Question

我正在尝试使用Swing在Java中创建日历界面，类似于Google日历中的每周视图，如下所示：

https://github.com/json-ld/json-ld.org/issues/311

这是我到目前为止创建的日历的图像：

目前我已经创建了一个名为GridPanel的类，它只是一个JPanel容器，用于填充日历的列标题，行标题或单元格。

import javax.swing.*;
import javax.swing.border.BevelBorder;
import java.awt.*;

public class GridPanel extends JPanel {

    private JLabel label;

    public GridPanel() {
        setupPanel();
    }

    public GridPanel(String text) {
        setupPanel();
        label = new JLabel(text);
        this.add(label);
    }

    public void setupPanel() {
        this.setBorder(new BevelBorder(BevelBorder.RAISED));
        this.setPreferredSize(new Dimension(100, 50));
    }

    public JPanel getGridPanel() {
        return this;
    }

}

日历和行标题的单元格添加到名为“CalendarPanel”的类中。

import javax.swing.*;
import java.awt.*;

public class CalendarPanel extends JPanel {

    private JPanel hoursPanel, rowHeaderPanel;

    private String[] hours = {"00:00", "01:00", "02:00", "03:00", "04:00", "05:00", "06:00", "07:00", "08:00", "09:00",
            "10:00", "11:00", "12:00", "13:00", "14:00", "15:00", "16:00", "17:00", "18:00", "19:00", "20:00", "21:00",
            "22:00", "23:00", };

    public CalendarPanel() {
        this.setLayout(new BorderLayout());

        hoursPanel = new JPanel(new GridLayout(24, 7));
        addHourPanels();

        this.add(hoursPanel, BorderLayout.CENTER);

        rowHeader();
    }

    public void addHourPanels() {
        for(int i = 0; i < 168; i++) {
            hoursPanel.add(new GridPanel());
        }
    }

    public void rowHeader() {
        rowHeaderPanel = new JPanel(new GridLayout(24, 1));
        for(int i = 0; i < hours.length; i++) {
            rowHeaderPanel.add(new GridPanel(hours[i]));
        }
        this.add(rowHeaderPanel, BorderLayout.WEST);
    }

}

最后，列标题会单独添加，因此无论用户是否向下滚动，它们都会保持可见状态。

import javax.swing.*;
import java.awt.*;

public class ColumnHeaderPanel extends JPanel {

    private String[] days = {"", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"};
    private GridPanel endPanel;

    public ColumnHeaderPanel() {
        this.setLayout(new GridLayout(1, 8));
        for(int i = 0; i < days.length; i++) {
            this.add(new GridPanel(days[i]));
        }
    }

}

主要课程：

import javax.swing.*;
import java.awt.*;

public class Main extends JFrame {

    private JScrollPane scrollPane;

    public Main() {
        super("Calendar");
        this.setSize(new Dimension(834, 591));
        this.setLayout(new BorderLayout());
        setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);

        CalendarPanel calendarPanel = new CalendarPanel();
//        this.add(calendarPanel);
        scrollPane = new JScrollPane(calendarPanel);
        this.add(scrollPane, BorderLayout.CENTER);
        this.add(new ColumnHeaderPanel(), BorderLayout.NORTH);

        setVisible(true);
    }

    public static void main(String args[]) {
        Main test = new Main();
    }

}

如初始图片所示，JScrollPane导致GridPanel上标记为“Sunday”的对齐问题。另外，我不得不在JFrame上使用setSize，就像用户调整窗口大小一样，所有面板对齐都搞砸了。解决这些问题的最佳方法是什么？
