All necessary components are set up in the testclass to make sure that
we test the real configuration. Let's render the widgets in different
modes and try to extract the value form an request.

  >>> import datetime
  >>> import z3c.form
  >>> import zope.schema

  >>> field = zope.schema.Date(default=datetime.date(2007, 4, 1))
  >>> widget = self.setupWidget(field)
  >>> widget.update()
  >>> widget.extract() is z3c.form.interfaces.NOVALUE
  True


INPUT_MODE
----------

  >>> widget.mode == z3c.form.interfaces.INPUT_MODE
  True
  >>> print widget.render()
  <input type="text" id="foo-day" name="bar-day"
         class="date-widget required date-field" size="2"
         maxlength="2" value="1" /> /
  <select id="foo-month" name="bar-month"
          class="date-widget required date-field">
      <option value="1">January</option>
      <option value="2">February</option>
      <option value="3">March</option>
      <option value="4" selected="selected">April</option>
      <option value="5">May</option>
      <option value="6">June</option>
      <option value="7">July</option>
      <option value="8">August</option>
      <option value="9">September</option>
      <option value="10">October</option>
      <option value="11">November</option>
      <option value="12">December</option>
  </select> /
  <input type="text" id="foo-year" name="bar-year"
         class="date-widget required date-field" alt=""
         accesskey="" size="4" maxlength="4" value="2007" />
  <input name="bar-empty-marker" type="hidden" value="1" />

  >>> widget.request = self.testrequest(
  ...     form={'bar-day': '1',
  ...           'bar-month': '4',
  ...           'bar-year': '2007',
  ...           'bar-empty-marker': '1'}
  ...     )
  >>> widget.extract()
  ('2007', '4', '1')


DISPLAY_MODE
------------

  >>> widget.mode = z3c.form.interfaces.DISPLAY_MODE
  >>> print widget.render()
  <span id="foo" class="date-widget required date-field">4/1/07</span>


HIDDEN_MODE
-----------

  >>> widget.mode = z3c.form.interfaces.HIDDEN_MODE
  >>> print widget.render()
  <input type="hidden" id="foo" name="bar"
           class="hidden-widget" value="4/1/07" />
  >>> widget.request = self.testrequest(
  ...     form={'bar': '4/1/07'}
  ...     )
  >>> widget.extract()
  ('2007', '4', '1')


INPUT_MODE and show_today_link
------------------------------

now lets enable show_today_link option to provide plain javascript for
inserting current date into the fields.

  >>> widget.mode = z3c.form.interfaces.INPUT_MODE
  >>> widget.show_today_link = True
  >>> print widget.render()
  <input type="text" id="foo-day" name="bar-day"
         class="date-widget required date-field" size="2"
         maxlength="2" value="1" /> /
  <select id="foo-month" name="bar-month"
          class="date-widget required date-field">
      <option value="1">January</option>
      <option value="2">February</option>
      <option value="3">March</option>
      <option value="4" selected="selected">April</option>
      <option value="5">May</option>
      <option value="6">June</option>
      <option value="7">July</option>
      <option value="8">August</option>
      <option value="9">September</option>
      <option value="10">October</option>
      <option value="11">November</option>
      <option value="12">December</option>
  </select> /
  <input type="text" id="foo-year" name="bar-year"
         class="date-widget required date-field" alt=""
         accesskey="" size="4" maxlength="4" value="2007" />
  <input name="bar-empty-marker" type="hidden" value="1" />
  <BLANKLINE>
  <BLANKLINE>
  <BLANKLINE>
  <a href="#" onclick="document.getElementById('foo-day').value = ...;document.getElementById('foo-month').value = ...;document.getElementById('foo-year').value = ...;return false;">Today</a>
