CircularProgress_Stylesheet.yaml

A circular progress indicator: determinate with a value, indeterminate without.

The look of CircularProgress (in Progress indicators). How component stylesheets work.

The stylesheet

# CircularProgress: the look of each part of the component, by the part's id.
# A value in {{ }} is one of the component's parameters.
styles:
  - id: root
    style:
      width: "{{ size }}"
      height: "{{ size }}"

How it is tied to the component

CircularProgress_Component.yaml holds the structure: the parts, each with an id. This file holds the look: each rule's id names a part, and its style is what that part looks like. When a view uses component: CircularProgress, Tesserae fills in the parameters (a value like "{{ width }}" becomes the width the view passed), picks a branch of any if:, and puts each rule under the style the part already has, so a part's own style: always wins.

The parts

root (CircularProgress)

Field	Value	What it does
width	the size parameter	Pixels, auto (its content's size, or stretched), or a percentage of the parent such as 50%.
height	the size parameter	Pixels, auto (its content's size, or stretched), or a percentage of the parent such as 50%.

What it makes

With size: 40, value: 0.5, each part's style is:

root: {width: 40, height: 40}

Changing it

Put a CircularProgress_Stylesheet.yaml next to your views. Its rules go over this file's, field by field:

styles:
  - id: root
    style: {width: tertiary}
