Hi,

I have a java swing app with some data entry screens. In one of the screens I need to choose the date from date picker.I have separate java class for java date picker.But I need to open the date picker as Popup window and selecting the any of the date I need to close the popup and selected date should set into a textfield in parent window.

I dont have idea on

1.Opening a date picker java file as popup window
2.Returning a selected date to parent window.

please help me on this..

here is the code for DatePickerSimple.java which needs to be opened as popup window
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
class DatePickerSimple extends JFrame
{
JButton[] btn = new JButton[49];
int month = java.util.Calendar.getInstance().get(java.util.Calendar.MONTH);
int year = java.util.Calendar.getInstance().get(java.util.Calendar.YEAR);;
JLabel lbl = new JLabel("",JLabel.CENTER);

public DatePickerSimple()
{
buildGUI();
setDates();
}
public void buildGUI()
{
setLocation(300,300);
setDefaultCloseOperation(EXIT_ON_CLOSE);
String[] header = {"Sun","Mon","Tue","Wed","Thur","Fri","Sat"};
JPanel midPanel = new JPanel(new GridLayout(7,7));
//midPanel.setPreferredSize(new Dimension(200,200));
for(int x = 0; x < btn.length; x++)
{
final int selection = x;
btn[x] = new JButton();
btn[x].setFocusPainted(false);
if(x>6)btn[x].addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent ae){
displayDatePicked(btn[selection].getActionCommand());}});
if(x < 7){btn[x].setFont(new Font("Lucida",Font.PLAIN,10)); btn[x].setText(header[x]);}
midPanel.add(btn[x]);
}
JPanel lowPanel = new JPanel(new GridLayout(1,3));
JButton prevBtn = new JButton("<< Previous");
prevBtn.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent ae){
month--;setDates();}});
lowPanel.add(prevBtn);
lowPanel.add(lbl);
JButton nextBtn = new JButton("Next >>");
nextBtn.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent ae){
month++;setDates();}});
lowPanel.add(nextBtn);
getContentPane().add(midPanel,BorderLayout.CENTER);
getContentPane().add(lowPanel,BorderLayout.SOUTH);
pack();
}
public void setDates()
{
for(int x = 7; x < btn.length; x++) btn[x].setText("");
java.text.SimpleDateFormat sdf = new java.text.SimpleDateFormat("MMMM yyyy");
java.util.Calendar cal = java.util.Calendar.getInstance();
cal.set(year,month,1);
int dayOfWeek = cal.get(java.util.Calendar.DAY_OF_WEEK);
int daysInMonth = cal.getActualMaximum(java.util.Calendar.DAY_OF_MONTH);
for(int x = 6+dayOfWeek,day = 1; day <= daysInMonth; x++,day++) btn[x].setText(""+day);
lbl.setText(sdf.format(cal.getTime()));
setTitle("Date Picker - "+lbl.getText());
}
public void displayDatePicked(String day)
{
if(day.equals("") == false)
{
java.text.SimpleDateFormat sdf = new java.text.SimpleDateFormat("EEEE d MMMM, yyyy");
java.util.Calendar cal = java.util.Calendar.getInstance();
cal.set(year,month,Integer.parseInt(day));
JOptionPane.showMessageDialog(this,"You picked "+sdf.format(cal.getTime()));

}
}

public static void main(String[] args){
new DatePickerSimple().setVisible(true);
}
}

Please edit your post to UseCodeTags. It's unnecessarily hard to read the code as it is, making it less likely that people will bother to do so.
