how to implement double click event over vaadin calender

Hello everybody

I have requirement to open a window when a double click event occurs over a particular cell in
VAADIN Calendar
, either in weekly mode or in daily mode. My client does not like drag event rather he wants a double click event to open a window for appointment. But i did not know how to do this.

Also i need to get the time as we can get date time value when we drag over the calendar.

Please help me…
