摆动游戏布局问题

Question

我正在实现分层窗格中的游戏，我遇到了一些布局问题。出于某种原因，没有正确排列。我最终在我的框架顶部留出了一个空白区域，并且框架永远不会扩展到正确的大小以适合所有内容。我已经尝试过frame.pack（），因为我之前已经做过（没有分层面板），但似乎也没有工作。

如果有人能帮助我，我会很感激。我有一种感觉，那就是我缺少的东西。

public class gameGUI extends JFrame{ 

//set up all the variables that will be used in the gameGUI 
static int skyWidth = 1024; 
static int skyHeight = 120; 
static int sidebarWidth = 120; 
static int sidebarHeight = 480; 
static int boardWidth = 904; 
static int boardHeight = 480; 
private JLayeredPane pane = new JLayeredPane(); 
public static YardDriver thisDriver; 
public static int getScreenWidth(){return boardWidth;} 
public static int getScreenHeight(){return boardHeight;} 

public JLayeredPane getPane(){ 
    return pane; 
} 


//Convert the width of the screen to work with the gui 
public int convertX(int rainLoc,BufferedImage img){ 
    int x = rainLoc % 30; 
    return ((boardWidth-img.getWidth())*x)/YardDriver.getScreenWidth(); 
} 

//Convert the height of the screen to work with the gui 
public int convertY(int rainLoc, BufferedImage img){ 
    int y = (rainLoc - (rainLoc % 30))/30;  
    return ((boardHeight-img.getHeight())*y)/YardDriver.getScreenWidth(); 
} 

//Convert the screen to the board 
public static int convertStoB(Point screenLoc){ 
    int y = ((screenLoc.y - skyHeight) * YardDriver.getScreenHeight())/boardHeight; 
    int x = ((screenLoc.x - sidebarWidth) * YardDriver.getScreenWidth())/boardWidth; 
    return x + y*YardDriver.getScreenWidth(); 
} 

private void loadAll() { 

} 

public gameGUI() { 
    loadAll(); 

    JPanel timer = new JPanel(); 
    //place the image in a jlabel and set bounds 
    timer.add(sky); 
    //Set preferredsize, border, and set opaque 
    timer.setPreferredSize(new Dimension(skyWidth,skyHeight)); 
    timer.setBounds(0, 0, skyWidth, skyHeight); 
    timer.setOpaque(true); 
    timer.setBorder(BorderFactory.createLineBorder(Color.BLACK,2)); 

    JPanel sidebar = new JPanel(); 
    sidebar.setBounds(0, skyHeight, sidebarWidth, sidebarHeight); 
    JButton nativeOne = new JButton(); 
    JButton nativeTwo = new JButton(); 
    JButton nativeThree = new JButton(); 
    JButton exoticOne = new JButton(); 
    JButton exoticTwo = new JButton(); 
    JButton exoticThree = new JButton(); 
    //Set the preferredsize and set a border 
    sidebar.setLayout(new GridLayout(6, 1)); 
    sidebar.setPreferredSize(new Dimension(sidebarWidth, sidebarHeight)); 
    //Add each button to the sidebar 
    sidebar.add(nativeOne); 
    sidebar.add(nativeTwo); 
    sidebar.add(nativeThree); 
    sidebar.add(exoticOne); 
    sidebar.add(exoticTwo); 
    sidebar.add(exoticThree); 
    sidebar.setBorder(BorderFactory.createLineBorder(Color.BLACK,2)); 

    JPanel board = new gamePanel(this); 
    board.setBounds(sidebarWidth, skyHeight, boardWidth, boardHeight); 
    board.setPreferredSize(new Dimension(904, 480)); 
    board.setBorder(BorderFactory.createLineBorder(Color.BLACK,2)); 

    timer.setVisible(true); 
    sidebar.setVisible(true); 
    board.setVisible(true); 

    pane.add(timer, new Integer(1)); 
    pane.add(sidebar, new Integer(1)); 
    pane.add(board, new Integer(1)); 
    pane.setBounds(0,0,1024, 600); 

    setTitle("Storm Watch"); 
    setSize(1024, 600); 
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
    //Pack the frame and set it to visible 
    setVisible(true); 
    setContentPane(pane); 

} 
    public static void main(String[] args){ 

     //Create a new frame with the createAndShowGUI 
     JFrame frame = new gameGUI(); 
    }

你忘了设置布局管理，做这样的事情：

this.pane.setLayout(new BorderLayout()); 
this.pane.add(timer, BorderLayout.PAGE_START); 
this.pane.add(sidebar, BorderLayout.LINE_START); 
this.pane.add(board, BorderLayout.CENTER);
