|

* Adds support for a "hover" event. The event provides a convenience wrapper
|
||
|
|
* for subscribing separately to mouseenter and mouseleave. The signature for
|
||
|
|
* subscribing to the event is</p>
|
||
|
|
*
|
||
|
|
* <pre><code>node.on("hover", overFn, outFn);
|
||
|
|
* node.delegate("hover", overFn, outFn, ".filterSelector");
|
||
|
|
* Y.on("hover", overFn, outFn, ".targetSelector");
|
||
|
|
* Y.delegate("hover", overFn, outFn, "#container", ".filterSelector");
|
||
|
|
* </code></pre>
|
||
|
|
*
|
||
|
|
* <p>Additionally, for compatibility with a more typical subscription
|
||
|
|
* signature, the following are also supported:</p>
|
||
|
|
*
|
||
|
|
* <pre><code>Y.on("hover", overFn, ".targetSelector", outFn);
|
||
|
