Question

美好的一天 -

我正在处理JApplets我有两个tabbedPanel。现在对于第一个tabbed我需要进一步将父JPanel分成两部分。为此，我创建了两个子面板，并使用JSplitPane类将它们分成两部分。

eastPanel
westPanel

窗口如下所示：

这是Resizeable因为我们可以看到最大化按钮已启用。我尝试设置此方法 setResizeable() ，但我认为它仅适用于JFRAME。

我尝试创建的所需UI如下：

我需要的是限制其大小，使其不再最大化，内容放在JPanel中。你能指导一下我应该遵循哪种方法来达到预期的效果吗？此外，来源如下：

    public class CreatePanel extends JPanel
 {
   private Vector athleteList;
   private JButton button1;
   private CountPanel cPanel;
   private TextField firstName;
   private TextArea textArea;
 //Constructor initializes components and organize them using certain layouts
 public CreatePanel(Vector athleteList, CountPanel cPanel)
  {
    this.athleteList = athleteList;
    this.cPanel = cPanel;

    //inner Jpanels to Split the parent panel
    JPanel eastPanel = new JPanel();
    JPanel westPanel = new JPanel();

    button1 = new JButton("Create an Athlete");
    textArea = new TextArea("No Athlete");
    textArea.setEditable(false);

    eastPanel.setBackground(Color.RED);
    westPanel.setBackground(Color.BLUE);
    eastPanel.add(button1);
    /* p1.add(firstName);
    p2.add(textArea);*/

    JSplitPane sp = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT);
    sp.setResizeWeight(0.5);
    sp.setDividerSize(0);
    sp.add(eastPanel);
    sp.add(westPanel);
    //organize components here
    setLayout( new GridLayout(1, 2));    

//    add(firstName,BorderLayout.WEST);
    add(sp);


  }


  //ButtonListener is a listener class that listens to
  //see if the button "Create an Athlete" is pushed.
  //When the event occurs, it adds an athlete using the information
  //entered by a user.
  //It also performs error checking.
  private class ButtonListener implements ActionListener
   {
    public void actionPerformed(ActionEvent event)
     {

         //TO BE COMPLETED

     } //end of actionPerformed method
  } //end of ButtonListener class

}

DriveClass

public class Test extends JApplet
 {

   private int APPLET_WIDTH = 500, APPLET_HEIGHT = 400;

   private JTabbedPane tPane;
   private CreatePanel createPanel;
   private CountPanel countPanel;
   private Vector athleteList;

   //The method init initializes the Applet with a Pane with two tabs
   public void init()
    {
     //list of athletes to be used in every panel
    athleteList = new Vector();

     //register panel uses the list of athletes
     countPanel = new CountPanel(athleteList);

     createPanel = new CreatePanel(athleteList, countPanel);

     //create a tabbed pane with two tabs
     tPane = new JTabbedPane();
     tPane.addTab("Athlete Creation", createPanel);
     tPane.addTab("Medal Count", countPanel);
     getContentPane().add(tPane);
     setSize (APPLET_WIDTH, APPLET_HEIGHT); //set Applet size
     setPreferredSize(new Dimension(APPLET_WIDTH, APPLET_HEIGHT));
     setMaximumSize(this.getPreferredSize());
     setMinimumSize(this.getPreferredSize());
    }
}

帮助将不胜感激。非常感谢
