[Slider] Port component #11040

epodivilov · 2018-04-16T20:15:35Z

Added implementation of the Slider component according to the Google guidelines

PS: Something happened to my previous PR so I created a new one.

Closes #4793

Thank @mbrookes for this, when can we expect this merge?

epodivilov · 2018-04-27T16:21:16Z

@mbrookes what about this pull request?

mbrookes · 2018-04-27T17:30:46Z

@epodivilov My task for this weekend.

mbrookes · 2018-04-28T16:31:50Z

Okay, this is starting to take shape!

Keyboard input in the basic slider is 💯👌 , however mouse / touch input has the same granularity (1% step) as keyboard input, rather than being continuous, which gives a course feel to the movement. v0 had the same issue, so it would be good to address that here. It isn't a show-stopper, but I fear if we don't fix it now, it might get left like this.

Since you're using ButtonBase for the thumb, it would be preferable to use the focus ripple when keyboard focussed rather than a custom style.

The vertical slider seems backwards - I think the default should be from bottom-to-top, with reverse being top-to-bottom.

@Pajn pointed out that the use of top, left etc. for positioning is causing a performance hit. Did you have an opportunity to look at using transform: translate() and transform: scale()?

The testsh ave been renamed from .spec.js to .test.js

Once we get these last bits sorted, we can dig into code review (I have been focussing mostly on functionality).

Thanks for all your hard work! 👏

epodivilov · 2018-04-29T16:07:30Z

@mbrookes Thanks for review.
First of all I would like to note that the ripple effect is not according to the google guidelines.
About performance issue I will try to check.

About mouse / touch behavior I have a question. Right now I round value to step. if you do not do this, then which sign is worth rounding? For example: I clicked roughly in the middle of the slider and got value 0.5987654321. Now I will return the value 0.59. But it same value, which you can get by keyboard.

mbrookes · 2018-04-29T22:05:54Z

@epodivilov You're right, no ripple in the spec, or the MCW (or other) implementations. I'm a little surprised at that, as the ripple is designed as a visual affordance to make the focused component more obvious.

Regarding rounding the value - MCW don't round the value returned, so the developer can decide what precision to apply: https://material-components-web.appspot.com/slider.html

However unlike MCW, I believe we should round aria-valuenow to a sensible level of precision (3 digits?), so that a screen-reader user isn't potentially faced with an unending list of spoken digits if the screen-reader doesn't truncate it.

mbrookes · 2018-04-29T22:11:24Z

One other thing you can do as part of this PR is to update the Supported Components page. You can follow the SpeedDial example, but I think it would be a good idea to add the checkmark to both Slider and SpeedDial.

mbrookes · 2018-05-09T11:51:17Z

@epodivilov are you still working on this? It feels like we're very close to final review.

epodivilov · 2018-05-11T09:05:11Z

@mbrookes Yes, I still working on this PR. I had a small vacation. I'll try to fix it this weekend.

mbrookes · 2018-05-11T14:13:32Z

Thanks @epodivilov Hope you had a nice break! ☺️

epodivilov · 2018-05-11T20:57:26Z

@mbrookes I fixed rounding of values and updated the Supported Components page. Please, review last updates

mbrookes · 2018-05-11T21:32:01Z

@epodivilov Looks like something's gone wrong with the branch. You don't need to create a new PR, just clean up the brach and force push.

This is looking great! Thanks for working on it.

I meant for this to be in the core material-ui so we can reuse it there, but I can fix it up later.

epodivilov · 2018-05-12T13:28:20Z

@mbrookes What does you mean "clean up the branch"? Like this https://stackoverflow.com/a/25357146 ?

Pajn · 2018-05-12T13:39:34Z

I would personally rebase and squash but that is of coursee up to you what you are most comfortable with. The end result is a nice simple commit on top of the current v1-beta in both cases :)

mbrookes · 2018-05-12T14:20:05Z

@epodivilov it wasn't about squashing (we can do that at merge), but there were somehow a bunch of unrelated commits in the PR. I wasn't sure if a rebase would be sufficient, or whether you'd have to cherry-pick your commits back onto a clean branch so "clean up" meaning whatever it needed to get it back into a reviewable, mergeable state.

@goto-bus-stop Great news. Should I fix something in my code, or do you fix it yourself? And when you plan to merge the PR?

Oh I don't know, I'm not a maintainer, just a user excited for this PR 😛

@epodivilov Yes please, if you could rename that prop as @goto-bus-stop pointed out, that would be great! Sorry I missed it.

Can potentially be shared at some point with colorManipulator.

That was the original intention - we have a clamp function in a couple of places. I plan to consolidate them once this is merged.

Why do we need to trigger the event during the capture phase? It's the first time we do such.

I need to prevent page scrolling when moving the slider (function preventPageScrolling).I should catch event before preventing, so I use capture phase.

The default component is a div. I don't think that you need to call findDOMNode.

To prevent page scrolling, I need to catch touch events and prevent them from entering outside of the container. So I need get a link to container component.

This is already packages into the keycode dependency. No need for duplicating it.

the capture argument is never used.

By the way. I'm not sure you need this helper function.

This function is used to detect movement of the mouse outside the component, as well as to detect the termination of interaction with the component. So I can remove unused argument, but I think is not a problem. If this function move to all helpers function somebody might need this parameter.

You are using a function with the other helpers, not an arrow, maybe we should be consistent.
