Custom form element - widgets

Question

Is it possible to create a custom form element that can be used in widget instance creation?

Fields used in widgets is setup using widget.xml ,for example:

        <my_field>
            <label>My Field</label>
            <type>textarea</type>
        </my_field>

How can i replace textarea with a completely custom form element ?

Answer 1

What you need to do is replace textarea with a block representing your new element.

<type>your_module/widget_new_element</type>

The you can create a class Your_Module_Block_Widget_New_Element that extends Mage_Adminhtml_Block_Widget_Form_Renderer_Fieldset_Element. Then depending on what you want your new element to do you can add customizations to this new block.
