How to add listener for overlays

[tomar]

Hi,

I am facing a small issue.
When I am trying to open a info window on click of a custom overlay,
but Its not working. However same is working with marker. As far as I
know both extends MVC object but I am not able to find the cause of
problem.

....
...
....
var marker = new google.maps.Marker({
position: myLatLng,
map: map,
title: 'HELLO'
});
var infowindow = new google.maps.InfoWindow({
'content': 'Hello Tomar'
});

Working code for marker->
google.maps.event.addListener(marker, 'click', function() {
infowindow.open(map,marker);
});

Not Wroking for overlay ->
// USGSOverlay is custom overlay so overlay is coming on map -
copied sample code
var overlay = new USGSOverlay(bounds, srcImage, map);

// not able to add the listener for click event on overlay :(
google.maps.event.addListener(overlay, 'click', function() {
infowindow.open(map,overlay);
});

Would someone please suggest me to make this working?

I haven't tried doing this with an overlay but if you can afford to use a polygon instead, I can confirm that will work.  As a fallback I believe you could surround the overlay with a transparent polygon.

Is your custom overlay triggering a 'click' event? Remember that a
mouse event is a DOM event and "addListener" only listens for custom
events. Basically you have to make sure your custom overlay listens
for the DOM mouse event for whatever element your overlay uses and
then call google.maps.trigger(this, "click") whenever the user clicks
the overlay

Sorry, using this wouldn't work. Doing this in a custom overlay would
work:

var me = this;
google.maps.event.addDomListener([whatever element is used], "click",
function(ev) {
var e = ev||window.event;
google.maps.trigger(me, "click", e);
});

Sorry for seeing these replies lately,

Actually I got the solution so for now I am marking this thread
closed.

Only silly mistake was there. Now its working fine.

Anyways Thanks for your help.

Tomar,

Did you get this working?

I am facing the same problem... but ONLY on iPhone.

The same code is working fine on Android phones and Chrome Windows.

How did you fixed this?

I managed to make it work with:

USGSOverlay.prototype.addClickEvent = function() {
google.maps.event.addDomListener(myCustomOverlay.div_, 'click',
function() {
alert("you clicked!");
});
}

but on the iPhone is weird, if I tap on my overlay when the map is
rendered it works, and then it's not working anymore while on Chrome
it keeps working whenever I click on it. Did someone experience the
same problem?
