How do I implement JDatePicker
提问by Ashane Alvis
I am working with the latest release 1.3.4 of JDatePicker. How should it be implemented?
我正在使用 JDatePicker 的最新版本 1.3.4。应该如何实施？
I get a compiler error: The constructor JDatePanelImpl(UtilDateModel) is undefined. The suggested fix is to: add argument to match JDatePanelImpl(DateModel, Properties). What should be passed in as the properties argument?
我收到编译器错误：构造函数 JDatePanelImpl(UtilDateModel) 未定义。建议的修复方法是：添加参数以匹配 JDatePanelImpl(DateModel, Properties)。什么应该作为属性参数传入？

conn.setLayout(null);
UtilDateModel model = new UtilDateModel();
//model.setDate(20,04,2014);

JDatePickerImpl datePicker = new JDatePickerImpl(datePanel);
f1.add(datePicker);
}

Assuming you are using 1.3.4, then the constructor requirements have changed...
假设您使用的是 1.3.4，那么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());
Using this AbstractFormatter...
使用这个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 "";
}
}

Just use properties in the constructor of JDatePanelImpl
只需在构造函数中使用属性 JDatePanelImpl
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);
