Polygon infowindows in Gmaps4Rails - ruby-on-rails

Question

I'm using gmap4rails to draw a bunch of fairly complicated polygons that serve as district boundaries. I've got two things i would like help with:
Firstly, I want to associate an info window on click with these polygons. This is an example of my use-case: https://google-developers.appspot.com/maps/documentation/javascript/examples/polygon-arrays
I've tried registering a click event handler in the gmap's callback but it doesn't work and I don't think it's the right approach.
Gmaps.map.callback = function()
{
console.log("'sup");
var infowindow = new google.maps.InfoWindow
({
content: 'you clicked me!',
suppressMapPan:true
});
google.maps.event.addListener(Gmaps.map.polygons[0], 'click', function()
{
console.log("the click event fired");
infowindow.open(map, Gmaps.map.polygons[0]);
});
}
Secondly, I'd like to be able to change the fill-color of these polygons via jquery on some user-events (user clicks a checkbox for example). How would I go about that using the gem?

Answer 1

Replace your method with:
Gmaps.map.callback = function()
{
console.log("'sup");
Gmaps.map.polygons[0].infowindow = new google.maps.InfoWindow
({
content: 'you clicked me!'
});
google.maps.event.addListener(Gmaps.map.polygons[0].serviceObject, 'click', function(event)
{
console.log("the click event fired");
infowindow = Gmaps.map.polygons[0].infowindow;
infowindow.setPosition(event.latLng);
infowindow.open(Gmaps.map.map);
});
}
And change this gem's js line to put true instead of false. I did set to false since I didn't like the cursor change. Anyway it should be in configuration options. Please create an issue on github so that I remember to fix it.
