关于样式为SWT.CALENDAR的DateTime小部件

Question

我们如何检测用户是否在DateTime时间上以SWT.CALENDAR样式单击（使用鼠标）在DateTime月份，日期或年份。

Answer 1

Actual purpose was to get the selected date and dispose the calendar popup for single click on date, but on implementing this the problem was the calendar gets disposed even when we click on the year or month, however i have implemented it myself thanks all for your respose

if(calendarWidget.getYear() == defaultYear && calendarWidget.getMonth() == defaultMonth)
{
    //here i am getting the selected date and saving it
    defaultYear = calendarWidget.getYear();
    defaultMonth = calendarWidget.getMonth();
    shell.dispose();
}
else
{
    defaultYear = calendarWidget.getYear();
    defaultMonth = calendarWidget.getMonth();
}

here default month and year are the default selected date in calendar widget.

Based on Shiva answer I've added one more condition. If you choose a day from another month than current, it will hide popup. Example: You see popup with March and you select one of the first days of April.

if((calendar.getYear() == defaultYear && calendar.getMonth() == defaultMonth) ||
                    (calendar.getYear() == defaultYear && calendar.getMonth() != defaultMonth && calendar.getDay() != defaultDay))
            {
                //here i am getting the selected date and saving it
                defaultYear = calendar.getYear();
                defaultMonth = calendar.getMonth();
                defaultDay = calendar.getDay();
                popup.dispose();
            }
            else
            {
                defaultYear = calendar.getYear();
                defaultMonth = calendar.getMonth();
                defaultDay = calendar.getDay();
            }

If you mean org.eclipse.swt.widgets.DateTime it inherit addMouseListener .

MouseListener interface has method:

public void mouseClicked(MouseEvent evt)

and MouseEvent has methods:

getX()
getY()

So you can get relative position of mouse, when it is clicked and calculate on which element it is, depending on component properties.
