被控件折腾的够呛啊，大家帮我看一下
下面是我用NetBean生成的控件代码，其中的JTextField变量TSearch没法输入，即使我显示光标并且获取输入焦点，找了好久，什么都试了，还是不行，还有JList变量LSongList显示出来后垂直滚动条都没法用，不知道为什么，我在相应部分做了注释，望大家帮我看一下，实在是搞不明白。
程序代码：public class MP3Player extends javax.swing.JFrame {
Player player; //播放器
String mediaLocation;
String urlLocation;
MediaTracker mediaTracker=new MediaTracker(this);
boolean useDefaultImage=true;
Image urlImage;
boolean isFile=true;
boolean playing=false;
boolean pause=true;
boolean stop=true;
class TexPicPanel extends JPanel{
public void setBackgroundImage(){
repaint();
}
protected void paintComponent(Graphics g){
if(useDefaultImage){
ImageIcon imageIcon=new ImageIcon("src\\pic\\背景图片.jpg");
Image image =new ImageIcon("src\\pic\\背景图片.jpg").getImage();
g.drawImage((Image)image,0,0,PSelPlay.getSize().width,
PSelPlay.getSize().height,0,0,imageIcon.getIconWidth(),imageIcon.getIconHeight(),this);
PSelPlay.setVisible(true);
PSelPlay.setOpaque(false);
String content=new String("正在为您搜索网络图片..........");
JLabel lyric=new JLabel(content,null,JLabel.CENTER);
lyric.setFont(new Font("仿宋_GB2312", 0, 30));
lyric.setSize(PSelPlay.getSize().width,PSelPlay.getSize().height);
lyric.setOpaque(false);
lyric.setVisible(true);
PSelPlay.add(lyric);
}
else
{
g.drawImage(urlImage,0,0,PSelPlay.getSize().width,PSelPlay.getSize().height,this);
}
}

System.out.println("调用update");
Image image=new ImageIcon("D:\\Java\\MP3Player\\MP3Player\\src\\pic\\酷我.jpg").getImage();
g.drawImage(image,0,0, this);
} */
