Hey,
I have modified GWT DatePicker ,I have added Month and Year Selector on it.
1) DatePickerWithYearSelectorNew.java
import com.google.gwt.user.datepicker.client.CalendarModel;
import com.google.gwt.user.datepicker.client.DatePicker;
import com.google.gwt.user.datepicker.client.DefaultCalendarView;
public class DatePickerWithYearSelectorNew extends DatePicker {
public DatePickerWithYearSelectorNew() {
super(new MonthAndYearSelectorWithYear(), new DefaultCalendarView(),
new CalendarModel());
MonthAndYearSelectorWithYear monthSelector = (MonthAndYearSelectorWithYear)
this
.getMonthSelector();
monthSelector.setPicker(this);
monthSelector.setModel(this.getModel());
}
public void refreshComponents() {
super.refreshAll();
}
}
2) MonthAndYearSelectorWithYear.java
import java.util.Date;
