How to implement a long-press event using Polymer1.0?

It seems that a long-term event is not part of the Polymer specification.

How do you implement this?

I was thinking about using behavior and using down and up events with some debounce tricks to control such a new event, but that means I have to create my own element to use this behavior and cannot for example use it directly for any elements I need :

 <div on-long-press="_cheese">...</div>

which is not convenient.

Do you have other solutions?

You do not need to create a custom element for this. This is what polymer behavior refers to. They provide a way for different polymer elements to propagate common behavior.

Regarding the actual javascript for implementing long-term printing, you can get ideas from this question .

You can use the Vaadin gesture for this.

<paper-button on-vaadin-long-touch="function"></paper-button>
