[Seaside] Google Maps center coordinates

[dtrussardi at tiscali.it]

Thanks James,
i have change the
googleMap GMUsingLatLong>>#'googleMap'


	^GoogleMap new
		setCenter: 45.5267 @ -122.8390 zoom: 11;
		setUIToDefault;
		addScript: self markerScript;
		on: 'zoomEnd' do: [:x :y :z |
			zoomLevelPrc := x.
			zoomLevelAtt := y.
		
		]; 
		on: 'moveend' do: [:x :y :z |
			test:= 'go'.
		];
		yourself.
With this the moveend event is intercept.

Now i d'ont know how i can define the center cordinates.

I think  moveend function  d'ont have parameters.


How i can  run    var center = map.getCenter(); 

Any pointers would be greatly appreciated !
Dario,

|>	See GMUsingLatLong>>#'googleMap' for an example of a callback from the browser to Smalltalk. You could modify the callback so that it persists the arguments instead of simply generating an a|>	lert to display in the browser. Basically, you would send #'on:do:' to the map and use the 'moveend' event.
