/**
|
|
The `Ember.ListItemView` view class renders a
|
|
[div](https://developer.mozilla.org/en/HTML/Element/div) HTML element
|
|
with `ember-list-item-view` class. It allows you to specify a custom item
|
|
handlebars template for `Ember.ListView`.
|
|
|
|
Example:
|
|
|
|
```handlebars
|
|
<script type="text/x-handlebars" data-template-name="row_item">
|
|
{{name}}
|
|
</script>
|
|
```
|
|
|
|
```javascript
|
|
App.ListView = Ember.ListView.extend({
|
|
height: 500,
|
|
rowHeight: 20,
|
|
itemViewClass: Ember.ListItemView.extend({templateName: "row_item"})
|
|
});
|
|
```
|
|
|
|
@extends Ember.View
|
|
@class ListItemView
|
|
@namespace Ember
|
|
*/
