how to show/open InfoWindow on mouseover?

Hello everybody,

I am looking for a solution to open/show the InfoWindow when hovering the mouse over the corresponding address in a views list. I made a page-view of locations (locations module) and added a gmap showing the corresponding locations as attachment. That works perfect so far. Also the InfoWindows are popping up when clicking one of the markers.

What I am trying to achieve now is that the Infowindow corresponding to the item in the locations list pops up when hovering over the list item. To give you a better idea what I mean take a look at that site:
http://yellow.local.ch/en/q/basel/Hotel.html
It has quite the same concept of what I wanna do. If you move the mouse over an item on the address list, you get a kind of InfoWindow on the map.

As I understood it so far, it's merely a matter of JavaScript (what probably could get included in the theming of the page-view?) but is there maybe a module or an option in one of the used modules which I didn't find yet?

Any sugestions are welcome!!

Thanks!
