Thread: library or component for Hijra date chooser

choosdate is button don't need variable and value for click and load jdialog
datetext variable is ye mo da and this variable fill from here

public void hdate() {
        HijrahDate hijrahDate = HijrahDate.now();
        DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy/MM/dd");
        String formatted = formatter.format(hijrahDate); // 07/03/1439 
        ye = Integer.parseInt(formatted.substring(0, 4));
        mo = Integer.parseInt(formatted.substring(5, 7));
        da = Integer.parseInt(formatted.substring(8, 10));
    }

and i call it here top of load class

 public Hijrah() {
        hdate();// load ye mo da for variable's
        choosdate.setText("choos date");
        add(datePanels);
        datePanels.setPreferredSize(new Dimension(640, 480));
        datePanels.setLayout(new FlowLayout());
 
        try {
            img = ImageIO.read(getClass().getResource("cleander.png"));
            choosdate.setIcon(new ImageIcon(img));
        } catch (IOException ex) {
        }
 
        setDate();
//        datetext.setEditable(false);
        setCursor(new Cursor(Cursor.HAND_CURSOR));
        addListeners();
        datePanels.add(choosdate);
        datePanels.add(datetext);
    }

Which variables do you mean? if you mean ye mo da it get value from hdate() when form loaded else you say Which variables do you mean?

i don't know how you get that eror choosdate is private JButton choosdate; and just called choosdate.setText("choos date"); for set label for it and added to datePanels datePanels.add(choosdate); And you have no other use for this baton. it is made to be displayed in front of the JText

--- Update ---

my code only 471 line i can't unrestand how your's is 481 line

i use this class

    // set month when click on jdialog button's and spinner and textfild
    public void mothnam() {
        monthNameLabel.setText(moonNames[mo - 1]);
    }
 
    //set date for jtext and jdialog....
    String testMethod() {                  //  ADDED

        HijrahDate today = HijrahChronology.INSTANCE.date(ye, mo, da);
        String formatted = formatter.format(today); // 07/03/1439
 
        return formatted.toString(); //<<<<<< ADDED
    }
}

and cleaned Bild for create component
after that use component for add date to my form
and this my all code in form

--- Update ---

Here is a picture of my program output
https://s19.picofile.com/file/8432397718/Capture.JPG

if you think soft problem change to this

 int ye;
    int mo;
    int ;

 
 int ye=1442;
    int mo=9;
    int da=21;

--- Update ---

i think all problem started when i change

public class Hijrah extends JTextField {

public class Hijrah extends JPanel {

this is before extend to jpanel

test this and see problem is soft or nost

ok now how we can change extend to jpanel That we do not face a problem

pleas edit extend text to panel and add button for me to i can see what happened and learn it

--- Update ---

Unfortunately, I learn the code better and faster to explain it, so I use project-based tutorials.

i think now all it's fixed

    }
}

last problem how i must set jtext and jbutton in panel if resized panel jtext size change?

--- Update ---

i use this

javax.swing.GroupLayout datePanelsLayout = new javax.swing.GroupLayout(datePanels);
        datePanels.setLayout(datePanelsLayout);
        datePanelsLayout.setHorizontalGroup(
            datePanelsLayout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
            .addGroup(datePanelsLayout.createSequentialGroup()
                .addComponent(datetext, javax.swing.GroupLayout.PREFERRED_SIZE, 126, javax.swing.GroupLayout.PREFERRED_SIZE)
                .addGap(0, 0, 0)
                .addComponent(choosdate, javax.swing.GroupLayout.PREFERRED_SIZE, 22, javax.swing.GroupLayout.PREFERRED_SIZE)
                .addGap(0, 0, Short.MAX_VALUE))
        );
        datePanelsLayout.setVerticalGroup(
            datePanelsLayout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
            .addGroup(datePanelsLayout.createSequentialGroup()
                .addGroup(datePanelsLayout.createParallelGroup(javax.swing.GroupLayout.Alignment.BASELINE)
                    .addComponent(datetext, javax.swing.GroupLayout.PREFERRED_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.PREFERRED_SIZE)
                    .addComponent(choosdate, javax.swing.GroupLayout.PREFERRED_SIZE, 20, javax.swing.GroupLayout.PREFERRED_SIZE))
                .addGap(0, 0, Short.MAX_VALUE))
        );

but i don't know how fix datePanels to extends JPanel

--- Update ---
