Hi,
I've been slogging through getting this to work (my map renders on the page
now) and I'm having trouble getting my head around how layers and the
click/hover callbacks work. The goal is to get a popup working on arbitrary
points added to the map.
I have a map with an Image baselayer and a Vector layer where the features have
been added, like so
var newPoint = new OpenLayers.Feature.Vector(new OpenLayers.Geometry.Point());
var lonlat = map.getLonLatFromPixel(new OpenLayers.Pixel(x,y));
newPoint.geometry.x = lonlat.lon;
newPoint.geometry.y = lonlat.lat;
targetLayer.drawFeature(newPoint,
OpenLayers.Util.extend(OpenLayers.Feature.Vector.style['default'], {}));
So far so good! The points appear in the targetLayer as expected. (But, when
I use the zoom control, they don't zoom with the map, but that's another day's
problem...)
I added a OpenLayers.Control.SelectFeature
selectControl = new OpenLayers.Control.SelectFeature(
targetLayer,
{onSelect: onTargetSelect, onUnselect: onTargetUnselect});
selectControl.activate();
map.addControl(selectControl);
When click on a newPoint on the map, the reaction is like I'm selecting the
baselayer. What I can't figure out is how to make the targetLayer the active
layer, as from reading the mail logs, it appears like the SelectFeature works
for the active layer. I've read/reread the sundials.html code (as that's close
to the affect I want) and can't figure out what I'm doing wrong.
With Regards,
gene
