How do I get Google Maps to show a whole polygon?
google-maps, gpolygon
Solution
You can get the centre point of a polygon by using `aPolygon.getBounds().getCenter();` and then using the `GLatLng` returned with the `myMap.setCenter()` method.
To get the zoom level, you can use `myMap.getBoundsZoomLevel(aPolygon.getBounds());` then use this with `myMap.setZoom()` method.
Problem
I have a set of GPolygon objects which are attached to objects in my domain model and are added to a map on my page. The domain objects are being shown in a list on the same page and when the user clicks on one of them I want to show the associated polygon. I want the whole polygon to be showing and ideally I want the map to be centred on the polygon centre. I was hoping that there would be a maps API call along the lines of... ``` myMap.makeSureYouCanSeeAllThisPolygon(aPolygon); ``` but I haven't been able to find one. If I have to do this manually, then I can obviously figure out the centering easily, but how do I figure out the zoom?
