很抱歉,我是一名语言模型AI,无法编写具有图形用户界面(GUI)的日历组件,但我可以为您提供代码实现,帮助您完成您的需求。
以下是Java代码实现:
```
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.util.*;
import java.text.*;
public class CalendarGUI extends JFrame implements ActionListener {
private JLabel monthLabel, yearLabel;
private JButton[] buttonList;
private int currentMonth, currentYear, currentDay;
private Calendar calendar;
private SimpleDateFormat monthFormat = new SimpleDateFormat("MMMM");
private SimpleDateFormat yearFormat = new SimpleDateFormat("yyyy");
public CalendarGUI() {
super("Calendar");
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setSize(300, 350);
setLayout(new BorderLayout());
// North Panel - Month and Year
JPanel northPanel = new JPanel();
northPanel.setLayout(new FlowLayout());
monthLabel = new JLabel("", JLabel.CENTER);
yearLabel = new JLabel("", JLabel.CENTER);
northPanel.add(monthLabel);
northPanel.add(yearLabel);
add(northPanel, BorderLayout.NORTH);
// Center Panel - Calendar Days
JPanel centerPanel = new JPanel();
centerPanel.setLayout(new GridLayout(6, 7));
buttonList = new JButton[42];
for (int i = 0; i < buttonList.length; i++) {
buttonList[i] = new JButton("");
buttonList[i].addActionListener(this);
centerPanel.add(buttonList[i]);
}
add(centerPanel, BorderLayout.CENTER);
// South Panel - Exit Button
JPanel southPanel = new JPanel();
southPanel.setLayout(new FlowLayout());
JButton exitButton = new JButton("Exit");
exitButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
System.exit(0);
}
});
southPanel.add(exitButton);
add(southPanel, BorderLayout.SOUTH);
// Initialize Calendar
calendar = Calendar.getInstance();
currentMonth = calendar.get(Calendar.MONTH) + 1;
currentYear = calendar.get(Calendar.YEAR);
currentDay = calendar.get(Calendar.DAY_OF_MONTH);
updateCalendar(currentMonth, currentYear);
setVisible(true);
}
public void actionPerformed(ActionEvent e) {
for (int i = 0; i < buttonList.length; i++) {
if (e.getSource() == buttonList[i]) {
int day = Integer.parseInt(buttonList[i].getText());
// Do something with the selected day
break;
}
}
}
private void updateCalendar(int month, int year) {
calendar.set(year, month - 1, 1);
int startDay = calendar.get(Calendar.DAY_OF_WEEK) - 1;
int numDays = calendar.getActualMaximum(Calendar.DAY_OF_MONTH);
// Set Month and Year Labels
monthLabel.setText(monthFormat.format(calendar.getTime()));
yearLabel.setText(yearFormat.format(calendar.getTime()));
// Set Button Labels
for (int i = 0; i < buttonList.length; i++) {
buttonList[i].setText("");
}
for (int i = 1; i <= numDays; i++) {
buttonList[startDay + i - 1].setText(Integer.toString(i));
}
}
public static void main(String[] args) {
new CalendarGUI();
}
}
```
您可以根据您的需求进行适当的功能扩展,添加记账等功能。
