   Hi all,
   I've been asking recently how to write a correct oop plugin and thnaks to the ansqwers i've been able to start a good skeleton.
   But i'm stuck with the help screen.
   I want to have contextual help for each of my menu/submenus
   I read this and this but i stll can't manage to display any help screen whatsoever.
   I'm on a clean WP 3.3, so no risk of upgrade problem here.

   Here what i have sofar :
   file is myplugin1.php

   if ( ! class_exists('myplugin1') )
   {
   	class myplugin1
   	{
   		private $textdom = 'myplugin1';//traduction prefix
   
   		public function __construct()
   		{
   			if ( is_admin() )
   			{
   				$this->register_hooks();//install stuff
   				add_action('admin_menu', array(&$this, 'myplugin1_adminmenu'));
   			}
   		}
   ...
   		public function myplugin1_adminmenu()
   		{
   			$pluginpath = $this->pluginURL;
   			if (function_exists('add_menu_page'))
   			{
   				$menu_page = add_menu_page(__('My main menu page title', $this->textdom), __('My main menu title', $this->textdom), 'manage_options', 'mainmenu', array(&$this, 'mainmenu'), $pluginpath.'images/menuicon.gif' );
   			}
   			if (function_exists('add_submenu_page'))
   			{
   				$submenu_page = add_submenu_page('mainmenu', __('My main submenu page title', $this->textdom), __('My main submenu title', $this->textdom), 'manage_options', 'mysubmenu', array(&$this, 'mysubmenu') );
   			}
   		}
   		public function mainmenu()
   		{
   			echo '
   			<div class="wrap"><div id="icon-options-general" class="icon32"><br></div>
   			<h2>Main menu</h2>
   			<p>Menu content</p>
   			</div>';
   			$screen = get_current_screen();
   			$screen->add_help_tab( array(
   				'id' => $screen->id,
   				'title' => __('Menu help'),
   				'content' => __('My Help Content'),));
   		}
   		public function mysubmenu()
   		{
   			echo '
   			<div class="wrap"><div id="icon-options-general" class="icon32"><br></div>
   			<h2>Submenu</h2>
   			<p>Submenu content</p>
   			</div>';
   			$screen = get_current_screen();
   			$screen->add_help_tab( array(
   				'id' => $screen->id,
   				'title' => __('Submenu help'),
   				'content' => __('My Submenu Help Content'),));
   		}
   	}
   }
   $myplugin1_instance = new myplugin1();

   But neither the menu nor the submenu display the help.

   Is this a problem with my code or is there a specific syntax for plugin help.
   Thanks in advance

   if i make a dump of $screen->add_help_tab, the data are here. But there is no help menu on the screen

   Does it need anything else than

   $screen = get_current_screen();
   $screen->add_help_tab( array(
   	'id' => $screen->id,
   	'title' => __('Submenu help'),
   	'content' => __('My Submenu Help Content'),));

   to display a menu tab ?
   Do i need to require some extra file before ?

   ok, i found a solution here

   I saw nowhere else in the codex example or in the topics concerning this point that a WP_Screen object had to be used this way :

   i saw
   

   $screen = get_current_screen();
   $screen->add_help_tab( array( $id, $title, $content, $callback ) );

   and not
   

   $screen = WP_Screen::get($hook);
   $screen->add_help_tab( array( $id, $title, $content, $callback ) );

   hope this will help someone else.
