The ``z3c.form`` library provides a form framework and widgets. This document
ensures that we implement a widget for each field defined in
``zope.schema``. Take a look at the different widget doctest files for more
information about the widgets.

  >>> import zope.schema
  >>> from z3c.form import browser

Let's setup all required adapters using zcml. This makes sure we test the real
configuration.

  >>> from zope.configuration import xmlconfig
  >>> import zope.component
  >>> import zope.app.component
  >>> import zope.app.security
  >>> import zope.i18n
  >>> import z3c.form
  >>> xmlconfig.XMLConfig('meta.zcml', zope.component)()
  >>> xmlconfig.XMLConfig('meta.zcml', zope.app.component)()
  >>> xmlconfig.XMLConfig('meta.zcml', zope.app.security)()
  >>> xmlconfig.XMLConfig('meta.zcml', zope.i18n)()
  >>> xmlconfig.XMLConfig('meta.zcml', z3c.form)()
  >>> xmlconfig.XMLConfig('configure.zcml', zope.app.security)()
  >>> xmlconfig.XMLConfig('configure.zcml', z3c.form)()

This utility is setup by hand, since its ZCML loads to many unwanted files:

  >>> import zope.component
  >>> import zope.i18n.negotiator
  >>> zope.component.provideUtility(zope.i18n.negotiator.negotiator)

also define a helper method for test the widgets:

  >>> from z3c.form import interfaces
  >>> from z3c.form.testing import TestRequest
  >>> def setupWidget(field):
  ...     request = TestRequest()
  ...     widget = zope.component.getMultiAdapter((field, request),
  ...         interfaces.IFieldWidget)
  ...     widget.id = 'foo'
  ...     widget.name = 'bar'
  ...     return widget


ASCII
-----

  >>> field = zope.schema.ASCII(default='This is\n ASCII.')
  >>> widget = setupWidget(field)
  >>> widget.update()

  >>> widget.__class__
  <class 'z3c.form.browser.textarea.TextAreaWidget'>

  >>> interfaces.IDataConverter(widget)
  <FieldDataConverter converts from ASCII to TextAreaWidget>

  >>> print widget.render()
  <textarea id="foo" name="bar" class="textarea-widget required ascii-field">This is
   ASCII.</textarea>

  >>> widget.mode = interfaces.DISPLAY_MODE
  >>> print widget.render()
  <span id="foo" class="textarea-widget required ascii-field">This is
   ASCII.</span>


ASCIILine
---------

  >>> field = zope.schema.ASCIILine(default='An ASCII line.')
  >>> widget = setupWidget(field)
  >>> widget.update()

  >>> widget.__class__
  <class 'z3c.form.browser.text.TextWidget'>

  >>> interfaces.IDataConverter(widget)
  <FieldDataConverter converts from ASCIILine to TextWidget>

  >>> print widget.render()
  <input type="text" id="foo" name="bar"
         class="text-widget required asciiline-field" value="An ASCII line." />

  >>> widget.mode = interfaces.DISPLAY_MODE
  >>> print widget.render()
  <span id="foo" class="text-widget required asciiline-field">An ASCII line.</span>

Bool
----

  >>> field = zope.schema.Bool(default=True, title=u"Check me")
  >>> widget = setupWidget(field)
  >>> widget.update()

  >>> widget.__class__
  <class 'z3c.form.browser.radio.RadioWidget'>

  >>> interfaces.IDataConverter(widget)
  <SequenceDataConverter converts from Bool to RadioWidget>

  >>> print widget.render()
  <span class="option">
    <label for="foo-0">
      <input type="radio" id="foo-0" name="bar:list"
             class="radio-widget required bool-field" value="true"
             checked="checked" />
      <span class="label">yes</span>
    </label>
  </span><span class="option">
    <label for="foo-1">
      <input type="radio" id="foo-1" name="bar:list"
             class="radio-widget required bool-field" value="false" />
      <span class="label">no</span>
    </label>
  </span>
  <input name="bar-empty-marker" type="hidden" value="1" />

