Interaction with Map and Map Features form outside of the Leaflet Markerclustered map

Taking advantage of the recently added functions to trigger events on features and maps from outside of the Leaflet Markeclusterer context (http://drupal.org/commitlog/commit/42060/6e211c3f4271ed822d3ade2db18048b...)

I implemented this very successfully on this page (work in progress …):

http://www.italomairo.com/geoblogcms/en/ip-locations-leaflet

Just try to mouseover and mouseout the "zoom in map" highlighted in the left list … to see how this (successfully) works.

In this case the map view is generated by the ip_geoloc module (http://drupal.org/project/ip_geoloc), that made me able to change the icons on dynamic values of the features themselves … but the logic is the same with the Leaflet (& Markercluster) Module itself for interaction.

It is awesome and now works great! …
but it took "not just a while" to figure out how to do that. More details on this solution is explained here: http://drupal.org/node/1998596

For me this now both works with the Leaflet Module and the Leaflet Markercluster one , but to make it working I needed to alter the js files of both the modules, as I needed to access also to the initial map.center and the map.zoom of the created Leaflet Map … and on the Markercluster one to the map itself (not yet implemented seems ..:)

In the Leaflet Markerclusterer Module, I had to make some fine integration to the "leaflet_markercluster.drupal.js", just with the following few lines of code … (diff file attached)

Available for more clarifications, I am looking forward to seeing this integrated/committed soon in the last dev of the Leaflet Markeclusterer module …

PS : parallel and very similar issue has been posted right now in the Leaflet Module (http://drupal.org/node/2005328/edit)
