```js script

import { html } from '@mdjs/mdjs-preview';
|
|
import './assets/custom-progress-indicator.js';
|
|
```
|

|
## Extended indicator with a custom visual
|
|
|
|
`LionProgressIndicator` is designed to be extended to add visuals. Implement the `_graphicTemplate()` method to set the rendered content and apply styles normally.
|
|
|
|
### Example extension
|
|
|
|
```js
|
|
class CustomProgressIndicator extends LionProgressIndicator {
|
|
static get styles() {
|
|
return [
|
|
css`
|
|
:host {
|
|
display: block;
|
|
}
|
|
|
|
.progress--icon {
|
|
display: inline-block;
|
|
width: 48px;
|
|
height: 48px;
|
|
animation: spinner-rotate 2s linear infinite;
|
|
}
|
|
|
|
.progress--icon--circle {
|
|
animation: spinner-dash 1.35s ease-in-out infinite;
|
|
fill: none;
|
|
stroke-width: 6px;
|
|
stroke: var(--primary-color);
|
|
stroke-dasharray: 100, 28; /* This is a fallback for IE11 */
|
|
}
|
|
|
|
@keyframes spinner-rotate {
|
|
to {
|
|
transform: rotate(360deg);
|
|
}
|
|
}
|
|
|
|
@keyframes spinner-dash {
|
|
0% {
|
|
stroke-dasharray: 6, 122;
|
|
stroke-dashoffset: 0;
|
|
}
|
|
50% {
|
|
stroke-dasharray: 100, 28;
|
|
stroke-dashoffset: -16;
|
|
}
|
|
100% {
|
|
stroke-dasharray: 6, 122;
|
|
stroke-dashoffset: -127;
|
|
}
|
|
}
|
|
`,
|
|
];
|
|
}
|
|
|
|
_graphicTemplate() {
|
|
return html`
|
|
<svg class="progress--icon" viewBox="20 20 47 47">
|
|
<circle class="progress--icon--circle" cx="44" cy="44" r="20.2" />
|
|
</svg>
|
|
`;
|
|
}
|
|
}
|
|
```
|
|
|
|
### Result
|
|
|
|
```js preview-story
|
|
export const main = () => html` <custom-progress-indicator></custom-progress-indicator> `;
|
|
```
