java日期时间选择控件(代码)

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.text.SimpleDateFormat;import java.text.ParseException ;import java.awt.Color ;import java.awt.Font;import java.awt.Point ;import java.awt.Dimension ;import java.awt.BorderLayout ;import java.awt.FlowLayout ;import java.awt.GridLayout ;import java.awt.Component ;import java.awt.Cursor ;import java.awt.Frame ;

import java.awt.event.ActionEvent;import java.awt.event.ActionListener;import java.awt.event.MouseListener;import java.awt.event.MouseAdapter;import java.awt.event.MouseEvent;//import javax.swing.JFrame;import javax.swing.JButton;import javax.swing.JDialog;import javax.swing.JPanel;import javax.swing.JLabel;import javax.swing.JSpinner ;import javax.swing.JSpinner.NumberEditor ;import javax.swing.SpinnerNumberModel;import javax.swing.SwingUtilities;import javax.swing.SwingConstants ;import javax.swing.event.ChangeListener ;import javax.swing.event.ChangeEvent ;import javax.swing.border.LineBorder ;

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") ;}

java日期时间选择控件(代码)(2)

public void setText(SimpleDateFormat df , String s) {Date date ;try {date = df.parse(s) ;}catch (ParseException e) {date = getNowDate() ;}setDate(date) ;}

public void setDate(Date date) {super.setText(preLabel+getDefaultDateFormat().format(date));}

public Date getDate() {String dateString = getText().substring(preLabel.length());try {return getDefaultDateFormat().parse(dateString); } catch (ParseException e) {return getNowDate() ;}

}

//覆盖父类的方法使之无效public void addActionListener(ActionListener listener ) {}
