I stole this from SUIR, I didn't know we can do this. Very cool! :D

Radio group is necessary for accessibility purposes.
It can render just as a div. That will allow us to apply correct aria role and add keyboard handling.
See https://www.w3.org/TR/2017/WD-wai-aria-practices-1.1-20170628/examples/radio/radio-1/radio-1.html

mnajdova · 2018-09-10T09:40:16Z

@jurokapsiar so according to the post, we should render the RadioGroup and the Radio as div elements with the proper roles. Should I actually replace the implementation with

and style the ::before part to look like a radio button as part of this PR? If this is the final decision about how it should be defined, I would rather do this now then later.

-reverted the Radio to extend UIComponent

levithomason · 2018-09-10T16:24:08Z

We'll pause this work while we first style the radio. This will require an icon or pseudo elements and some custom event handling. Let's make sure that works before designing this next phase, groups.

-styles the Radio button with custom icon

mnajdova · 2018-09-10T19:17:02Z

As per our call, the RadioGroup is stopped for now, but there is an example added of how the buttons can be used as a group. The styles are also updated:

jurokapsiar · 2018-09-11T11:36:12Z

looking into accessibility, but it will take more time to come up with a working solution if we do not want to use default input as is.

looks like the missing thing is handling of the focused state.
let's try to use focused state introduced in #213

If not possible, you can take a look at https://www.w3.org/TR/wai-aria-practices/examples/radio/radio-1/radio-1.html which unfortunately does not work correctly with JAWS screen reader, but is a better starting point.

probably, it is better to use alert calls here, if the intent is to make it clear to the client that some changes have happened

this one is not used anywhere - should we delete it?

also, it seems that this one is rather pertains to RadioGroup concept, rather than to individual Radio

Every auto-controlled prop must have a default prop associated to it, that is why we have it. I may need to provide example usage of it.

@kuzhelov , I added the usage of the default checked value. This value is intended to be used as a initial check value of the radio button. As the component is auto-controlled, the user should be able to initially set the value of the checked property. Please comment if you have some more doubts on this.

ok - but in that case let me share what my concerns are about. Now we have this defaultChecked to be defined in prop types, but there is no such a property in the component's TS interface - with that it, essentially, means that me as a client is not able to safely specify value for it in the TS code (I mean, this prop won't be advertised as one that is supported by the component, so I could provide some string value, for example).

Sorry, that is my fault, the defaultChecked prop SHOULD be provide in the TS interface. Thanks for the catch!

mnajdova · 2018-09-11T15:25:55Z

The current implementation of the Radio and the example of the group regarding accessibility are behaving the same as the https://www.w3.org/TR/wai-aria-practices/examples/radio/radio-1/radio-1.html The next thing that should be implemented is having the focused border around the buttons. Should we immediately check the button if it is focused, or should be have the same implementation as in the W3 example? What's the proposal for further checks/fixes?

worrying about the fact that this callback method is invoked before state change will be applied to component - in case of potential error in the logic provided by the callback state change won't be applied

Agreed, will move it before invoking the callback.

+    const { checked } = this.state


it would be more robust to obtain this flag directly from e.target.checked - due to async state updates there is a room (although very small one) for the state being out of sync with the component's visual look

Makes sense. Will change it!

couple of comments that we could discuss/address, other than that everything is 👍

-addressed comments in the PR

mnajdova · 2018-09-11T17:09:22Z

As the accessibility aspect of the radio group are pretty complicated, this PR will address ONLY the properties that needs to be implemented in the Radio, and then a dedicated PR will be created for the RadioGroup.

_.invoke() does the check for you

I replaced this with _.invoke, but I prefer much this type of invoking because I know for sure when clicking the property that it is used and invoke somewhere in the code, and with using the invoke, the name of the callback is just a string.

I see you are already discussing this in #207. It would be great if, eventually, we would not need to touch variables in component code.

unfortunately, this makes 'variables defined in theme' story a bit more complicated, as now we might need to get an access to component props there - as it is discussed in #207. This would be quite significant move, and we should consider whether there are any other not-so-radical alternatives. Still, totally agree that we should finally come up with solution that will eliminate this code from component's logic

Exactly, I was not satisfied with having to use the variable in the renderComponent, but as I mention in the other PR we should either be able to define the variables depending on the state and props, or rethink about the API provided so far for the components.
