Event handler signature

public void event_onExtendOrderInvoicesToolbar(Shop_Orders $controller)
$controller Shop_Orders specifies the controller object.
Allows to add new button to the toolbar above the Invoice List on the Order Preview page in the Administration Area. The event handler should accept a single parameter - the controller object, which you can use for rendering a partial, containing new buttons. The following example adds the "Generate subscription invoice" button to the toolbar. Similar code used in the Subscriptions Module. 
public function subscribeEvents()
{
  Backend::$events->addEvent('shop:onExtendOrderInvoicesToolbar', $this, 'extend_invoices_toolbar');
}

public function extend_invoices_toolbar($controller)
{
  $controller->renderPartial(PATH_APP.'/modules/subscriptions/partials/_invoices_toolbar.htm');
}

// Example of the _invoices_toolbar.htm partial

<div class="separator">&nbsp;</div>
<?= backend_ctr_button(
  'Generate subscription invoice', 
  'generate_subscription_invoice', 
  array('href'=>'#', 'onclick'=>"
    new PopupForm('onCustomEvent', {
      closeByEsc: false, 
      ajaxFields: {custom_event_handler: 'subscriptions:onGenerateInvoice'}
  }); return false;
")) ?>
