java-如何获取彩色线条以区分挥杆中的文本字段数组
作者：互联网
我开发了一个框架,在该框架上使用GridBagLayout来排列12X12的文本字段.即框架上共有144个文本字段.现在,我想用每三列三行之后的彩色线来区分这些文本字段,如下图所示.我尝试了很多方法,但是找不到解决方案.请提出建议.以下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................

请在图表中将每个数字视为一个文本字段.
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));
}
}
解决方法:
您可以给我们一个JSeparator,或者将每组3×3字段分成单独的窗格,然后使用LineBorder.
只要正确设置了字段,您就应该能够使复合面板/ LineBorder正常工作
UPDATE
抱歉,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,您需要弄清楚如何对字段进行播种,但是基本上,我只是传递要使用的字段(例如2D数组).
或带分隔符：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++;
}

// Build the array of fields, I used a col by row matrix

}
// Build the groups...
