<b>ol.interaction.Hover</b> is an interaction to do something when hovering a feature.
|
|
<ul><li>
|
|
The <i>cursor</i> options lets you spécify the cursor when hovering (or use <i>setCursor()</i>)
|
|
</li><li>
|
|
The <i>featureFilter</i> and <i>layerFilter</i> lets you specify which features / layers are concerned.
|
|
</li><li>
|
|
You can use <i>handleEvent</i> options of the <i>ol.interaction.Interaction</i> to extend the interaction.
|
|
</li><li>
|
|
The interaction fires <i>hover</i>, <i>enter</i>, <i>leave</i> events
|
|
you can use to get the feature/layer that is hovering and do some stuff (show a popup, display information, change cursor, ...).
