GMaps V3 InfoWindow - disable the close “x” button

Question

From what I see, in v2 of GMaps API there was a property \"buttons\" of the InfoWindow object that one could define in a way that given InfoWindow has no close button:

Answer 1

I couldn't get any of the $(".gm-style-iw").next("div").hide(); answers to work even when calling the code after the DOM was loaded, since there was a delay between the code being called and the info window being created. What I did was create an interval that runs until it finds the info window and removes the "X" element. If there's a better way please tell me.

var removeCloseButton = setInterval(
    function()
    {
        if ($(".gm-style-iw").length)
        {
            $(".gm-style-iw").next("div").remove();
            clearInterval(removeCloseButton);
        }
    },
    10
);
