Re: [Gwt-openlayers-users] Dynamic sizing of map
|

I've tried implementing the Map.updateSize() method in GWT-OL, and it works.
However, I had to call this method in my client code.
For more transparency, we could call updateSize() in the MapWidget.getMap()
method, which is responsible of the instanciation of Map :
*
public Map getMap()
{
//The preference here is lazy initalization
if (map == null)
{
if (options == null)
map = new Map(getElement());
else
map = new Map(getElement(), options);
map.updateSize();
}
return map;
}*
What do you think ?
