Thread: library or component for Hijra date chooser

You do not understand what I mean
I mean, when the size of the extends JPanel changes, the datePanels remain the old size And it does not get bigger or smaller That's why the size of the text box does not get bigger It does not matter if this problem is not solved


--- Update ---


But now the user can not set date in text Hijri from the new from
For example, by clicking on the new button on new form update date in the hiji text

in original date chooser use gregorian date and for set date in new form we use gregorian1.setDate(new Date());
this is original date chooser

in hijri date when i use hijri.setDate(new Date());
add to Hijrah class this code but i don't know how i must editn it for work and set date in jtext

        throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
    }

this is hijri date class

--- Update ---

Must add a new value to ye mo da
after thar run testMethod() and datetext.setText(testMethod());

user must write like this like Gregorian. in Gregorian user use this method for Gregorian

String sDate1="1402/09/20";  
    Date date1=new SimpleDateFormat("yyyy/MM/dd").parse(sDate1);  
    hijri1.setDate(date1);
   gregorian1.setDate(date1);

then i think Must add a new value to ye mo da
after thar run testMethod() and datetext.setText(testMethod());

--- Update ---

now i see a new bug
when system date change after 12 Am The value of days of the month that are stored in the buttons is not considered on the day , for example, 1402/09/20 is transferred to Wednesday instead of Sunday.

i change them like this

 private HijrahDate getCalendar() {
 
            HijrahDate today = HijrahChronology.INSTANCE.date(ye, mo, da);
 
            return today;
        }

and

public void stateChanged(ChangeEvent e) {
            dayColorUpdate(true);
            JSpinner source = (JSpinner) e.getSource();
            if (source.getName().equals("Year")) {
                ye = (getSelectedYear());
            } else {
                mo = (getSelectedMonth());
            }
            getCalendar();
            reflushWeekAndDay();
            setDate();
            mothnam();
        }

but not fix when i change system date but The number of days of the month stored in the buttons on the desired day is not considered
Could there be a problem with this part of code ?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30
The sixth month

Seventh month
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30
The eighth month
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 (29)

Tenth month
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 (30)

and in java To find out if a month has thirty days or twenty-nine days, we use the following command

HijrahDate date = HijrahChronology.INSTANCE.date(1402,9, 10);
System.out.println(date.lengthOfMonth());

or this code

HijrahDate hijrahDate = HijrahChronology.INSTANCE.date(1442, 09, 10);
 int moondaysnumber = hijrahDate.lengthOfMonth();
            System.out.println("int MonthdayNum "+moondaysnumber);

but i don't know how i must fix this bug

when i fix today date hijridate get in own place like "1442/09/20" Displays Sunday and change system date to 2021-05-03 hijridate show "1442/09/20" Monday
And if another day goes by the system calendar like 2021-05-04 hijridate show "1442/09/20" Tuesday
Every day that goes back the system calendar goes back one day hijridate Every day that goes by, the system calendar goes by one day hijridate From your place in the batons For example, if it is in Baton [1][6], it goes to Baton[1][7] on the 20 Day of the month 9 or Baton [1][5], it goes to Baton[1][6] on the 20 Day of the month 9

The problem is that until the system date is not changed, the code works perfectly. I do not understand why changing the system date causes all these problems when all the functions follow the Hijri date.

Even when using spinners, the number of days is in the right place
