How to show arabic and arabic in a JTextBox when user enter the numbers?

[raminaa niilian]

Hi
Thank you for reading my post.
I am looking for a way to show Arabic digits in the JTextBox when user is entering the digitst instead of showing Europian digits. User keyboard layout is Arabic but numbers are shown in euopian instead of arabic.

Thanks.

Hi Raminaa,

I have never done this, but I would suggest taking a look at the following link:

http://www.java2s.com/Code/Java/I18N/FormattingMessagesArabicDigit.htm

and then adding a KeyListener to your TextBox. In the listener, whenever the user presses a numeric key you can convert the text by using the above code. It won't be the most efficient way, but it should work fine for small amount of data.

Cheers.

I'd use a DocumentFilter instead of a KeyListener, so you can replace numbers in text pasted into the text box as well:

DocumentFilter filter = new DocumentFilter()
{
    public void insertString(DocumentFilter.FilterBypass fb, int offset, String string, AttributeSet attr) throws BadLocationException
    {
        // modify string
        super.insertString(fb, offset, string, attr);
    }

    public void replace(DocumentFilter.FilterBypass fb, int offset, int length, String text, AttributeSet attrs) throws BadLocationException
    {
        // modify string
        super.replace(fb, offset, length, string, attrs);
    }
};
AbstractDocument doc = (AbstractDocument)textField.getDocument();
doc.setDocumentFilter(filter);
