Admin – Tabs with Grids in Admin Extension

I have been searching for an example of how to write an extension page with tabs and on each tab is a grid. I don't need a form, just the mass action too. Any one have a link to this? What I'm doing is converting something I have which is under /myext/mycontrol/index/ which I would like to keep and not end up with /admin/mycontrol/index.

An example would be ideal, but if someone can layout the files, for two tabs with grids and the classes, that would be enough I know it. Here is what I have so far for the blocks and controllers.

+-Block
|+-Mycontrol.php
|+-Mycontrol
| |+-Tabs.php
| |+-Action1.php
| |+-Action1
|   |+-Grid.php
+-controllers
 |+-MycontrolController.php

I see the page but no tabs. Here are the file stubs with out the method, as I'm sure that is the issue at hand here.

admin\Mycomp\Myext\Block\Mycontrol.php

<?php
class Mycomp_Myext_Block_Mycontrol extends Mage_Adminhtml_Block_Widget_Grid
    implements Mage_Adminhtml_Block_Widget_Tab_Interface {

    public function __construct() {
        $this->_blockGroup = 'mycontrol';
        $this->_controller = 'media';
        $this->_headerText = Mage::helper('myext')->__('Welcome');
        parent::__construct();
    }


}

admin\Mycomp\Myext\Block\Mycontrol\Tabs.php

<?php
class Mycomp_Myext_Block_Mycontrol_Tabs extends Mage_Adminhtml_Block_Widget_Tabs {
    public function __construct(){
        parent::__construct();
        $this->setId('myext_tabs');
        $this->setTitle(Mage::helper('myext')->__('media controll'));
    }
    protected function _beforeToHtml(){
        $activeSection = $this->_getActiveSection();
        //normal stuff
        return parent::_beforeToHtml();
    }

    protected function _getActiveSection($default = 'orphaned'){
        //normal stuff
        return $activeSection;
    }
}

admin\Mycomp\Myext\Block\Mycontrol\Action1.php

class Mycomp_Myext_Block_Mycontrol_Action1 extends Mage_Adminhtml_Block_Widget_Grid_Container{
    public function __construct(){
        $this->_controller = 'mycontrol_action1';
        $this->_blockGroup = 'mycomp_myext';
        $this->_headerText = Mage::helper('myext')->__('Find Orphaned Images');
        parent::__construct();
        $this->_removeButton('add');
    }

    public function getCreateUrl() {
        return '';
    }

    public function getHeaderCssClass() {
        return '';
    }
}

admin\Mycomp\Myext\Block\Mycontrol\Action1\Grid.php

<?php

class Mycomp_Myext_Block_Mycontrol_Action1_Grid extends Mage_Adminhtml_Block_Widget_Grid {
    public function __construct()
    {
        parent::__construct();
        $this->setId('mycontrol_action1Grid');
        $this->setDefaultSort('prod_id');
        $this->setDefaultDir('ASC');
        $this->setSaveParametersInSession(true);
        $this->setUseAjax(true);
    }

    public function getId(){
        return 'myext_tabs_action1_section_content';
    }

    protected function _prepareCollection(){
        //normal stuff
        return parent::_prepareCollection();
    }

    protected function _prepareColumns(){
        //normal stuff
        return parent::_prepareColumns();
    }

    protected function _prepareMassaction(){
        //normal stuff
        return $this;
    }
}

Something tells me it's just in this order I'm messing up, but for the life of me I can't find one darn example that is not talking about adding tabs to the product page or tabs, edit, and forms. Can some one lay it out?

Update
I have been trying different ways to make this happen. Googling has not help. I do recall some wiki that had an example of on the magento site but I can't find that either. If anyone has the ability, a layout of the files needed and the classes is all I need. A good point in the right direction.

As I understand, I should be close, and tried (I can't seem to find the reference now but something like) $this->add_left() but that was not working either.
