如何获得彩色线来区分文本字段数组 [英] how to get colored line to differentiate text field array in swing

问题描述

我开发了一个框架，我使用GridBagLayout来排列12X12的文本字段。即，帧上总共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。

I have developed one frame on which I used GridBagLayout to arrange textfields of 12X12. i.e., total 144 textfields on frame. Now I want to differentiate these text fields with colored line after each 3 columns and three rows as shown in the following diagram. I tried in many ways, but I couldn't find the solution. Please suggest. Below is the some part of my code. Thanks in advance.

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。

Please consider the each number as one textfield in diagram.

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));
            }
        }

推荐答案

你我们可以 JSeparator 或打破每个一组3x3字段进入单独的窗格并使用 LineBorder 。

You could us a JSeparator or, break each group of 3x3 fields into there own separate panes and use a LineBorder.

只要您正确设置了字段，就可以获得复合面板/ LineBorder 上班

So long as you've setup you fields properly, you should be able to get the compound panels/LineBorder to work

抱歉，它应该是 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，你需要弄清楚你是怎么做的d播种你的字段，但基本上，我只是传入你想要使用的字段（例如2D数组）。

Now, obviously, you need to figure out how you'd seed your fields, but basically, I'd just pass in the fields you want to be used (such as 2D array for example).

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++;

}
