Thread: library or component for Hijra date chooser

i think you talk about this part of code

numBtn.addActionListener(new ActionListener() {
                        public void actionPerformed(ActionEvent event) {
                            JButton source = (JButton) event.getSource();
                            if (source.getText().length() == 0) {
 
                                numBtn.setForeground(dateFontColor);
 
                                return;
                            }
                            dayColorUpdate(true);
                            numBtn.setBackground(palletTableColor);
                            numBtn.setForeground(dateFontColor);
                            source.setForeground(todayBackColor);

Here it is specified which button the user has clicked on

in the original code for Gregory date picker before we edit and convert to hijra this code and colors work Properly

I did not touch that part of the code and did not edit it. There was the same problem in Hijri

--- Update ---

in 2 code just this part is changed

 
                            da = newDay;
 
                            setDate();

and in original

Calendar cal = getCalendar();
                            cal.set(Calendar.DAY_OF_MONTH, newDay);
                            setDate(cal.getTime());

Do you think I would ask a question if my code was correct? I even sent you a picture of my code problem

this is all my code now

I did not notice in the original class Calendar.DAY_OF_WEEK What does it do?
That is why I do not know how much of the Hijri calendar I should devote to it

The getValue() method of java.time.DayOfWeek is an in-built function in Java which return the integer value assigned to the 7 days of the week, i.e, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday and Sunday
but When I set this value as well, the color shapes still do not work

private void dayColorUpdate(boolean isOldDay) {
 
            ye = (Integer) yearSpin.getValue();
            mo = (Integer) monthSpin.getValue();
            System.out.println("spinner ye " + ye);
            System.out.println("spinner mo " + mo);
            Locale ar = new Locale("ar");
            DateTimeFormatter dayOfMoonNum = DateTimeFormatter.ofPattern("d", ar);
            DateTimeFormatter weekNumOfMonth = DateTimeFormatter.ofPattern("e", ar);
 
            HijrahDate hijrahDate = HijrahChronology.INSTANCE.date(ye, mo, da);
            String MoondayNum = hijrahDate.format(dayOfMoonNum);
            String dayofweek = hijrahDate.format(weekNumOfMonth);
            System.out.println("localized day-of-week= "+dayofweek);
            int daysofweek = Integer.parseInt(dayofweek);
            int moondayNumb = Integer.parseInt(MoondayNum);
            int moondaysnumber = hijrahDate.lengthOfMonth();
            System.out.println("hijrahDate= " + hijrahDate);
            System.out.println("Number day-of-month   " + MoondayNum);
 
            System.out.println("Number of days of the month   " + moondaysnumber);
            System.out.println("The day it was last clicked= "+moondayNumb);
            int actionCommandId = moondayNumb + 3 + daysofweek;
 
            int i = actionCommandId / 7;
            System.out.println("i= "+i);
            int j = actionCommandId % 7;
            System.out.println("i= "+i);
            if (isOldDay) {
                daysButton[i][j].setForeground(dateFontColor);

Why is the output of the buttons in my code different from the original code?
in the my code when i click on buten text
numBtn.getText();10spinner ye 1442
in the original code
numBtn.getText();10i= 1

--- Update ---

I'm totally confused I do not know where to start now and what to do

Select a date: For example 1442/09/17
then write down the row, column for that date: third row and sixth column --> it is Fourth row and sixth column
There is a first row, but we have hidden buttons

--- Update ---

i now add print in createWeekAndDayPanal() after

 return;
                            }

System.out.println("numBtn.getText();" + numBtn.getText());

I'm totally confused I do not know where to start now and what to do

--- Update ---

Since I'm working on unresolved code with trial and error, I backed up, and another reason I always post code here is because you know what I did and a backup of Stay here

90% is work now but now show 2 day's get orange
replace with this

 private void dayColorUpdate(boolean isOldDay) {
 
            String s = String.valueOf(da);
 
            for (int a = 0; a < 6; a++) {
                for (int b = 0; b < 7; b++) {
                    daysButton[a][b].setForeground(dateFontColor);
                    daysButton[a][6].setForeground(weekendFontColor);
                    if (daysButton[a][b].getText().equals(s)) {
                        daysButton[a][b].setForeground(todayBackColor);
                    }
                }
            }
        }

i don't know now what is problem

--- Update ---

The baton that was orange and the baton that I just clicked and the same cycle continues, the last 2 batons always turn orange

--- Update ---

I do not understand where the logic of this code is wrong

this part is for weekend turn red
daysButton[a][6].setForeground(weekendFontColor);

--- Update ---

The baton that was orange and the baton that I just clicked and the same cycle continues, the last 2 batons always turn orange

I do not understand where the logic of this code is wrong
