制定一个大小的Jpanel里面装两个list，list的大小怎么是固定的
让我很理解，我用setbounds setsize都没有用
很奇怪
！有人知道什么鸢鹰吗？
我把部分代码贴一下，由于是一个播放器，不能全贴看不懂！
listPanel = new JPanel();
        listPanel.setLayout(new BorderLayout());
        listPanel.setBounds(new Rectangle(4,150,289,148));
        listPanel.setBorder(BorderFactory.createEtchedBorder());
        leftList = new List();
        leftList.setBounds(new Rectangle(4,150,100,148));
        //leftList.setLocation(4, 150);
        //leftList.setSize(new Dimension(100,148));
        listPanel.add(new JScrollPane(leftList),BorderLayout.WEST);
        playList = new List();
        playList.setBounds(new Rectangle(100, 150, 189, 148));
        playList.addMouseListener(new MouseAdapter(){
            public void mouseClicked(MouseEvent e) {
                if(e.getClickCount() == 2){
                    playState();
                }
            }
        });
        listPanel.add(new JScrollPane(playList),BorderLayout.EAST);
        cp.add(listPanel);
        split = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT,true,leftList,playList);
        split.setBorder(new EmptyBorder(0,0,0,0));
        listPanel.add(split);

你应该把JScrollPane来setBounds

playListTitle = new JLabel();
        playListTitle.setBounds(new Rectangle(5,135,100,20));
        playListTitle.setText("PLAYLIST");
        cp.add(playListTitle);
        listPanel = new JPanel();
        listPanel.setLayout(new BorderLayout());
        //listPanel.setLayout(new FlowLayout());
        listPanel.setBounds(new Rectangle(4,150,289,148));
        listPanel.setBorder(BorderFactory.createEtchedBorder());
        leftList = new List();
        //leftList.setLocation(4, 150);
        //leftList.setBounds(new Rectangle(4,150,100,148));
        //leftList.setLocation(4, 150);
        //leftList.setSize(new Dimension(100,148));
        leftJScrollPanel = new JScrollPane(leftList);
        listPanel.add(leftJScrollPanel);
        playList = new List();
        playJScrollPanel = new JScrollPane(playList);
        playJScrollPanel .setBounds(new Rectangle(100, 150, 189, 148));
        playList.addMouseListener(new MouseAdapter(){
            public void mouseClicked(MouseEvent e) {
                if(e.getClickCount() == 2){
                    playState();
                }
            }
        });
        listPanel.add(playJScrollPanel);
        cp.add(listPanel);
        split = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT,true,leftJScrollPanel,playJScrollPanel );
        split.setBorder(new EmptyBorder(0,0,0,0));
        listPanel.add(split);

还是不行，感觉左边一个list大小定死了，拉过去的时候大小还是原来的一半！

往右边能拉，左边就脱不动了，大小是固定的，哪里出了问题？

往左拉会出现这种情况！

而且每次运行都不太一样
