大家好,我是Java编程ID的初学者,喜欢在这里问一些有经验的编码员。因此我尝试制作一个库存系统,但是布局Image Link出现问题。“年度余额”面板必须在“销售记录”面板下方,然后“销售记录”面板必须填充该空间水平上方。任何人都有什么问题的想法。

public MainViewForm(String text)
{



       setTitle("Computer Warehouse ni SeQuoia");  
       setLayout(new GridBagLayout());
       setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
       setSize(1200,900);        
       setResizable(true);
       setVisible(true);



       mBar = new JMenuBar();
        setJMenuBar(mBar);

       mFile = new JMenu("FILE");
    mBar.add(mFile);

    mEdit = new JMenu("EDIT");
    mBar.add(mEdit);

    mView = new JMenu("VIEW");
    mBar.add(mView);

    mSave = new JMenu("SAVE");
    mBar.add(mSave);

    tBSave = new JToggleButton("SAVE");
    mSave.add(tBSave);

    mHelp = new JMenu("HELP");
    mBar.add(mHelp);

     mOption = new JMenu("OPTION");
     mBar.add(mOption);

     mEnd = new JMenu("END");
     mBar.add(mEnd);

     tbExit = new JToggleButton("EXIT");
     mEnd.add(tbExit);


   dlyForm = new DailyForm();
   mtlyForm = new MonthlyForm();
   tForm = new TableForm();
   abForm = new AnnualBalanceForm();

   GridBagConstraints gbc_dlyForm = new GridBagConstraints();
   gbc_dlyForm.anchor=GridBagConstraints.FIRST_LINE_START;
   gbc_dlyForm.weightx=1;
   gbc_dlyForm.weighty=1;
   gbc_dlyForm.gridx=0;
   gbc_dlyForm.gridy=0;
   add(dlyForm,gbc_dlyForm );

   GridBagConstraints gbc_mtlyForm = new GridBagConstraints();
   gbc_mtlyForm.weightx=1;
   gbc_mtlyForm.weighty=1;
   gbc_mtlyForm.gridx=0;
   gbc_mtlyForm.gridy=0;
   gbc_mtlyForm.insets=new Insets(225,0,0,0);
   gbc_mtlyForm.anchor=GridBagConstraints.LINE_START;
   add(mtlyForm,gbc_mtlyForm);

   GridBagConstraints gbc_tForm = new GridBagConstraints();
   gbc_tForm.fill=GridBagConstraints.HORIZONTAL;
   gbc_tForm.weightx=0.1;
   gbc_tForm.weighty=0.1;
   gbc_tForm.anchor= GridBagConstraints.CENTER;
   add(tForm,gbc_tForm);

   GridBagConstraints gbc_abForm = new GridBagConstraints();
   gbc_abForm.anchor= GridBagConstraints.PAGE_END;
   gbc_abForm.weightx=1;
   gbc_abForm.weighty=1;

   add(abForm,gbc_abForm);

   pack();
}

答案 0 :(得分:1)

您尚未为这些约束指定gridx / gridy。它们默认为RELATIVE,因此下一个分量在水平和垂直方向上都将移动。

(如果我最想更改您的代码的一件事,那就是命名。我不在乎类型(使用名称),因此请删除该类型,并且不要缩写其余有用的词。同样值得注意的是GridBagConstraints数据已被复制,因此您可以在适当的地方重用它们。)
