Thread: library or component for Hijra date chooser

now how i can say when user click on JSpinner moon or year jdialog buttons update? and when user click on buttons text field update?

i fix this part like this

 String[] moonNames = {"Moharram", "Safar", "Rabi'al avval", "Rabi'al Sani", "Jmadi'al avval", "Jamadi'al Sani", "Rajab", "Shaban", "Ramadan", "Shavval", "Zolgha'de", "Zol'Hajje"};
            JLabel monthNameLabel = new JLabel(moonNames[(Integer) monthSpin.getValue()-1]);  // get name from array
            panel.add(monthNameLabel);

now how i must use spinner for change jbox values when i change moon spinner or year sppiner?

i think this part must be change but i don't know how

public void stateChanged(ChangeEvent e) {
            dayColorUpdate(true);
 
            JSpinner source = (JSpinner) e.getSource();
            Calendar cal = getCalendar();
            if (source.getName().equals("Year")) {
                cal.set(Calendar.YEAR, getSelectedYear());
            } else {
                cal.set(Calendar.MONTH, getSelectedMonth() - 1);
            }
            setDate(cal.getTime());
            reflushWeekAndDay();
        }

I'm for call hijri date use this method

HijrahDate hijrahDate = HijrahDate.now();
System.out.println("hijrahDate   " + hijrahDate);

but i don't know how i must set YEAR or MONTH for it
and with this i can find moon number and year number

Locale ar = new Locale("ar");
            DateTimeFormatter YearNum = DateTimeFormatter.ofPattern("u", ar);
            DateTimeFormatter dayOfMoonNum = DateTimeFormatter.ofPattern("M", ar);
            HijrahDate hijrahDate = HijrahDate.now();
            String HijriYearNum = hijrahDate.format(YearNum);
            System.out.println("YearNum   " + HijriYearNum);
            String MoonOfYear = hijrahDate.format(dayOfMoonNum);
            System.out.println("month-of-year   " + MoonOfYear);

i use like that but jbox not updates

 public void stateChanged(ChangeEvent e) {
            dayColorUpdate(true);
 
            JSpinner source = (JSpinner) e.getSource();
            Locale ar = new Locale("ar");
            DateTimeFormatter YearNum = DateTimeFormatter.ofPattern("u", ar);
            DateTimeFormatter numOfMoonNum = DateTimeFormatter.ofPattern("M", ar);
            DateTimeFormatter dayOfMoonNum = DateTimeFormatter.ofPattern("d", ar);
            HijrahDate hijrahDate = HijrahDate.now();
            HijrahChronology crono = hijrahDate.getChronology();
            String HijriYearNum = hijrahDate.format(YearNum);
            System.out.println("YearNum   " + HijriYearNum);
            String MoonOfYear = hijrahDate.format(numOfMoonNum);
            System.out.println("month-of-year   " + MoonOfYear);
            System.out.println("crono   " + crono);
            String dayOfMoonNums = hijrahDate.format(dayOfMoonNum);
            int moondayNumb = Integer.parseInt(dayOfMoonNums);
            System.out.println("crono   " + crono);
            HijrahDate date;
            int HijriMoonOfYearb = Integer.parseInt(MoonOfYear);
 
            if (source.getName().equals("Year")) {
 
                date = crono.date(getSelectedYear(), HijriMoonOfYearb, moondayNumb);               
                hijrahDate=date;
                System.out.println("date Year  " + date);
            } else {
                date = crono.date(getSelectedYear(), getSelectedMonth(), moondayNumb);
                hijrahDate=date;
                System.out.println("date MONTH  " + date);
            }
               hijrahDate=date;
                reflushWeekAndDay();
        }

in system pint show correctly but jdialog not updated it is all my code now when jsppiner for year or moonth change jdialog not update and when jsppiner moonth change moonNames not updatet

I think it's here but I do not know how to do it

private JPanel createWeekAndDayPanal() {
//            String colname[] = {"بس", "اح", "ثن", "ثل", "ار", "خم", "جم"};
            String colname[] = {"Sa", "sun", "Mon", "Tu", "We", "Th", "Fr"};
            JPanel panel = new JPanel();
            panel.setFont(new Font("Arial", Font.PLAIN, 10));
            panel.setLayout(new GridLayout(7, 7));
            panel.setBackground(Color.white);
 
            for (int i = 0; i < 7; i++) {
                JLabel cell = new JLabel(colname[i]);
                cell.setHorizontalAlignment(JLabel.CENTER);
//                if (i == 0 || i == 6) {
                if (i == 6) {
                    cell.setForeground(weekendFontColor);
                } else {
                    cell.setForeground(weekFontColor);
                }
                panel.add(cell);
            }
 
            int actionCommandId = 0;
            for (int i = 0; i < 6; i++) {
                for (int j = 0; j < 7; j++) {
                    JButton numBtn = new JButton();
                    numBtn.setBorder(null);
                    numBtn.setHorizontalAlignment(SwingConstants.CENTER);
                    numBtn.setActionCommand(String.valueOf(actionCommandId));
                    numBtn.setBackground(palletTableColor);
                    numBtn.setForeground(dateFontColor);
                    numBtn.addActionListener(new ActionListener() {
                        public void actionPerformed(ActionEvent event) {
                            JButton source = (JButton) event.getSource();
                            if (source.getText().length() == 0) {
                                return;
                            }
                            dayColorUpdate(true);
                            source.setForeground(todayBackColor);
                            int newDay = Integer.parseInt(source.getText());
                            Calendar cal = getCalendar();
                            cal.set(Calendar.DAY_OF_MONTH, newDay);
                            setDate(cal.getTime());
//hijrahDate=date
                            dateDialog.setVisible(false);
                        }
                    });
                    if (j == 6) {
                        numBtn.setForeground(weekendFontColor);
                    } else {
                        numBtn.setForeground(dateFontColor);
                    }
                    daysButton[i][j] = numBtn;
                    panel.add(numBtn);
                    actionCommandId++;
                }
            }
 
            return panel;
        }

Because in this part is not used in the Hijri calendar

setDate(cal.getTime());

My brain is no longer working. I no longer know what to do

i need after change jspinner year or month jbox is updated
yes i wanted the user's interactions with the dialog window to set year, month or day of the date and then have that selected date display in the textfield But after clicking on the day in the box.
