Thread: library or component for Hijra date chooser

Look at how NewClass worked. When the year spinner was clicked, the value shown in the textfield was immediately updated.
The new code prints out a message but does not update the text field.

I do not understand exactly what this part of the code does

Print this before and after the call to that method: cal.getTime()
The first will be some date, the second will be for the 1st day of the month

--- Update ---

how to run this part before anything else

Run it in the constructor.

--- Update ---

This method should use an array:

 public void mothnam() {
        if (mo == 1) {
            monthNameLabel.setText("ٱلْمُحَرَّم‎");
....
       monthNameLabel.setText(monthNames[mo]);    // get name from monthNames arrray

this part dont work after mo ==11 in mo==12 show this error
monthNameLabel.setText(monthNames[mo]);

Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: 12

--- Update ---

must be use like this monthNameLabel.setText(monthNames[mo-1]);

Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: 12

If the array has 12 items then the valid indexes into the array are 0 to 11. If you want to use 1 to 12 as the indexes, then either subtract 1 to get 0 to 11 or add an empty value are the front of the array so there are elements at indexes 1 to 12.

how to run this part before anything else hdate()

Are you saying that the hdate() method needs to be run before anything else?
Add a call to hdate() in the class's constructor.

Call it just like the code calls the addListeners() method.


What is in the Date object passed to the constructor? What is it used for?

now i have just 2 problem and finish
first i ask important question
In the second and eleventh month date start from the second day
The program starts filling in the values from the first row. and in these 2 months starts from the zero row .
Please pay attention to the photo

--- Update ---

It is very interesting to me that there is no component for selecting the day for Hijri. I wonder if there is no Java programmer in the Arabs?

In the second and eleventh month date start from the second day
The program starts filling in the values from the first row. and in these 2 months starts from the zero row .

How are you trying to debug the code to see what happens? Add some print statements that print out the values of the variables that are used in the code that fills in the month days so you can see what is happening.
What value should dayNo have for the day of 1 to be in the last column?


Why is there a Date object passed to the constructor and to the setDate method?
Its value is never used. It should be removed.

when i remove setDate(date); i see this errors

What did you remove? I suggested removing the Date object. So the call to setDate would be:

   setDate();  // without Date object

And also remove the Date from the constructor:

 
    public Hijrah5(String dateFormatPattern) {
        this();
        DEFAULT_DATE_FORMAT = dateFormatPattern;
    }
 
    public Hijrah5() {
        hdate();
        setDate();
        setEditable(false);
        setCursor(new Cursor(Cursor.HAND_CURSOR));
        addListeners();
    }

Is the problem that the row with a 1 at the end is not shown?
And the the first number on the first row is a 2?

What value needs to be in dayNo for the 1 to be placed in the correct column on the first row?

method setDate in class Hijrah cannot be applied to given types;

Remove the Date object from the setDate method. The Date object is not used.

What value needs to be in dayNo for the 1 to be placed in the correct column on the first row? i don't know

Study the code to see how the value in dayNo is used to determine what column the 1 is placed in and how the 2 goes in the next column, etc

i think i must edit this part of code for days but i don't know how

Before you edit any code, you need to understand what the desired results are. What does the code need to do?
How can the code be modified to do it?

You need to do this:
Study the code to see how the value in dayNo is used to determine what column the 1 is placed in and how the 2 goes in the next column, etc

Use a paper an pencil with 7 columns to determine the value of dayNo for the 1 to go in each column. Look at the debug print outs the code makes now to see what the dayNo value is for each placement of the 1 on the first row.

int dayNo = 4 - WeekdayNumb;
That is, on which day of the week we are on, 4 days are reduced and the remaining 3 days are the number of days of the day, so that each number is displayed on its own day.
But when I lower it, the values are still not in place

What value needs to be in dayNo for the 1 to be placed in the last column?
Look at the code to see how dayNo is used.

You keep skipping answering this question. I'll repeat it:
What value needs to be in dayNo for the 1 to be placed in the last column?

If dayNo is 1 what column will have the 1?
Add a test line of code that sets the value of dayNo then run the code and see what column the 1 is in.
For example:

            int dayNo = 3 - WeekdayNumb;
            dayNo = 1;   //*** Testing what column will 1 be in ???

Then change the 1 to a 0 and see what happens.

there are only 2 problems left

Only work on one problem at a time. Currently want the 1 to be in the correct column.

when dayNo =0 start day is empty

That is strange. For me when I set dayNo to 0, the 1 in placed in the second column.
Do you mean that the first column is blank and the 1 is in the second column?
Isn't that what is needed if the first day of the month is on the second day of the week?
What if the first day of the month is on the last day of the week? What value does dayNo need to put the 1 in the last column?
