polygon mouseover

[Jason Sanford]

I know there is no 'mouseover' event for a Polygon but has anyone successfully implemented their own solution? I want to highlight a polygon (change fillColor property) when I mouseover a polygon and open an infoWindow when I click a polygon (I've already got this).

Thanks

It is difficult to do with tiled polys. Each tile may contain
multiple polys. Each poly may be partially resident in multiple
tiles. For CANVAS, it means completely rebuilding every tile
containing a piece of the poly. For SVG & VML, individual polys can
have color changes applied but it still involves multiple tiles.

It can be done by inserting / removing extra shapes for the "rollover"
element in the existing tile structure. Unfortunately, CANVAS uses a
different coloring algorithm than SVG & VML.

See my solution on this thread:

After a quick look at your code. It looks like you essentially wrapped a polygon with a bigger transparent polygon and you hide the tooltip when the 'mousemove' event fires on the big transparent polygon.  Unfortunately, I don't think this will help with my application as I have multiple polygons that most likely share a boundary edge, so it would be hard to wrap each one with a larger polygon.

It is, however, a very creative solution that I can probably use on a few other projects.  Thanks for the tip.

Any updates on this?
I'm looking for something similar myself with the fillcolor.

This shouldn't be a big problem? As the bigger polygon lies behind the
others. You could add several listeners for all your polygons? Or
would this result in multiple tooltips (in the example)? I assume the
tooltip text would just change..

Hi Richard,

Polygon's now support mouse events, please read the reference (http://code.google.com/apis/maps/documentation/v3/reference.html#Polygon) for more information.

It's about time they realize that its an essential feature to have.
Thanks for the info Luke.
