设计一个10按钮的Java程序,可以采用`GridBagLayout`代替`GridLayout`来创建一个两行一列的布局,因为`GridBagLayout`更灵活,可以适应不同大小的组件。而每个网格中使用`BorderLayout`作为内部布局,以下是简化的步骤:
1. 导入必要的包:
```java
import javax.swing.*;
import java.awt.*;
```
2. 创建主窗口类并设置布局管理器:
```java
public class TenButtonApp extends JFrame {
private GridBagLayout gridbagLayout;
private JPanel mainPanel;
public TenButtonApp() {
setTitle("10 Button Layout");
setSize(400, 400);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
// 初始化布局管理器
gridbagLayout = new GridBagLayout();
mainPanel = new JPanel(new BorderLayout());
setContentPane(mainPanel);
mainPanel.setLayout(gridbagLayout);
}
// 其他部分省略...
}
```
3. 创建按钮数组,并添加到`BorderLayout`容器中:
```java
private JButton[] buttons = new JButton[10];
for (int i = 0; i < 10; i++) {
JButton button = new JButton("Button " + (i+1));
button.setBorder(BorderFactory.createEmptyBorder(5, 5, 5, 5)); // 添加边框
JPanel innerPanel = new JPanel(new BorderLayout());
innerPanel.add(button, BorderLayout.CENTER); // 设置中心区域为按钮
// 将每个按钮面板添加到gridbagLayout中,这里假设一行四个按钮
GridBagConstraints gbc = new GridBagConstraints();
gbc.gridx = i % 4;
gbc.gridy = Math.floorDiv(i, 4);
gbc.gridwidth = (i % 4 == 3) ? GridBagConstraints.REMAINDER : 1;
gbc.gridheight = (Math.floorDiv(i, 4) == 1) ? GridBagConstraints.REMAINDER : 1;
mainPanel.add(innerPanel, gbc);
buttons[i] = button;
}
// 添加其他事件监听等逻辑...
```
