Combine ValoTheme styles of Notification

Which way can I combine styles of Notification when addStyleName method is missing?

You can use setStyleName and pass multiple names separated by white space like this

setStyleName("warning closable"); with notification type you control if it’s for example a Tray notification or regular popup notification.
Pleas take a look at the source code or Valo theme’s demo at github:

You can also take a look at the demo app at!common and with your html inspector see the css classes added to v-Notification element.

Thank you Peter for quick answer and I appreciate the work of whole Vaadin team
