I think its horses for courses really. A lot of people get hung up about<br>
mouseover interactivity and force programmers to do all sorts of gymnastics<br>
to try to make a loosely coupled web app look like as responsive as a<br>
desktop GIS. This is even worse when you are dealing with polygons -<br>
geometry gets filtered and loaded to the client just to give the mouseover<br>
interactivity which looks awful when you zoom in. Also, the area that a user<br>
decides to apply this approach to maynot be controllable by you and could<br>
lead to excessive and unnecessary geometry download times.<br>
<br>
When working with remote data services you may or maynot have access to WFS<br>
in which case you need to use getfeatureinfo requests to get the attributes<br>
on a click. If the data is private to the end user and does not belong to<br>
the WMS data provider at all then uploading geometry into the user's session<br>
from their desktop is the way to go providing the mouseover interactivity.<br>
<br>
Of course if you need the geometry in the client for real spatial analysis<br>
purposes then that is a different issue than doing it just for mouseover<br>
interactivity and is typically done on a more selective object basis.<br>
<br>
Now to answer your question regarding clicking on the vector layer. I found<br>
that you have to make the vector layer the top layer to avoid these<br>
conflicts. So I manipulate the z-index of the vector layer to make sure its<br>
at the top.<br>
<br>

Subject: [OpenLayers-Users] Vector layer with
map.events.register("click")<br>
<br>
<br>
Dear all<br>
<br>
I retrieve a set of points from GeoServer as a WMS tile. Using<br>
map.events.register('click',...) I attempt to retrieve information about a<br>
specific point when the map is clicked, using a bespoke WFS call.<br>
<br>
I am now required to provide some data about each point on mouseover so have<br>
been investigating OpenLayers.Layer.Vector and<br>
OpenLayers.Control.SelectFeature. My initial idea is to keep my original WMS<br>
layer and supplement it with a WFS-driven Vector layer. See this mock-up:<br>
<br>
<a href="http://v5dev.elgin.gov.uk/sw.html" target="_blank">http://v5dev.elgin.gov.uk/sw.html</a><br>
<br>
The idea is to set the opacity of the style of the vector objects to 0.01 to<br>
take advantage of the "selected" behaviour while seemingly not
affecting the<br>
map appearance. But using this two-layer method, the map clicks are not<br>
triggering over the vector objects.<br>
<br>
So... two questions:<br>
<br>
1. Is there a way to make map.events.register('click',...) work when a<br>
vector object is selected?<br>
2. Should I abandon this and simply use the vector layer exclusively<br>
(plotting the relevant images at the appropriate points)?<br>
<br>
Would appreciate your advice.<br>
<br>
Thanks<br>
Stuart<br>
