Slider: option to highlight current data marker

[bill]

Option to highlight the current data marker (data markers == the numbers for the slider ex: 50%). So for example, if carrot is positioned at 50%, then 50% will be red, but 25% and 75% will be black.

If not positioned exactly at a data marker then nothing would be highlighted.

Taken from ​IBM Design Leadership recommendations.

Does marking something with a different color violate a11y rules? I think this ticket should be used to add event processing to the slider rules/labels widgets so the user can customize what happens easily.

Since you are only using color to enhance the information, it is probably acceptable but it would be better if, in addition to color, you could also add a means to distinguish the current data marker. This could be done by adding some type of border using dijit_a11y styles or even better, also make it bold or underline the markder so that it works for color blind folks in normal (not high contrast mode) as well.

From Julie Santilli (IBM Visual Design): showing a value-tooltip pointing to the slider bar value whenever the slider is focused and also whenever the slider handle is being hovered over is preferrable to static data highlighting.

show tooltip with value as slider handle is moved or hovered

Hmm, the tooltip in the patch doesn't seem very useful since the tooltip disappears as soon as the user starts to move the mouse. (Keyboard has a similar problem: the tooltip keeps popping in and out.)

I'm not sure what the goal is... a tooltip is useful because it can show an exact value, like "34.5678" where there are only tick marks for "30" and "40". OTOH the tooltip disappears as soon as focus/mouse is moved away from the slider, so it's doesn't seem to solve the original request of this ticket.

Jjust talked to Julie. Her group rescinded the original request to highlight the current data marker as it was thought to be too noisy (changing as the user moves the mouse), and requested this instead, to highlight the exact value.

Can you create a new ticket about the tooltip, as it's really a different feature?
