+dates. The field comes in two variations: [classname]#PopupDateField#,
 with a numeric input box and a popup calendar view, and
 [classname]#InlineDateField#, with the calendar view always visible. The
 [classname]#DateField# base class defaults to the popup variation.
 
-The example below illustrates the use of the [classname]#DateField# baseclass,
-which is equivalent to the [classname]#PopupDateField#. We set the initial time
-of the date field to current time by using the default constructor of the
-[classname]#java.util.Date# class.

-The [classname]#PopupDateField# provides date input using a text box for the
-date and time. As the [classname]#DateField# defaults to this component, the use
-is exactly the same as described earlier. Clicking the handle right of the date
-opens a popup view for selecting the year, month, and day, as well as time. Also
-the Down key opens the popup. Once opened, the user can navigate the calendar
-using the cursor keys.

 == Date and Time Resolution
 
 In addition to display a calendar with dates, [classname]#DateField# can also
-display the time in hours and minutes, or just the month or year. The visibility
-of the input components is controlled by __time resolution__, which you can set
-with [methodname]#setResolution()#. The method takes as its parameters the
-lowest visible component, [parameter]#DateField.Resolution.DAY# for just dates
-and [parameter]#DateField.Resolution.MIN# for dates with time in hours and
-minutes. Please see the API Reference for the complete list of resolution
-parameters.
