在JFrame中绘制多行（最小9x9）
好的，现在就显示出来了。专家组被我绘制的专线所掩盖，我目前正在研究使用哪种布局。 BorderLayout似乎不像我想要的那样工作，但还有很多其他的尝试。感谢您的帮助，如果您有任何其他建议，我很乐意听到。
在我登录之前的另一个补充：我已经确定了GridLayout，因为我可以控制所有组件的大小，然后调整框架的大小以适应它们。现在我正在研究投入。如何从JPanel中的TextFields获取信息到JComponent中以用作数据？问题出现在靠近底部的JComponent类的paintComponent方法中。我将使用此解决方案来帮助项目的网络部分。
这是我到目前为止的代码：
import javax.swing.*;
import java.awt.*;
public class GoBoard extends JFrame
{
public static void main(String[] args)
{
Graphics g;
JFrame goframe=new JFrame("Go");
goframe.setDefaultCloseOperation(EXIT_ON_CLOSE);
goframe.setSize(600,700);
goframe.setLayout(new GridLayout());
JPanel panel=new JPanel();
JComponent component=new gocomponent();
panel.setBackground(Color.WHITE);
JButton passbutton=new JButton("Pass");
JButton sendbutton=new JButton("Send");
JLabel label=new JLabel("Enter the coordinates of the intesection you want to play on.");
JLabel label2=new JLabel("Click send, Or click pass");
JLabel blank=new JLabel(" ");
JLabel blank2=new JLabel(" ");
JTextField text1=new JTextField(10);
JTextField text2=new JTextField(10);
panel.add(label);
panel.add(label2);
panel.add(blank);
panel.add(blank2);
panel.add(passbutton);
panel.add(sendbutton);
panel.add(text1);
panel.add(text2);
component.setOpaque(false);
component.setSize(450,450);
component.setVisible(true);
goframe.add(component);
goframe.add(panel);
goframe.setVisible(true);
}
}
class gocomponent extends JComponent
{
public void paintComponent(Graphics g)
{
Graphics2D g2 = (Graphics2D) g;
for(int i=0;i<=9;i++)
{
drawhorizontal(g2, 0, i*50, 450, i*50);
drawvertical(g2, i*50, 0, i*50, 450);
}
drawpiece(g2, text1.getText(), text2.getText(), true);
}
public void drawhorizontal(Graphics2D g2, int x1, int y1, int x2, int y2)
{
g2.setColor(Color.black);
g2.drawLine(x1, y1, x2, y2);
}
public void drawvertical(Graphics2D g2, int x1, int y1, int x2, int y2)
{
g2.setColor(Color.black);
g2.drawLine(x1, y1, x2, y2);
}
public void drawpiece(Graphics2D g2, int x, int y, boolean player)
{
if(player==true)
{
g2.setColor(Color.black);
}
if(player==false)
{
g2.setColor(Color.white);
}
g2.fillOval(x, y, 10, 10);
}
}

我必须修改你的代码才能让它编译。我做了几处修改，为您的持续发展提供了一个起点。
这是我的Go Frame版本的样子。
所以，这是我所做的改变。
首先，必须始终通过调用SwingUtilities.invokeLater启动Swing应用程序。
public static void main(String[] args) {
SwingUtilities.invokeLater(new GoBoard());
}
其次，我将JFrame和JPanels的构建分离为单独的方法/类。这使您可以一次关注GUI的一部分。
这里是JFrame的代码。
public void run() {
JFrame goframe = new JFrame("Go");
goframe.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel mainPanel = new JPanel();
mainPanel.add(new GoPanel());
mainPanel.add(createButtonPanel());
goframe.add(mainPanel);
goframe.pack();
goframe.setLocationByPlatform(true);
goframe.setVisible(true);
}
这里是JPanel按钮的代码。我使用GridBagLayout来获取文本字段和按钮以更好地排列。
private JPanel createButtonPanel() {
JPanel panel = new JPanel();
panel.setBackground(Color.WHITE);
panel.setLayout(new GridBagLayout());
int gridy = 0;
JLabel label = new JLabel(
"Enter the coordinates of the intesection you want to play on.");
addComponent(panel, label, 0, gridy++, 2, 1,
normalInsets, GridBagConstraints.LINE_START,
GridBagConstraints.HORIZONTAL);
JLabel label2 = new JLabel("Click send, Or click pass");
addComponent(panel, label2, 0, gridy++, 2, 1,
normalInsets, GridBagConstraints.LINE_START,
GridBagConstraints.HORIZONTAL);
text1 = new JTextField(10);
addComponent(panel, text1, 0, gridy, 1, 1,
normalInsets, GridBagConstraints.LINE_START,
GridBagConstraints.HORIZONTAL);
text2 = new JTextField(10);
addComponent(panel, text2, 1, gridy++, 1, 1,
normalInsets, GridBagConstraints.LINE_START,
GridBagConstraints.HORIZONTAL);
JButton passbutton = new JButton("Pass");
addComponent(panel, passbutton, 0, gridy, 1, 1,
normalInsets, GridBagConstraints.LINE_START,
GridBagConstraints.HORIZONTAL);
JButton sendbutton = new JButton("Send");
addComponent(panel, sendbutton, 1, gridy++, 1, 1,
normalInsets, GridBagConstraints.LINE_START,
GridBagConstraints.HORIZONTAL);
return panel;
}
private void addComponent(Container container, Component component,
int gridx, int gridy, int gridwidth, int gridheight,
Insets insets, int anchor, int fill) {
GridBagConstraints gbc = new GridBagConstraints(gridx, gridy,
gridwidth, gridheight, 1.0D, 1.0D, anchor, fill,
insets, 0, 0);
container.add(component, gbc);
}
最后，这里是Go棋盘的课程。你将不得不在外面留出一些空间，这样一块完整的石头就会在第一点上画出来。
我几乎把你的代码留下了原样，除非你在某人进入石头坐标之前就不能画石头。
public class GoPanel extends JPanel {
private static final long serialVersionUID = -5957209004151437002L;
public GoPanel() {
this.setPreferredSize(new Dimension(451, 451));
}
@Override
public void paintComponent(Graphics g) {
Graphics2D g2 = (Graphics2D) g;
for (int i = 0; i <= 10; i++) {
drawhorizontal(g2, 0, i * 50, 450, i * 50);
drawvertical(g2, i * 50, 0, i * 50, 450);
}
String a = text1.getText();
String b = text2.getText();
if (a.equals("") || b.equals("")) {
} else {
int x = Integer.valueOf(text1.getText());
int y = Integer.valueOf(text2.getText());
drawpiece(g2, x, y, true);
}
}
public void drawhorizontal(Graphics2D g2, int x1, int y1, int x2, int y2) {
g2.setColor(Color.black);
g2.drawLine(x1, y1, x2, y2);
}
public void drawvertical(Graphics2D g2, int x1, int y1, int x2, int y2) {
g2.setColor(Color.black);
g2.drawLine(x1, y1, x2, y2);
}
public void drawpiece(Graphics2D g2, int x, int y, boolean player) {
if (player == true) {
g2.setColor(Color.black);
}
if (player == false) {
g2.setColor(Color.white);
}
g2.fillOval(x, y, 10, 10);
}
}
最后，这里是整个可运行的代码。我把这些类放在GoBoard类中，以便更容易粘贴。您应该将每个类放在一个单独的文件中。
