我正在使用最新版本的JDatePicker 1.3.4。应该如何实现?
我收到一个编译器错误:构造函数JDatePanelImpl(UtilDateModel)未定义。建议的解决方法是:添加参数以匹配JDatePanelImpl(DateModel,Properties)。应该将什么作为属性参数传入?

class date2 {
void GUI() {
JFrame f1 = new JFrame();
f1.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f1.setSize(300, 300);
f1.setVisible(true);
Container conn = f1.getContentPane();
conn.setLayout(null);
UtilDateModel model = new UtilDateModel();
//model.setDate(20,04,2014);
JDatePanelImpl datePanel = new JDatePanelImpl(model);
JDatePickerImpl datePicker = new JDatePickerImpl(datePanel);
f1.add(datePicker);
}
}
运行者
class testDate2 {
public void main(String[] args) {
date2 d1 = new date2();
d1.GUI();
}
}
最佳答案
假设您使用的是1.3.4,则构造函数要求已更改...
UtilDateModel model = new UtilDateModel();
//model.setDate(20,04,2014);
// Need this...
Properties p = new Properties();
p.put("text.today", "Today");
p.put("text.month", "Month");
p.put("text.year", "Year");
JDatePanelImpl datePanel = new JDatePanelImpl(model, p);
// Don't know about the formatter, but there it is...
JDatePickerImpl datePicker = new JDatePickerImpl(datePanel, new DateLabelFormatter());
使用此
AbstractFormatter
...public class DateLabelFormatter extends AbstractFormatter {
private String datePattern = "yyyy-MM-dd";
private SimpleDateFormat dateFormatter = new SimpleDateFormat(datePattern);
@Override
public Object stringToValue(String text) throws ParseException {
return dateFormatter.parseObject(text);
}
@Override
public String valueToString(Object value) throws ParseException {
if (value != null) {
Calendar cal = (Calendar) value;
return dateFormatter.format(cal.getTime());
}
return "";
}
}
