Re: [polymer-dev] where can i find a list of "on-events"?

2016-02-11 Thread 'Arthur Evans' via Polymer 
If you're using a paper-menu (or a paper-listbox) inside a
paper-dropdown-menu as shown in the example on the paper-dropdown-menu
docs, then the paper-menu fires an iron-select event when the selected item
changes (
https://elements.polymer-project.org/elements/paper-menu#event-iron-select).
The paper-dropdown-menu fires events when it's opened or closed.

Here's a bin showing listening to the iron-select event:

http://jsbin.com/juvojec/edit?html,console,output

So we're clear, there's no list of on- event attributes. Polymer supports
this as a general pattern. on- adds an event listener for
. That event name can be a standard DOM event like click
, a Polymer gesture
event like tap
,
or an element-specific event like iron-select.

As Karl said, any property with notify: true also generates an event. You
could also listen for _those_ with on-, like,
on-value-changed, on-selected-item-label-changed, and so on.

The paper-dropdown-menu doc is a little unclear, but the meaning of the 2nd
paragraph is that you can specify any menu element you like (paper-menu,
paper-listbox, or an element of your own). If you create a new element
here, it needs to fire an iron-select event when a new item is selected,
and the event's detail.item should be the selected item.

https://elements.polymer-project.org/elements/paper-dropdown-menu

I'll submit a PR to try and make this part of the API doc a little clearer.

Hope that helps.

You are right Karl that a property requirese `notify: true` to fire 
on-propertyname-changed events.

Ahhh gotcha, that would be the 'on-value-change' or maybe -changed I forget
which it is... basically ANY property will fire an on-*-change[d] event,
which I believe requires that property to be notify:true (but could be
wrong).

Re: [polymer-dev] where can i find a list of "on-events"?

2016-02-08 Thread Colin Cannon 
Hi Karl, thanks for the reply.  I did see those events listed, but I am 
looking for something like an on-change event to fire when the selected 
value of the drop down changes.  For instance, right now as a test I have:

on-click="_test"

as an attribute in my paper-dropdown-menu element, and that is not listed 
anywhere on that doc page, but it does fire an event when clicked.  

*maybe I should have asked for on-event attributes
