　　一次项目研发中需要日期时间选择控件，网上提供的不多，且质量一般，所以只好自己做，参考了网上某位同学的作品Jave日期选择控件DateChooser 。

目前的代码将日期时间选择封装在一个按钮组件内，应该很好用，支持Application 、Applet


CODE:

import java.util.Date.
import java.util.Calendar.
import java.text.DateFormat.

import java.awt.Frame .

import java.awt.event.ActionEvent.
import java.awt.event.ActionListener.

public class DateChooserJButton extends JButton {


private DateChooser dateChooser =null.

private String preLabel ="" .


public DateChooserJButton() {
this(getNowDate()) .
}


public DateChooserJButton(SimpleDateFormat df , String dateString) {
this() .
setText(df,dateString) .
}


public DateChooserJButton(Date date) {
this("",date).
}

public DateChooserJButton(String preLabel , Date date) {
if (preLabel!=null) this.preLabel = preLabel .
setDate(date) .
setBorder(null) .
setCursor(new Cursor(Cursor.HAND_CURSOR)) .
super.addActionListener( new ActionListener() {
public void actionPerformed(ActionEvent e) {
if (dateChooser==null) dateChooser = new DateChooser().
Point p = getLocationOnScreen() .
p.y = p.y 30 .
dateChooser.showDateChooser(p) .
}
}) .
}


private static Date getNowDate() {
return Calendar.getInstance().getTime() .
}

private static SimpleDateFormat getDefaultDateFormat() {
return new SimpleDateFormat("yyyy年MM月dd日HH时") .
