lets move on to block

";
return parent::_prepareLayout();
}
}
as like in magneto1.x here alo we have mode which default folder name is edit so create folder called edit then create below files
app\code\Sugarcode\Test\Block\Adminhtml\Lists\Edit\Form.php
<?php
namespace Sugarcode\Test\Block\Adminhtml\Lists\Edit;
/**
* Adminhtml blog post edit form block
*
* @author Magento Core Team <[email protected]>
*/
class Form extends \Magento\Backend\Block\Widget\Form\Generic
{
/**
* Prepare form
*
* @return $this
*/
protected function _prepareForm()
{
/** @var \Magento\Framework\Data\Form $form */
$form = $this->_formFactory->create(
['data' => ['id' => 'edit_form', 'action' => $this->getData('action'), 'method' => 'post']]
);
$form->setUseContainer(true);
$this->setForm($form);
return parent::_prepareForm();
}
}
app\code\Sugarcode\Test\Block\Adminhtml\Lists\Edit\tabs.php
<?php
namespace Sugarcode\Test\Block\Adminhtml\Lists\Edit;
/**
* Admin page left menu
*/
class Tabs extends \Magento\Backend\Block\Widget\Tabs
{
/**
* @return void
*/
protected function _construct()
{
parent::_construct();
$this->setId('post_tabs');
$this->setDestElementId('edit_form');
$this->setTitle(__('Information'));
}
}
now create folder called form and file main.php as per layout xml this will load in form container
if you need tabs then you need to use interface
class Main extends \Magento\Backend\Block\Widget\Form\Generic implements \Magento\Backend\Block\Widget\Tab\TabInterface
then interface function needs to be implemented here in below code below Prepare label for tab are for tabs
app\code\Sugarcode\Test\Block\Adminhtml\Lists\Edit\Tab\Main.php
<?php
