When I try to create a custom module that shows two tabs on the main page with the option to change titles, backgrounds, and colors, I was successful in adding the module's tab in the admin area but wasn't able to add the layout and template.
any one can explain please , how i can do this?
here the xml files:
app/etc/modules/Lern_Sample.xml/
<?xml version="1.0"?> <config> <modules> <Lern_Sample> <active>true</active> <codePool>local</codePool> <depends> <Mage_Adminhtml /> </depends> </Lern_Sample> </modules> app/code/local/Lern/Sample/Block/Adminhtml/Sample/
grid.php
`class Lern_Sample_Block_Adminhtml_Sample_Grid extends Mage_Adminhtml_Block_Widget_Grid { public function __construct() { parent::__construct(); } }` Sample.php
class Lern_Sample_Block_Sample extends Mage_Payment_Block_Form { public function __construct() {} } app/code/local/Lern/Sample/controllers/Adminhtml/IndexController.php
class Lern_Sample_Adminhtml_IndexController extends Mage_Adminhtml_Controller_Action { public function indexAction() { $this->loadLayout(); $this->renderLayout(); } } design/adminhtml/default/default/layout/sample.xml
