Vaadin MVP ValueChangeListener

General
1

Hello Team,
I am referring https://vaadin.com/web/magi/home/-/blogs/model-view-presenter-pattern-with-vaadin

I have just started with vaadin MVP example. Thank you for above example I created it and it’s working fine.

in above you passed the ClickListemer as argument in a new Button(caption, this) hence the listener is listening on every buttons. I appreciate the way it is working But how to do it for checkBox, textarea etc ? Because it does not have any constructor which takes *Listener(ValueChangeListener, ShortcutListener, ShortcutFocusListener) as a argument.

Please let me know if you need any other information from my side? Any pointers are highly appreciated.

Use add*Listener(*Listener). That is also the standard way to do it for a button, but the Button component has a “shortcut” version with a constructor parameter because for buttons you practically always want to use a listener.
