infoWindow is not shown in the center of the map - google-maps-api-3

Question

Here is the code I'm using to show markers and infoWindows. It's working perfectly.
mapOptions = {
zoom: zoom,
center: getMyCompanyCoordinates,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map($(this)[0], mapOptions)
infowindow = new google.maps.InfoWindow()
createMarker = (company)->
marker = new google.maps.Marker({
position: new google.maps.LatLng(company.latitude, company.longitude),
map: map
})
google.maps.event.addListener(marker, 'click', ()->
infowindow.setContent('content')
infowindow.open(map,this)
)
return marker
firstCompanyMarker = createMarker(companiesData[0])
createMarker(companiesData[i]) for i in [1..companiesData.length-1] by 1
google.maps.event.trigger(firstCompanyMarker, 'click')
However, there is one issue. The infoWindow of the default (firstCompanyMarker) marker is not showing as I need. It's crossing the top edge of the map.
I tried to move the center but there was no result.
lat += 100 #or lat -=100. Anyway it does NOT work
long += 100 # it does work but it's moving the center
#of the map to the left or the right and it's not what I need
mapOptions = {
zoom: zoom,
center: new google.maps.LatLng(lat, long),
mapTypeId: google.maps.MapTypeId.ROADMAP
}
Your ideas? How do I make infoWindow to be shown in the center of the map and to not cross the top edge of it?

Answer 1

Add a the following line after "infowindow.setContent('content')"
map.setCenter(marker.lat-100, marker.lng-100);
However, this is not a real solution. From experience I can tell you that you map is very little for the standard infowindow. You have really 2 options to solve this:
1) Increase the size of the map so the default infowindow will show with the marker in the center of the map or
2) Use a custom infowindow and make it a lot smaller than the default one
Hope that helps!

Answer 2

map.setCenter(marker.lat, marker.lng- (popup.getheight/2));
This should work.

Answer 3

Late answer for the sake of anyone stumbling on this. I had the same problem and noticed that if I closed the infoWindow and clicked the marker, the infoWindow would open and pan to the correct position. Instead of triggering a click, waiting for the tilesloaded event before opening the initial infoWindow was the key.
// Trigger click after tiles are loaded so auto-pan positions infoWindow correctly
google.maps.event.addListenerOnce( map, 'tilesloaded', function () {
infoWindow.open( map, marker );
} );
