Overview

The CalendarCol class is a simple calendar window where you can edit

the date:

http://visualruby.net/img/calendar.jpg

This class is very useful when you want to display and edit dates
in a VR::ListView.  You can define a column with the type VR::CalendarCol
and the column will display as a date, and when the user clicks on the
date, a calendar window will appear so he/she can edit it:

 @view = VR::ListView.new(:name => String, :birthday => VR::CalendarCol)
 row = @view.add_row
 row[:name] = "Eric"
 row[:birthday] = VR::CalendarCol.new(DateTime.new(1966, 7, 14))

See the example project, "listview_objects" for more.
