Progressbar: Support value: false for indeterminate progressbar

[Scott González]

We had previously said that indeterminate progress bars should be a separate widget. However, there is a common enough use case where you may want to start providing feedback about that a task has started before you know the actual progress. In this case you may want to start with an indeterminate progress bar and switch to a determinate progress bar as soon as you have enough information to provide details. In order to support this, we will allow the value option to be set to false to indicate that the progress bar should be indeterminate.

Looking at picking this up. Is there any spec as to what an "indeterminate" toolbar should do or look like? Some simply move from 0-100% continuously.

In fact, no, indeterminate progress bars should not move from 0-100%, only determinate progress bars should do that. See ​http://wiki.jqueryui.com/ProgressIndicator Section 1 for more info.

Got it. Thanks for the links.

Replying to scott.gonzalez:

A bit of clarification:

• Can you switch between false and a numeric value and back again?
• How do you see the graphic being specified for the indeterminate state? (Would this be passed in as an option? Would we simply apply a user defined class name maybe specified in the options. Or apply a predetermined class name or style?)

Replying to richwag:

Yes, all widgets allow changing any option at any time.

• How do you see the graphic being specified for the indeterminate state? (Would this be passed in as an option? Would we simply apply a user defined class name maybe specified in the options. Or apply a predetermined class name or style?)

Unknown. Perhaps just adding a class that defaults to a slanted stripe background. We need to discuss this with the design team.
