require_once( $mainframe->getPath( 'toolbar_html' ) );

if($task) {

  switch($task) {
    case 'new':  
    case 'edit': 
      $act = "edit";
      break;

  }
}

if ($act) {

  switch ( $act ) {

    case 'edit':
      menuHello_world::EDIT_MENU();
      break;
   
    case 'text':
      menuHello_world::TEXT_MENU();
      break;

  }
}   

?>

Now let's look at how the file works:

require_once( $mainframe->getPath( 'toolbar_html' ) );
Works the same as requiring the admin.hello_world.html.php file in admin.hello_world.php

if($task) {

  switch($task) {
    case 'new':  
    case 'edit': 
      $act = "edit";
      break;

  }
}

"new" and "edit" will use the same toolbar.

    case 'edit':
      menuHello_world::EDIT_MENU();
      break;
This tells toolbar.hello_world.html.php which function to use.