  >>> widget.mode = interfaces.DISPLAY_MODE
  >>> print widget.render()
  <span id="foo" class="radio-widget required bool-field"><span
      class="selected-option">yes</span></span>

For the boolean, the checkbox widget can be used as well:

  >>> from z3c.form.browser import checkbox
  >>> widget = checkbox.CheckBoxFieldWidget(field, TestRequest())
  >>> widget.id = 'foo'
  >>> widget.name = 'bar'
  >>> widget.update()

  >>> print widget.render()
  <span class="option">
    <input type="checkbox" id="foo-0" name="bar:list"
           class="checkbox-widget required bool-field" value="true"
           checked="checked" />
    <label for="foo-0">
      <span class="label">yes</span>
    </label>
  </span><span class="option">
    <input type="checkbox" id="foo-1" name="bar:list"
           class="checkbox-widget required bool-field" value="false" />
    <label for="foo-1">
      <span class="label">no</span>
    </label>
  </span>
  <input name="bar-empty-marker" type="hidden" value="1" />

  >>> widget.mode = interfaces.DISPLAY_MODE
  >>> print widget.render()
  <span id="foo" class="checkbox-widget required bool-field"><span
      class="selected-option">yes</span></span>

We can also have a single checkbox button for the boolean.

  >>> widget = checkbox.SingleCheckBoxFieldWidget(field, TestRequest())
  >>> widget.id = 'foo'
  >>> widget.name = 'bar'
  >>> widget.update()

  >>> print widget.render()
  <span class="option">
    <input type="checkbox" id="foo-0" name="bar:list"
           class="single-checkbox-widget required bool-field"
           value="selected" checked="checked" />
    <label for="foo-0">
      <span class="label">Check me</span>
    </label>
  </span>
  <input name="bar-empty-marker" type="hidden" value="1" />

  >>> widget.mode = interfaces.DISPLAY_MODE
  >>> print widget.render()
  <span id="foo"
        class="single-checkbox-widget required bool-field"><span
      class="selected-option">Check me</span></span>

Note that the widget label is not repeated twice:

  >>> widget.label
  u''


Button
------

  >>> from z3c.form import button
  >>> field = button.Button(title=u'Press me!')
  >>> widget = setupWidget(field)
  >>> widget.update()

  >>> widget.__class__
  <class 'z3c.form.browser.submit.SubmitWidget'>

  >>> print widget.render()
  <input type="submit" id="foo" name="bar"
         class="submit-widget button-field" value="Press me!" />

  >>> widget.mode = interfaces.DISPLAY_MODE
  >>> print widget.render()
  <input type="submit" id="foo" name="bar"
         class="submit-widget button-field" value="Press me!"
         disabled="disabled" />

There exists an alternative widget for the button field, the button widget. It
is not used by default, but available for use:

  >>> from z3c.form.browser.button import ButtonFieldWidget
  >>> widget = ButtonFieldWidget(field, TestRequest())
  >>> widget.id = "foo"
  >>> widget.name = "bar"

  >>> widget.update()
  >>> print widget.render()
  <input type="button" id="foo" name="bar"
         class="button-widget button-field" value="Press me!" />

  >>> widget.mode = interfaces.DISPLAY_MODE
  >>> print widget.render()
  <input type="button" id="foo" name="bar"
         class="button-widget button-field" value="Press me!"
         disabled="disabled" />

  >>> interfaces.IDataConverter(widget)
  <FileUploadDataConverter converts from Bytes to FileWidget>

  >>> print widget.render()
  <input type="file" id="foo" name="bar" class="file-widget required bytes-field" />

  >>> widget.mode = interfaces.DISPLAY_MODE
  >>> widget.render().strip('\n')
  u'<span id="foo" class="file-widget required bytes-field">Default bytes</span>'

  >>> interfaces.IDataConverter(widget)
  <FieldDataConverter converts from BytesLine to TextWidget>

