(byte)i;
                    final InetAddress …
