Hello,
I'm having problems integrating treepanel (geoext) and wmsgetfeatureinfo
(openlayers). See what I'm trying to do:
1) load dinamically all the layers avaiable in the WMS. That's pretty
easy by means of wmscapabilitiesstore. This example is very clear:
http://api.geoext.org/1.0/examples/wms-tree.html
2) show a popup with info when the user clicks over one of the features
in the map. It's also pretty easy *if* you know previously the layers,
as this example shows:
http://openlayers.org/dev/examples/getfeatureinfo-popup.html
The problem arises when I try to glue this two concepts together.
As I see, wmsgetfeatureinfo needs to be provided with some layers (or
map) to query over. But, I want the popup to show only the info related
to the layers active (the ones with the checkbox on in example 1), so
hardcoding the names of the layers in my javascript file seems not an
option.
So, is there a way to provide the layers to wmsgetfeatureinfo control
later, when an user clicks on the radiobutton on the layer? Or is there
another direction to approach this problem?
best,
amaneiro
PS: sorry about the cross-posting, but I think this question could be
related to both communities: geoext and openlayers. And I can't see to
which fits better.
