Set up the center of a map with Google Layer as basemap in OpenLayers and GeoExt?

Question

I looked on similar questions but in vain. The map is working fine but has a center of (0,0) as returned in the Firebug console not (-8, 32) that I want. I did the projection transformation.. Here is my code :

zoom    )
Set the mapObject to the specified center and zoom

Parameters

zoom    {int} MapObject zoom format

Answer 2

Actually, I had to give a look on GeoExt Documentation as well especially the class GeoExt.mapPanel link here. The center of the map and the initial zoom must be specified in there and it worked finally:

    (...)map.addLayers([Gmap, institutions, pays]); 
    var point = new OpenLayers.LonLat(-6, 33); 
    point.transform(new OpenLayers.Projection("EPSG:4326"), map.getProjectionObject());
    var mapPanel = new GeoExt.MapPanel({
        region: 'center',
        height: 550,
        width: 1000,
        map: map,
        zoom: 4,
        center: point,
        title: 'Carte'
    });
