Listeners on generated forms

[george-oakling]

Lets say I have a form, which is generated like below. How could I add listeners for onSuccess on this type of form? Thanks a lot :)

class SpecialForm extends Nette\Object {
   public function create() {
     $form = new UI\Form;
     return $form;
   }
}

class SpecialPresenter {

   /** @inject */
   public $specialForm;

   protected function createComponentSpecialForm() {
      return $this->specialForm->create();
   }
}

Hi, technically, you can. But this lib is not able to autowire events in an instance created like that. You'd have to wire the events by hand

class SpecialForm extends Nette\Object {
   private $evm;
   public function __construct(EventManager $evm) { $this->evm = $evm; }

   public function create() {
     $form = new UI\Form;
     $form->onSuccess = $this->evm->createEvent([get_class($form), 'onSuccess']);
     // ...
     return $form;
   }
}

But your example does not contain a generated form, but rather created by a custom factory. If you really create the form using generated factory, this lib should be able to autowire it.

Thanks a lot, it was much easier to change the logic to standard generated factory and it is working now as expected.
