more detailed bounds/hull

[StilgarBF]

A feature in markercluster, that I miss here is the ability to show detailed bounds/hull (area with the inlcuded markers) on mouseover.
cluster.bounds only includes max/min lat and lon which will give me a rectangle.

It would be nice to add a builtin "showBoundsOnMouseover" or at least give access to detailed bounds.

As an alternative: is it possible to get a list of all included Markers from a cluster, to calculate the confex hull?

Hello,

You can find here an example of how to get the markers from a cluster. You also need to enable the feature using PruneCluster.Cluster.ENABLE_MARKERS_LIST = true;. It's not enabled by default because it slows down the application.

I have not implemented a showBoundsOnmouseover feature for different reasons :

• Our application is for mobile touch device first, so no mouseover
• When you have a lot of markers, the hull is more or less a square corresponding to the grid clustering
• You need to update a hull in real-time when displayed

This feature can definitely be added in the library, but I don't plan developing it.

Thanks for the fast response.
got it working now. : http://www.freifunk-karte.de/

I'll close this issue since there are no plans of adding that feature and its no longer an issue for me.

Great work on that Plugin. :-D

Hum, it's pretty nice. Can I keep the showClusterHull on the side? I maybe add it as an option when I will have time.

A small issue : if I zoom using the mousewheel, the old clusterArea stays on the map. I think you can check if the clusterArea is still on the map and use setLatLngs instead of creating a new polygon object.

You can use whatever part you like.
Thanks for the bugnote - will fix that. I think I will remove that poly on zoom.
