如何获得彩色线来区分文本字段数组

Question

我开发了一个框架,我使用GridBagLayout来安排12X12的文本字段.即框架上共有144个文本字段.现在我想在每个3列和3行之后用彩色线区分这些文本字段,如下图所示.我试过很多方面,但我找不到解决办法.请建议.下面是我的代码的一部分.提前致谢.

1 2 3 | 4 5 6 | 7 8 9 | 10 11 12
      |       |       |
1 2 3 | 4 5 6 | 7 8 9 | 10 11 12 
      |       |       |
1 2 3 | 4 5 6 | 7 8 9 | 10 11 12
-------------------------------    
1 2 3 | 4 5 6 | 7 8 9 | 10 11 12
      |       |       |
1 2 3 | 4 5 6 | 7 8 9 | 10 11 12
      |       |       |
1 2 3 | 4 5 6 | 7 8 9 | 10 11 12
--------------------------------    |
1 2 3 | 4 5 6................

请将每个数字视为图表中的一个文本字段.

JTextField jt[][]=new JTextField[12][12];


for(int i=0;i<jt.length;i++)
        {
            for(int j=0;j<jt.length;j++)
            {

                jt[i][j] = new JTextField(1);


                constraints.gridx=j;
                consraints.gridy=i;
                gridbag.setConstraints(jt[i][j],cons);
                c.add(jt[i][j]);
                                jt[i][j].setHorizontalAlignment(JTextField.CENTER);
                jt[i][j].setFont(new Font("TimesNewRoman",Font.BOLD,14));
                jt[i][j].setDocument(new JTextFieldLimit(2));
            }
        }

您可以使用JSeparator,或者将每组3x3字段分成单独的窗格并使用LineBorder.

只要您正确设置了字段,就应该能够使复合面板/ LineBorder工作

UPDATE

对不起,应该是MatteBorder:P

GridBagConstraints gbc = new GridBagConstraints();
gbc.fill = GridBagConstraints.BOTH;
gbc.gridx = 0;
gbc.gridy = 0;

for (int row = 0; row < 4; row++) {

    gbc.gridx = 0;

    add(buildGroup(0, 0, 1, 1), gbc);
    gbc.gridx++;
    add(buildGroup(0, 0, 1, 1), gbc);
    gbc.gridx++;
    add(buildGroup(0, 0, 1, 1), gbc);
    gbc.gridx++;
    add(buildGroup(0, 0, 1, 0), gbc);
    gbc.gridy++;

}

public JPanel buildGroup(int top, int left, int bottom, int right) {

    JPanel panel = new JPanel(new GridBagLayout());
    panel.setBorder(new MatteBorder(top, left, bottom, right, Color.RED));
    GridBagConstraints gbc = new GridBagConstraints();
    gbc.insets = new Insets(2, 2, 2, 2);
    gbc.fill = GridBagConstraints.HORIZONTAL;
    for (int row = 0; row < 3; row++) {
        for (int col = 0; col < 3; col++) {

            JTextField field = new JTextField(8);
            gbc.gridx = col;
            gbc.gridy = row;

            panel.add(field, gbc);

        }
    }

    return panel;

}

现在,显然,您需要弄清楚如何为字段设定种子,但基本上,我只是传入您想要使用的字段(例如2D数组).

或者使用分隔符:P

for (int row = 0; row < 9; row++) {

    gbc.gridwidth = 1;
    gbc.weightx = 0;

    int verSplit = 0;

    for (int col = 0; col < 12; col++) {

        gbc.gridx++;

        add(new JTextField(8), gbc);

        verSplit++;
        if (verSplit == 3) {

            verSplit = 0;

            gbc.gridx++;

            if (horSplit % 3 == 0) {

            gbc.gridheight = 3;
            gbc.fill = GridBagConstraints.VERTICAL;
            add(new JSeparator(JSeparator.VERTICAL), gbc);

            gbc.fill = GridBagConstraints.HORIZONTAL;
            gbc.gridheight = 1;

            }

        }

    }

    horSplit++;

    gbc.gridx = 0;

    if (horSplit == 3) {

        horSplit = 0;
        gbc.gridy++;
        gbc.gridwidth = GridBagConstraints.REMAINDER;
        gbc.weightx = 1;
        add(new JSeparator(JSeparator.HORIZONTAL), gbc);

    }

    gbc.gridy++;

}
