Knowing what week is visibile on a Calendar

[andmej]

I have a Calendar, that shows some events queried from a JSON file. Currently the Calendar requests all events in all time intervals, which is very slow because there are too many.

I want to query only the events on the visible week on the calendar. So I need two things:

(i) Knowing what week is being viewed currently on the calendar
(ii) Generating an event or something similar when the user clicks on the upper-left arrows to change between weeks, as to update the data accordingly.

How can this be done?

Thanks for your valuable support.

You want getChosenDate() and the DateChanged event. Be sure you have the latest from SVN.
