Thread: library or component for Hijra date chooser

I searched a lot but in the end I did not understand where to put listener(); to close dateDialog and i test and put in the all block of my code one by one and i just see errors and or never open dateDialog and just i see in output print

dateDialog : Focus Gained
dateDialog : Focus Lost

OR

Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException

can we use WindowListener for dateDialog Focus Lost???

Does the JDialog need to be modal? Change it to non-modal and see if it works as desired.

Did you change the JDialog to be non-modal? That is done in the constructor.

What happens when that is done?

Why do you have small methods that call other small methods?
Why not do the work in the first method instead of calling the second method?

        JDialog dialog = new JDialog(owner, "Date Selected", true);

Read the API doc for the JDialog class and see what the 3 arguments that are passed to it are for.
Change the arguments so that the JDialog is not modal.

where i must use this

Replace the constructor that is already in the class with that new version.

i use this

private JDialog createDateDialog(Frame owner, JPanel contentPanel) {
        JDialog dialog = new JDialog(owner, "Date Selected", false);// Non-modal
//        JDialog dialog = new JDialog(owner, "Date Selected", true);
        dialog.setUndecorated(true);
        dialog.getContentPane().add(contentPanel, BorderLayout.CENTER);
        dialog.pack();
        dialog.setSize(DIALOG_WIDTH, DIALOG_HEIGHT);
listener();
        return dialog;
 
    }

i see this
https://www.w3schools.com/java/java_constructors.asp
and use this

public Hijrah() {
        this(new Date());
        listener();
    }

but not working

What component(s) are the listeners being added to? There are at least 3 components in the GUI: the window, the textfield and the dialog box.
For which component do you want to detect focus changes?

not working

for dialog box

Is that where the add listener is called for?

no it is not because i called before and not working

private JDialog createDateDialog(Frame owner, JPanel contentPanel) {
        JDialog dialog = new JDialog(owner, "Date Selected", false);// Non-modal
//        JDialog dialog = new JDialog(owner, "Date Selected", true);
        dialog.setUndecorated(true);
        dialog.getContentPane().add(contentPanel, BorderLayout.CENTER);
        dialog.pack();
        dialog.setSize(DIALOG_WIDTH, DIALOG_HEIGHT);
      listener();
        return dialog;
 
    }

i add for window, the textfield and again not working

not working

How does the listener() method add the focus listener to the JDialog object? How does the listener() method get access to the dialog object?
There needs to be a call to the dialog's addFocusListener method.

For what object is this method called

      addFocusListener(new FocusAdapter() {

Since it doesn't have a specific object reference with it, then it is calling the method for the class that the listener() method is in.

Look at these statements:

        dialog.setUndecorated(true);
        dialog.getContentPane().add(contentPanel, BorderLayout.CENTER);
        dialog.pack();
        dialog.setSize(DIALOG_WIDTH, DIALOG_HEIGHT);

They all call methods for the dialog object.

That is what the add listener needs:

   dialog.addFocusListener(new FocusAdapter() {

Get rid of the listener() method. Move its code to where it is needed.

What actions do you take with the program?
What is printed when the program executes?

Please post all of the new code.

Look at this site: https://stackoverflow.com/questions/...ide-of-jdialog
That code shows what listener to use in its code example. Try using that one.

addFocusListener in in stackoverflow user addWindowFocusListener but how i must replace it in my code?

Yes. Replace add... with addWindow... as shown in the link.

i fixed whit this

JDialog dialog = new JDialog(owner, "Date Selected", false);// Non-modal
//        JDialog dialog = new JDialog(owner, "Date Selected", true);
        dialog.setUndecorated(true);
        dialog.getContentPane().add(contentPanel, BorderLayout.CENTER);
        dialog.pack();
        dialog.setSize(DIALOG_WIDTH, DIALOG_HEIGHT);
 
        dialog.addWindowFocusListener(new WindowFocusListener() {
            public void windowLostFocus(WindowEvent e) {
                dialog.setVisible(false);
            }
 
            public void windowGainedFocus(WindowEvent e) {
            }
        });

--- Update ---

now how i must say start day started from Saturday in dialog box?? this is my all code
