我尝试将两个jpanels并排放置,但是在这一刻我不能做我想要的,我有这个代码,

this.videoPanel= new JPanel();
this.videoPanel.setBackground(new Color(102, 102, 102));
this.videoPanel.setPreferredSize(new Dimension(320, 240));
this.videoPanel.setLayout(new BoxLayout(this.videoPanel, 1));

GroupLayout layout = new GroupLayout(getContentPane());
getContentPane().setLayout(layout);

layout.setHorizontalGroup(
        layout.createSequentialGroup()
        .addGroup(layout.createParallelGroup(GroupLayout.Alignment.LEADING)
        .addComponent(this.videoPanel, 10, 400, 500)));

layout.setVerticalGroup(
        layout.createSequentialGroup()
        .addGroup(layout.createParallelGroup(GroupLayout.Alignment.BASELINE)
        .addComponent(this.videoPanel, 10, 400, 500)));

pack();

`我试着再放一个jpanel:

 this.videoPanel1.setBackground(new Color(102, 102, 102));
 this.videoPanel1.setPreferredSize(new Dimension(320, 240));
 this.videoPanel1.setLayout(new BoxLayout(this.videoPanel1, 2));

 GroupLayout layout = new GroupLayout(getContentPane());
 getContentPane().setLayout(layout);



 layout.setHorizontalGroup(
         layout.createSequentialGroup()
         .addGroup(layout.createParallelGroup(GroupLayout.Alignment.LEADING)
         .addComponent(this.videoPanel1, 10, 400, 500)
         .addComponent(this.videoPanel, 10, 400, 500)));

 layout.setVerticalGroup(
         layout.createSequentialGroup()
         .addGroup(layout.createParallelGroup(GroupLayout.Alignment.BASELINE)
         .addComponent(this.videoPanel1, 10, 400, 500)
         .addComponent(this.videoPanel, 10, 400, 500)));
      pack();

此代码不起作用,也不会出错.