  >>> print widget.render()
  <input type="text" id="foo" name="bar" class="text-widget required bytesline-field"
         value="A Bytes line." />

  >>> widget.mode = interfaces.DISPLAY_MODE
  >>> print widget.render()
  <span id="foo" class="text-widget required bytesline-field">A Bytes line.</span>


Choice
------

  >>> from zope.schema import vocabulary
  >>> terms = [vocabulary.SimpleTerm(*value) for value in
  ...          [(True, 'yes', 'Yes'), (False, 'no', 'No')]]
  >>> vocabulary = vocabulary.SimpleVocabulary(terms)
  >>> field = zope.schema.Choice(default=True, vocabulary=vocabulary)
  >>> widget = setupWidget(field)
  >>> widget.update()

  >>> widget.__class__
  <class 'z3c.form.browser.select.SelectWidget'>

  <SequenceDataConverter converts from Choice to SelectWidget>

  >>> print widget.render()
  <select id="foo" name="bar:list" class="select-widget required choice-field"
          size="1">
    <option id="foo-0" value="yes" selected="selected">Yes</option>
    <option id="foo-1" value="no">No</option>
  </select>
  <input name="bar-empty-marker" type="hidden" value="1" />

Id
--

  >>> field = zope.schema.Id(default='z3c.form')
  >>> widget = setupWidget(field)
  >>> widget.update()

  >>> widget.__class__
  <class 'z3c.form.browser.text.TextWidget'>

  >>> interfaces.IDataConverter(widget)
  <FieldDataConverter converts from Id to TextWidget>

  >>> print widget.render()
  <input type="text" id="foo" name="bar" class="text-widget required id-field"
         value="z3c.form" />

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


ImageButton
-----------

Let's say we have a simple image field that uses the ``pressme.png`` image.

  >>> from z3c.form import button
  >>> field = button.ImageButton(
  ...     image=u'pressme.png',
  ...     title=u'Press me!')

When the widget is created, the system converts the relative image path to an
absolute image path by looking up the resource. For this to work, we have to
setup some of the traversing machinery:

  # Traversing setup
  >>> from zope.traversing import testing
  >>> testing.setUp()

  # Resource namespace
  >>> import zope.component
  >>> from zope.traversing.interfaces import ITraversable
  >>> from zope.traversing.namespace import resource
  >>> zope.component.provideAdapter(
  ...     resource, (None,), ITraversable, name="resource")
  >>> zope.component.provideAdapter(
  ...     resource, (None, None), ITraversable, name="resource")

  # Register the "pressme.png" resource
  >>> from zope.app.publisher.browser.resource import Resource
  >>> testing.browserResource('pressme.png', Resource)

Now we are ready to instantiate the widget:

  >>> widget = setupWidget(field)
  >>> widget.update()

  >>> widget.__class__
  <class 'z3c.form.browser.image.ImageWidget'>

  >>> print widget.render()
  <input type="image" id="foo" name="bar"
         class="image-widget imagebutton-field"
         src="http://127.0.0.1/@@/pressme.png"
         value="Press me!" />

  >>> widget.mode = interfaces.DISPLAY_MODE
  >>> print widget.render()
  <input type="image" id="foo" name="bar"
         class="image-widget imagebutton-field"
         src="http://127.0.0.1/@@/pressme.png"
         value="Press me!" disabled="disabled" />

  >>> widget = setupWidget(field)

  >>> interfaces.IDataConverter(widget)
  <IntegerDataConverter converts from Int to TextWidget>

  >>> print widget.render()
  <input type="text" id="foo" name="bar" class="text-widget required int-field"
         value="1,200" />

  ...     default=['foo\nfoo', 'bar\nbar'])
  >>> widget = setupWidget(field)
  >>> widget.update()

  >>> widget.__class__
  <class 'z3c.form.browser.multi.MultiWidget'>

  >>> interfaces.IDataConverter(widget)
  <MultiConverter converts from List to MultiWidget>
