But I want only May 09 2009


import java.awt.Component;
import java.util.Calendar;
import java.util.Date;

import javax.swing.AbstractCellEditor;
import javax.swing.JSpinner;
import javax.swing.JTable;
import javax.swing.SpinnerDateModel;
import javax.swing.SpinnerModel;
import javax.swing.table.TableCellEditor;

public class DateCellEditor extends AbstractCellEditor implements TableCellEditor
{
int selectedRow;
int selectedColumn;
JTable currentTable;
Date currentDate;
JSpinner spinner;

protected static final String EDIT = "edit";

public DateCellEditor()
{
Calendar calendar = Calendar.getInstance();
Date initDate = calendar.getTime();
System.out.println("INIT DATE++"+initDate);
calendar.add(Calendar.YEAR, -100);
Date earliestDate = calendar.getTime();
calendar.add(Calendar.YEAR, 200);
System.out.println("EARLIEST DATE++"+earliestDate);
Date latestDate = calendar.getTime();
System.out.println("LATEST DATE++"+latestDate);
SpinnerDateModel dateModel = new SpinnerDateModel(initDate,
earliestDate,
latestDate,
Calendar.YEAR);//ignored for user input
spinner = new JSpinner(dateModel);

spinner.setEditor(new JSpinner.DateEditor(spinner, "dd/MM/yyyy"));
}


public Component getTableCellEditorComponent(JTable table,
Object value, boolean isSelected, int row, int column) {
spinner.setValue(value);
currentTable = table;
selectedRow = row;
selectedColumn = column;
return spinner;
}

public Object getCellEditorValue() {
return spinner.getValue();
}


}


Please help me out

Thanks in advance

Ever heard of SimpleDateFormat?

db

[nehaa]

No I dont ever heard about SimpleDateFormat.

I'll definitely try this and will post if it fits my requirement so that can be helpful for others who face same difficulty.


THANKS FOR UR VALUABLE SUGGESTION AND TIME.

I have read about SimpleDateFormat.

If you please tell me how it can be applied with JSpinner in JTable column.

Thanks in advance.

[Darryl.Burke]

First tell me what exactly you mean by "i'm getting the format"

db

[nehaa]

FIRSTLY I WANT TO THANK YOU...THEN YOUR QUES FOR ME:
I'M GETTING DATE FORMAT IN GIVEN MANNER
"Sat May 09 10:12:00 IST 2009".
BUT I WANT TO DISPLAY DATE IN THIS FORMAT
"May 09 2009"..
HOPE THIS TIME I M MORE CLEAR.



NB

[Darryl.Burke]

No you're not. Repeating the same sentence in BLOCK CAPITALS is not a clarification, it's just rude.

Clarify "getting"

db

[nehaa]

I really was not rude..Neither was my intentions..If you felt so due to these BLOCK CAPITALS;then i m really sorry.My intentions were never to hurt anyone.

Though now I'll try this problem myself still to clarify:

I want that in one column of my JTable ,any user can select date which i am trying to provide using JSpinner .So I used the code i have given in my very first post.But with JSpinner(without SimpleDateFormat being used) date is displayed in this manner
" Sat May 09 10:12:00 IST 2009 "
that is combination of date and time.
but i want only date without time means
" May 09 2009 "..
In which i am facing some problem.

Hope now i am successful.

Thank you

Is your problem with your renderer or your editor? In other words, is the problem with the display of dates when the spinner is active, or is the problem present when you are using the spinner? If the problem is with the renderer, then the tutorials can show you how to use a date renderer. For instance:

import java.awt.Component;
import java.text.DateFormat;
import java.util.Calendar;
import java.util.Date;

import javax.swing.AbstractCellEditor;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JSpinner;
import javax.swing.JTable;
import javax.swing.SpinnerDateModel;
import javax.swing.SpinnerModel;
import javax.swing.table.DefaultTableCellRenderer;
import javax.swing.table.DefaultTableModel;
import javax.swing.table.TableCellEditor;

public class DateCellEditor extends AbstractCellEditor implements
    TableCellEditor
{
  int selectedRow;
  int selectedColumn;
  JTable currentTable;
  Date currentDate;
  JSpinner spinner;

  protected static final String EDIT = "edit";

  public DateCellEditor()
  {
    Calendar calendar = Calendar.getInstance();
    Date initDate = calendar.getTime();
    System.out.println("INIT DATE++" + initDate);
    calendar.add(Calendar.YEAR, -100);
    Date earliestDate = calendar.getTime();
    calendar.add(Calendar.YEAR, 200);
    System.out.println("EARLIEST DATE++" + earliestDate);
    Date latestDate = calendar.getTime();
    System.out.println("LATEST DATE++" + latestDate);
    SpinnerDateModel dateModel = new SpinnerDateModel(initDate, earliestDate,
        latestDate, Calendar.YEAR);// ignored for user input
    spinner = new JSpinner(dateModel);

    spinner.setEditor(new JSpinner.DateEditor(spinner, "dd/MM/yyyy"));
  }

  public Component getTableCellEditorComponent(JTable table, Object value,
      boolean isSelected, int row, int column)
  {
    spinner.setValue(value);
    currentTable = table;
    selectedRow = row;
    selectedColumn = column;
    return spinner;
  }

  public Object getCellEditorValue()
  {
    return spinner.getValue();
  }

  // from Sun tutorials: 
  //http://java.sun.com/docs/books/tutorial/uiswing/components/table.html#editrender  
  static class DateRenderer extends DefaultTableCellRenderer
  {
    DateFormat formatter;

    public DateRenderer()
    {
      super();
    }

    public void setValue(Object value)
    {
      if (formatter == null)
      {
        formatter = DateFormat.getDateInstance();
      }
      setText((value == null) ? "" : formatter.format(value));
    }
  }

  

  private static void createAndShowUI()
  {
    Date[][] dates =
    {
        {new Date(Calendar.getInstance().getTimeInMillis())}
    };
    String[] titles =
    {
      "Date"
    };
    JTable table = new JTable(dates, titles);
    table.setDefaultRenderer(Object.class, new DateRenderer());
    table.setDefaultEditor(Object.class, new DateCellEditor());
    
    JFrame frame = new JFrame("DateCellEditor");
    frame.getContentPane().add(new JScrollPane(table));
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.pack();
    frame.setLocationRelativeTo(null);
    frame.setVisible(true);
  }

  public static void main(String[] args)
  {
    java.awt.EventQueue.invokeLater(new Runnable()
    {
      public void run()
      {
        createAndShowUI();
      }
    });
  }

}
