    <title>Dijit-Specific Form Elements</title>

    <para>
        Each form dijit for which a view helper is provided has a corresponding
        <classname>Zend_Form</classname> element. All of them have the following methods
        available for manipulating dijit parameters:
    </para>

    <itemizedlist>
        <listitem><para>
                <methodname>setDijitParam($key, $value)</methodname>: set a single dijit
                parameter. If the dijit parameter already exists, it will be
                overwritten.
        </para></listitem>

        <listitem><para>
                <methodname>setDijitParams(array $params)</methodname>: set several dijit
                parameters at once. Any passed parameters matching those
                already present will overwrite.
        </para></listitem>

        <listitem><para>
                <methodname>hasDijitParam($key)</methodname>: If a given dijit parameter
                is defined and present, return TRUE, otherwise return FALSE.
        </para></listitem>

        <listitem><para>
                <methodname>getDijitParam($key)</methodname>: retrieve the given dijit
                parameter. If not available, a null value is returned.
        </para></listitem>

        <listitem><para>
                <methodname>getDijitParams()</methodname>: retrieve all dijit parameters.
        </para></listitem>

        <listitem><para>
                <methodname>removeDijitParam($key)</methodname>: remove the given dijit
                parameter.
        </para></listitem>

        <listitem><para>
                <methodname>clearDijitParams()</methodname>: clear all currently defined
                dijit parameters.
        </para></listitem>
    </itemizedlist>

    <para>
        Dijit parameters are stored in the <code>dijitParams</code> public
        property. Thus, you can dijit-enable an existing form element simply by
        setting this property on the element; you simply will not have the
        above accessors to facilitate manipulating the parameters.
    </para>

    <para>
        Additionally, dijit-specific elements implement a different list of
        decorators, corresponding to the following:
    </para>

    <programlisting language="php"><![CDATA[
$element->addDecorator('DijitElement')
        ->addDecorator('Errors')
        ->addDecorator('HtmlTag', array('tag' => 'dd'))
        ->addDecorator('Label', array('tag' => 'dt'));
]]></programlisting>

    <para>
        In effect, the DijitElement decorator is used in place of the standard
        ViewHelper decorator.
    </para>

    <para>
        Finally, the base Dijit element ensures that the Dojo view helper path
        is set on the view.
    </para>

    <para>
        A variant on DijitElement, DijitMulti, provides the functionality of
        the <code>Multi</code> abstract form element, allowing the developer to
        specify 'multiOptions' -- typically select options or radio options.
    </para>

    <para>
        The following dijit elements are shipped in the standard Zend
        Framework distribution.
    </para>

    <sect3 id="zend.dojo.form.elements.button">

                element</link>, it does implement the same functionality, and
            can be used as a drop-in replacement for it. The following
            functionality is exposed:
        </para>

        <itemizedlist>
            <listitem><para>
                <methodname>getLabel()</methodname> will utilize the element name as the
                button label if no name is provided. Additionally, it will
                translate the name if a translation adapter with a matching
                translation message is available.
            </para></listitem>

            <listitem><para>
                <methodname>isChecked()</methodname> determines if the value submitted
                matches the label; if so, it returns true. This is useful for
                determining which button was used when a form was submitted.
            </para></listitem>
        </itemizedlist>

        <para>
            Additionally, only the decorators <code>DijitElement</code> and
            <code>DtDdWrapper</code> are utilized for Button elements.
        </para>

                linkend="zend.dojo.view.dijit.form">dijit view helper
                documentation</link>, ComboBoxes are a hybrid between select
            and text input, allowing for autocompletion and the ability to
            specify an alternate to the options provided. FilteringSelects are
            the same, but do not allow arbitrary input.
        </para>

        <note>
            <title>ComboBoxes return the label values</title>

            <para>
                ComboBoxes return the label values, and not the option values,
                which can lead to a disconnect in expectations. For this reason,
                ComboBoxes do not auto-register an <code>InArray</code>
                validator (though FilteringSelects do).
            </para>
        </note>

        <para>
            The ComboBox and FilteringSelect form elements provide accessors and mutators for
            examining and setting the select options as well as specifying a
            dojo.data datastore (if used). They extend from DijitMulti, which
            allows you to specify select options via the
            <methodname>setMultiOptions()</methodname> and <methodname>setMultiOption()</methodname>
            methods. In addition, the following methods are available:

                set.

            <listitem><para>
                <methodname>setStoreId($identifier)</methodname>: set the store identifier
                variable (usually referred to by the attribute 'jsId' in Dojo).
                This should be a valid javascript variable name.

                dojo.data.ItemFileReadStore datastore would expect a 'url'

        <para>
            By default, if no dojo.data store is registered with the element,

            validates against the array keys of registered options. You can
            disable this behavior by either calling
            <methodname>setRegisterInArrayValidator(false)</methodname>, or by passing a
            false value to the <code>registerInArrayValidator</code>
            configuration key.

            ValidationTextBox provides the ability to add validations and constraints to a text
            input. Internally, it derives from <link
                linkend="zend.dojo.form.elements.textBox">TextBox</link>, and adds the following
            accessors and mutators for manipulating dijit parameters:

                <methodname>setInvalidMessage($message)</methodname> and
                <methodname>getInvalidMessage()</methodname>: set and retrieve the tooltip
                message to display when the value does not validate.
            </para></listitem>

                <methodname>setPromptMessage($message)</methodname> and
                <methodname>getPromptMessage()</methodname>: set and retrieve the tooltip
                message to display for element usage.

            <listitem><para>
                <methodname>setRegExp($regexp)</methodname> and <methodname>getRegExp()</methodname>:
                set and retrieve the regular expression to use for validating
                the element. The regular expression does not need boundaries
                (unlike PHP's preg* family of functions).
            </para></listitem>

            <listitem><para>
                <methodname>setConstraint($key, $value)</methodname> and
                <methodname>getConstraint($key)</methodname>: set and retrieve additional
                constraints to use when validating the element; used primarily
                with subclasses. Constraints are stored in the 'constraints'
                key of the dijit parameters.

                constraints to use when validating the element; used primarily
                with subclasses.

            <listitem><para>
                <methodname>hasConstraint($key)</methodname>: test whether a given
                constraint exists.

                The following will create a ValidationTextBox that requires a
                single string consisting solely of word characters (i.e., no
                spaces, most punctuation is invalid).

        <para>
            VerticalSlider is the sibling of <link
                linkend="zend.dojo.form.elements.horizontalSlider">HorizontalSlider</link>,
            and operates in every way like that element. The only real
            difference is that the 'top*' and 'bottom*' methods are replaced by
            'left*' and 'right*', and instead of using HorizontalRule and
            HorizontalRuleLabels, VerticalRule and VerticalRuleLabels should be
            used.

                The following will create a vertical slider selection with
                integer values ranging from -10 to 10. The left will have labels
                at the 20%, 40%, 60%, and 80% marks. The right will have rules
                at 0, 50%, and 100%. Each time the value is changed, the hidden
                element storing the value will be updated.
