[fusion-users] Calling ZoomToSelection

[Paul Deschamps]

opps forgot to add this to the list :)

You just need to create a couple of functions and a event register for the
selection:

function onInitialize() {
    var map = Fusion.getMapById('mapwindow');
    map.registerForEvent(Fusion.Event.MAP_SELECTION_ON, selectionOn);


}

// event watcher.
function selectionOn() {
    var mapWidget = Fusion.getMapById('mapwindow');
    var maps = mapWidget.getAllMaps();
    var map = maps[0];

    // get the selection and trigger selectionLoaded with the obj

    map.getSelection(selectionLoaded.bind(null));
}

// selection loaded now zoom to the extents
function selectionLoaded(obj){
    var a = [];

    a[0] = parseFloat(obj.fMinX);
    a[1] = parseFloat(obj.fMinY);

    a[2] = parseFloat(obj.fMaxX);
    a[3] = parseFloat(obj.fMaxY);

    var mapWidget = Fusion.getMapById('mapwindow');
    var maps = mapWidget.getAllMaps();
    var map = maps[0];

    map.mapWidget.setExtents(new OpenLayers.Bounds(a[0], a[1], a[2],  a[3]));

}

You will notice that in the selectionLoaded Func this object will return the
extents of the selection, Now in this function you need to just trigger a
"zoomToExtents" function with the extents


Hope this helps

Cheers
